Dali iO-12: 3-minute review

The delightfully delicious Dali iO-12 are easily in my top three headphone designs of all time, aesthetically speaking, and I've seen some gorgeous headphones in my time. I almost want to take a bite out of them, or at least dunk them in something creamy and highly calorific. And it's not just looks and luxe either – aptX Adaptive is here, as is 24-bit/96kHz resolution if you're going USB-C wired (both 3.5mm and USB-A to USB-C cables are provided) so you're getting the trousers and well as the talk, so to speak. 

While the Dali iO-12's bid for entry to our best wireless headphones guide surely includes that USB-C port for hi-res audio passthrough (take note, iPhone 15 and Apple Music users) the sense of pride in ownership one feels wearing these striking yet understated headphones is a massive part of their appeal. They look expensive (because they are) but more than that, they sound expensive. 

Forget special spatial audio side-sauce, forget customising what the on-ear controls do, forget EQ tweaks (other than the solo bass boost button) forget sound zones, forget speak-to-chat features and forget tweakable ANC. There's none of that here. In fact, there's no app here at all, so forget any visual representation of what's going on inside your headphones. 

That said, they're some of the best noise-cancelling headphones around even without the scope to tweak modes, levels or adaptiveness. And this is because what you chiefly want when you stick on a pair of noise-cancelling headphones is for them to be worthy of their name claim and cancel some noise. What you need to know is that Dali's iO-12 reduce noise very well, thus setting the stage to deliver excellent audio to your ears.

I'm not at all surprised. Although TechRadar's reviews of Dali gear to date hone in the brand's speaker output (including the new Epikore 11, if you skip to point three here) my tenure at our sister publication, What Hi-Fi?, saw me help review the 2019-issue Dali iO-6 and Dali iO-4, the Danish audio specialist's first ever foray into the world of wireless over-ear headphones and one it approached as very much a 'personal speakers for your ears' endeavour. However that sounds, those inaugural cans were nothing short of excellent for detail, finesse and form, marred only by a fractionally over-cautious delivery that lacked an extra ounce of punch for the price. 

To atone for this (a mere four years later), Dali has added a button to boost bass. I don't particularly like it, but it's there – and the hi-fi sound profile is so enjoyable I don't care. There's also a new patented Soft Magnetic Compound (SMC) magnet system, which I'll discuss later because that is inspired.

The ear pads here in the newest model are bigger than previous models, and while they're very well padded, make no mistake: this is a big set of over-ears and could swamp a smaller wearer – or overheat the user who tends to suffer from overly warm ears. If ever there was a set of over-ears for the fall temperature drop, it's the Dali iO-12. I love the coziness of them, even if the headband fell back on my crown a little more often than I'm used to – a 370g, they're certainly not the lightest on the market.

In summary, if you like to keep things simple and you want a quality, mature, hi-fi grade listen plus an aesthetic that purrs "I'm very important; do leave me alone", you've met your match in the Dali iO-12. However, if you prefer all the whistles and bells of an app-enhanced experience, you'll find a more suitable proposition for less money in the likes of the Sony WH-1000XM5, Bose QuietComfort Ultra Headphones, or even the mighty Bowers & Wilkins Px8. 

I did warn you they're expensive…

Dali iO-12 review: Price & release date

  • Released May 18, 2023
  • Priced $1,499 / £999, which is around AU$1,870

The Dali iO-12 were unveiled at the prestigious annual hi-fi trade show, High End Munich, in May 2023.

And high end is certainly what they are. If you want them, you'll need deep pockets; they're more expensive than premium options such as the Focal Bathys ($799 / £699 / €799, around AU$1,210) or the Bowers & Wilkins PX8 ($699 / £599 / AU$1150). 

OK, they're not quite as dear as the wired Meze Audio Liric ($1,999 / £1,799 / AU$3,399) but still, they're easily four or five times the price of many quality, aggressively priced options out there. 

Consider for example the Shure Aonic 50 Gen 2, ($349 / £349 / approx. AU$540), the Sony WH-1000XM5 ($399 / £380 / AU$649), the Bowers & Wilkins PX7 S2 ($399 / £379 / approx. AU$575), the Edifier Stax Spirit S3 ($399 / £330 / approx. AU$640) or the Sennheiser Momentum 4 Wireless ($349.95 / £300 / AU$549.95) for starters. 

Now, consider that every single one of the options above except the Dali iO-12 has a companion app. That performance had better be good, no?

Dali iO-12 review: Features

  • New Bass/Hi-Fi button
  • USB Aaudio supports up to 24-bit/96kHz resolution
  • Excellent ANC – but not as fully featured as the competition

Let's talk stamina first: 35 hours is very good. It's better than the 30-hour claim of the TechRadar 2023 Award-winning Bowers & Wilkins PX8, although not as good as the 45 hours you'll get from the Shure Aonic 50 Gen 2 or the 80-hour staying power of the Edifier Stax Spirit S3, but the latter is a somewhat skewed contest since the Edifier headphones are devoid of ANC. Also, I can confirm that Dali's battery life claim holds true.

Multipoint? Yes, it's here – and once you get used to that fact that the physical buttons are all on the right earcup, altering volume (by pushing the outer lip of the circular right earpiece either up at the top or down at the bottom), handling playback and scrolling ANC profiles works a charm. I did find myself turning them off occasionally in error, forgetting that the ANC button (which scrolls between "Transparency", "ANC off" and "ANC on")  is actually further forward on the earcup and a little trickier to locate, but these controls are certainly dependable.

What these physical buttons are not is customizable in any way. What am I talking about? Well, other headphones give us options to change what a single or double press might do. The competition might also let you deploy sidetone to amplify your voice during calls, set a few EQ profiles for different music genres, switch auto-pause on or off, offer sound zones, give you the chance to prioritize audio quality or a stable connection, or even switch up the vocal notifications to a female voice. None of that here. 

Usually in this section I'd provide three screenshots of Dali's companion app and a bit on its merits or shortcomings. Only, I cannot do that because there isn't one. One could argue you don't need an app if the sound from the box is good enough – and to a degree I'm inclined to agree. But anyone who's used Sennheiser's sound zones, deployed Bose's new Immersive Audio or created their own EQ profile for maximum hip-hop track enjoyment may beg to differ. In the end, it's up to you. 

One new button on the iO-12's right earcup, nearest your crown, is denoted by an EQ symbol. Press it and a male voice utters "bass" or "hi-fi" depending on how many times you've pushed it. It's something extra and it adds value, although I prefer Dali's integrated, refined hi-fi listen. Rather than unearthing that extra ounce of clout, snap and energy you might be hoping for, the bass booster amplifies the low end but draws a veil over the other frequencies somewhat.

The good news? The noise cancellation here is very good. The levels are not selectable on a slider (look to the Bose Noise Cancelling Headphones 700 for this) but still, when it's on, it does create a lovely bubble of silence. 

  • Features score: 3.5/5

Dali iO-12 review: Sound quality

  • Neutral, revealing separation with oodles of clarity 
  • Treble frequencies are particularly insightful and agile
  • Can still be beaten (just) for fun and zeal

What I love about larger over-ears is the circumaural sound dispersion and the Dali iO-12 serve up the goods here – in a big way. Kicking off with Far Beyond the Sun by Yngwie Malmsteen on Tidal (a FLAC file), cymbal crashes and keys approached my left ear with newfound direction and clarity as the guitar came in centrally.

My Chemical Romance's To the End reveals whispered backing vocals darting underneath each ear as axe crashes stay over on the left and the melody comes through the right. Gerard Way's vocal is as overly close to the mic as it should be in a cohesive and musically pleasing mix across the frequencies. 

Switching to an Apple Music file on my iPhone, the key progressions in Joni Mitchell's Blue are three-dimensional and moving. My playlist continues to All I Want, where each musical passage is given due diligence in a layered performance – strummed guitar chords in my right ear, the rhythm in my left, Mitchell's ponderous artistic vocal stylings and trills upfront and center. Honestly, it's emotional – particularly through the sparkling treble. Dali's iO-12 offer immersive listening without the extra parlor tricks; it's dynamically agile listening inside your head. I applaud it. I can (and have) listened to it for hours. If you're a singer, you'll want people to listen to your voice on these cans. 

Some listeners may want an extra iota of what I can only call fun; a cheekier rise and fall, a bit of added oomph, a punchier bass injection. You can look to Bose or JBL for these marginal sonic additives to the audio curve, I'll take the insight, detail, neutrality and precision of the Dali iO-12's hi-fi profile, thank you.

  • Sound quality score: 5/5

Dali iO-12 review: Design

  • USB port on the right earcup, 3.5mm jack on the left
  • Classy design which lies flat but doesn't fold
  • Very large earcups and pads

The iO-12 are the world's first headphones to feature Dali's patented Soft Magnetic Compound (SMC) magnet system. This is an important build feature since it uses the same material found in Dali's high-end speakers, but to understand it fully you need to know about 'hysteresis'. Conventional magnets in a speaker design can introduce an unintended resistance to the voice-coil, which can lead to unwanted distortion in the audio signal, aka hysteresis. Dali's SMC technology, combined with the company's signature paper fibre cones, promises to significantly reduce hysteresis and lower uneven harmonic distortion drastically. And I think it's a huge success.

Looking for a set of foldable headphones – the kind that concertina up for easier portability? No dice here sadly. In the same way that the Sennheiser Momentum 4 Wireless, Focal Bathys or newer Fairphone FairBuds XL do, these cans have cups that can rotate to lie completely flat (and they do so silently, with no clicking whatsoever during adjustment), but the square hard-shell case is really quite big and not one that can easily slip into a bag unnoticed. 

The build here is really quite beautiful though (it does include real leather, vegans take note) and there is ample padding wherever you need it, particularly from the rectangular pads attached to the circular earcups. That said, they're big. You may love this; I certainly do – it helps to deliver a wide soundfield and there's nothing quite like a huge set of over-ears wrapped around your head to signal "No words, please" to the public. However, once or twice during testing and despite the about-perfect clamping force, I did find the iO-12's headband slipped back on my crown as I walked. I think it's their sheer size. 

Ultimately, these are cans that aren't backwards about coming forwards. Photos don't do it justice but the metallic circular accent on each earcup catches the sun beautifully – I did get regular compliments while wearing them. 

I like that the physical buttons are all one earcup since I'm right-handed, although those with larger fingers (or lefties) may find this a little fiddly – only the ANC button takes a bit of practise to locate quickly. 

What is a tad strange is the location of the wired input options, with one on each earpiece (USB-C on the right, 3.5mm jack on the left) – but this is relatively small fry and something you'll also find on the Shure Aonic 50 Gen 2. The supplied fabric-covered cables feel premium, robust and impossible to tangle. 

There's very little sound bleed here, but there's also no IP rating for water resistance, so you should be careful in very heavy storms – particularly at this price. 

At 370g, they're equivalent to something like Apple's AirPods Max (384g), and like the AirPods, they use clamping to distribute that weight comfortably. Considering Sony's WH-1000XM5 are quite a bit lighter at 249g, the Dali definitely feel a tad more substantial in the scheme of headphones.

  • Design score: 4.5/5

Dali iO-12 review: Value

  • Premium looks, premium sound, premium price
  • USB-C audio connection adds flexibility and hi-res audio
  • There's no app – and cheaper options have one

There's no getting away from it: these headphones are expensive. But what they do, they do extremely well – and by that I mean you're getting excellent sound quality and very decent ANC.

That said, if you want the best (and by that I mean tweakable) transparency profiles, EQ presets, button tweaks, spatial audio, or perks money can buy, spend it elsewhere, on the Sennheiser Momentum 4 Wireless, Bose QuietComfort Ultra Headphones, or the Sony WH-1000XM5. 

Buying headphones usually involves a compromise (omission of a particular hi-res codec, poor call quality but great sound, lack of water resistance), and here, the glaring omission is app support and smart features. There just aren't any. Dali actually lists "No app required" as a feature in the iO-12, but we're not so sure. 

The battery level is more than sufficient at 35 hours, the build is incredibly beautiful and the sound is supremely detailed and integrated. If you want an extra ounce of oomph though, you'd be better off looking to Bose. 

  • Value score: 4/5

Should I buy the Dali iO-12?

Dali iO-12: Also consider

How I tested the Dali iO-12

Unmistakably fall weather calls for warm, chocolate brown Dali over-ears. (Image credit: Future)
  • Tested over two weeks, listened against the Edifier Stax Spirit S3, Sennheiser Momentum 4 Wireless, Bowers & Wilkins PX8 and Focal Bathys
  • Used on long walks on public streets, at work in a busy office, on a train, and at home
  • Listened to Tidal Masters, Apple Music, Qobuz and Spotify on an iPhone 12, a Sony Xperia 1 V, and from MacBook Pro

To test headphones is to invite them into your life – how the case fits in your bag is just as important as how they slip onto your head. The Dali iO-12 became my daily musical companion – after a thorough run-in period. And just as Dali is a trusted name in speakers, I now trust what the firm can do with personal speakers that wrap around your head. 

These headphones accompanied me to work on busy weekdays (walking brusquely to the station; boarding a train and taking the London Underground; at the office) and walking along the blustery seafront – a great way to test any wind-interference from mics during calls.

To check the audio quality across the frequencies, I listened to various playlists across various music genres (spanning everything from grime to classical) on Apple Music and Tidal, but also to podcasts and albums on Spotify – plus of course YouTube tutorials (on how to change a light in my refrigerator, most recently) from my MacBook Pro. 

I’ve been testing audio products for over five years now. As a dancer, aerialist and musical theater performer in another life, sound quality and the user experience have always taken priority for me personally – but portability, security and comfort come a close second. 

Shure Aonic 50 Gen 2 review: glorious wireless headphones with top-end features and sound, but OK ANC

Shure Aonic 50 Gen 2: Two-minute review

Shure's Aonic 50 Gen 2 look the business. And not only that, they back up their not-here-to-mess-around aesthetic with Qualcomm's Snapdragon Sound support, so aptX Adaptive, aptX HD, regular aptX and LDAC are all here – aka all of the current top-tier wireless audio coding. 

But there's more! The Shure Aonic 50 Gen 2's bid for inclusion in our best wireless headphones guide culminates in a special USB-C port not just for charging. It means hi-res USB audio is also on the menu (look over here, iPhone 15 and Apple Music users!) thus completing a veritable banquet of connectivity options, from wireless Bluetooth audio pinged from your phone, older sources in a more traditional wired hi-fi system, right up to USB-C audio from your MacBook Pro at work. If that sounds good to you, add these headphones to your list. 

However, the star feature of these hotly anticipated second-generation Shure cans (let's be clear here, the three years and five months since the originals is eons in the world of headphone iterations) is Shure’s new spatialized audio technology. The feature provides three distinct modes: Music, Cinema, and Podcast. And the good news is that these are a delight across the board, offering oodles of separation and crispness to vocals during movies and podcasts especially, but unearthing extra sonic articles in even your heavy-rotation music playlists too. 

To stake a claim for the best noise-cancelling headphones currently on the market, Shure Aonic 50 Gen 2 feature advanced hybrid active noise cancellation. As you'd expect, mics inside and outside the earcup allow the Aonic 50 Gen 2 scope to fine-tune your auditory environment, but you can also help it along thanks to four selectable modes: Light, Moderate, Max, and MaxAware. 

For us, the performance here was just a shade under excellent. On the one hand, the clamping force is strong with this one (possibly even a little too forceful for those blessed with larger skulls) and levels of passive isolation are top-notch. But on occasion we found the more ambient-aware options (MaxAware aims to offer the best of both worlds – blocking unwanted noise and maintaining awareness of your surroundings) added warmth to our music and a marginal sweetness to the upper mids. Essentially, the overall efficacy of the noise-nixing here can be beaten by the class-leaders at the level.

Picking up on the comfort, at 340g they feel just a tad heavy over longer listening sessions, despite the ample padding. For reference, the Edifier Stax Spirit S3 weigh 329g they're comfortable for all-day use. OK, Apple's AirPods Max weigh 44g more than the Shures at 384g, while Sony's WH-1000XM5 are quite a bit lighter at 249g – so depending on what you're used to, there may be an adjustment period here. 

When it comes to sonic performance, Shure Aonic 50 Gen 2 is a set of over-ears for the EQ curious. There is very good sound to be had here, if you're prepared to work for it just a little. Those with neither the time nor the inclination to play with those presets might find the sound out of the box a little light on lower mids, treble-heavy and even a fraction cluttered timing-wise, albeit expansive and detailed. 

The ShurePlus Play app is your friend here and honestly, I'd go in to battle for this companion app – it is slick, easy to navigate and makes more sense than several offered by rival products. It'll even corral your music under one tab, for easy streaming across various services. Pairing is also a breeze and these headphones skip happily from one device to another thanks to multipoint connectivity that really works. 

In summary, the Shure Aonic 50 Gen 2 are solid all-rounders. If I'm nitpicking (and it is my job to do so), those who want perfect sound quality from the box may not have the patience for these headphones and the ANC is fine rather than fantastic – but those who love immersive spatial audio during movies, podcasts or playlists are well served here. And if you want USB-C hi-res headphones with the option to go wireless? They're an excellent choice.

Shure Aonic 50 Gen 2 review: Price & release date

  • Released in September 2023
  • Priced $349 / £349 / approx. AU$540

The Shure Aonic 50 Gen 2 arrived in the third week of September 2023, having been announced on August 31.

They are priced aggressively for the elite over-ear headphones sector. To explain, that MSRP is actually cheaper than the launch price of the inaugural April 2020 Shure Aonic 50, which were aimed very much at the upper end of the consumer market and evaluated accordingly at $399 / £359, around AU$580.

This clever new pricing strategy from Shure undercuts the asking fee of some of the best and most notable over-ear headphones in the business by a tidy $50 – see the Sony WH-1000XM5 ($399 / £380 / AU$649), the Bowers & Wilkins PX7 S2 ($399 / £379 / approx. AU$575) and the Edifier Stax Spirit S3 ($399 / £330 / approx. AU$640) for starters.

The Illinois audio specialist has put the Aonic 50 Gen 2 right in the way of the Sennheiser Momentum 4 Wireless too, which will set you back $349.95 / £300 / AU$549.95 too. Smart – if the performance is good enough.

Shure Aonic 50 Gen 2 review: Features

  • Excellent spatial audio processing options
  • Very useful EQ presets
  • USB Audio supports up to 32-bit/384kHz

Firstly, stamina: 45 hours is very good (although not as good as the 80-hour staying power of the Edifier Stax Spirit S3, granted, but the comparison is skewed since the Edifier headphones are devoid of ANC) and I can confirm that this battery claim holds true.

Shure Aonic 50 Gen 2 headphones are a walk in the park to pair, too. Multipoint? Easy – and once you get used to that fact that the physical buttons are all on the right earcup, altering volume, playback and ANC profiles works a charm. 

One lovely little perk here is PausePlus. Imagine you're listening to death metal at the office with Max ANC deployed and your boss approaches (just a random example, no reason). If PausePlus is toggled to on, simply pressing the multi-function button to pause the music also deploys ambient sound, so you can hold a polite conversation with your superior and pretend you were only listening to the latest episode of Revisionist History podcast.

Next up, Shure's Spatializer – no, nothing to do with turning vegetables into edible ribbons. In the app, under the device tab (see? It makes sense, it's a feature on the device) you can select spatial audio processing optimized for music, movies or a podcast. I found they brought all of these sources to life, adding depth, value and enjoyment to the whole testing process. 

The EQ presets are a similar story – in fact I suggest using both EQ and spatial audio liberally. There's a dedicated Equalizer tab, and although you can go manual if you want, Shure has sensibly opted to call its presets names such as Bass Cut, Bass Boost, Treble Cut and Vocal Boost. My particular favorite is Treble Cut for music, since I do find these headphones a little heavy-handed through the higher frequenciess, but the point is that Shure has bucked the trend of creating profiles for specific music genres (how often have you wondered whether 'jazz' is the correct preset for the acoustic mix you're listening to, or whether soft-rock is really the same as 'rock'?) and it's an excellent move. 

Now, ANC. It's acceptable. It isn't a complete bubble of silence. You deploy it by moving a physical slider all the way up on the right ear cup for ambient, or all the way down for ANC. But you can also open the app to select either the Environment Mode Level on a slider, or Light, Moderate, Max, or MaxAware ANC options. I was unable to perceive a lot of difference in the ANC options during the course of my testing save for MaxAware, which also filters in ambient noise. For softening the extraneous sounds of the office, they do a job – but the Bose Noise Cancelling Headphones 700 or Sony WH-1000XM5 still do that job a fair bit better. 

Call quality is aided by a "Hear myself on calls" toggle and it does exactly what it says on the tin, making calls feel a lot less like your head's stuck in a bucket as you speak. 

  • Features score: 4.5/5

Shure Aonic 50 Gen 2 review: Sound quality

  • Expansive and revealing separation and clarity 
  • Can come off treble-centric on occasion
  • Not the most musically cohesive listen

Kicking off with Ritchie Sacramento by Mogwai on Tidal (a FLAC file) with a wired USB-C connection to my Mac, the twinkling chimes and expansive ambient soundscape is pensive and more detailed than I remember it through lesser headphones. The driving beat underpins everything and as sonic articles jangle and dart between each ear, a rare talent for clarity through the mids is revealed.

Paolo Nutini's Loving You is a delight, with Nutini's textured voice held centrally among agile guitars and easy drums.

Switching to an Apple Music file on iPhone, Jamie T's Sticks 'n' Stones is energetic and immersive to the point that I feel Jamie and friends all congregating around me at Hampton Wick Station. It's here I notice the Shure Aonic 50 Gen 2's tendency to over-celebrate the treble though – and as a result, the mix can sound a touch disorganized and jumbled on occasion; the placement of each musical strand seems as if it relies on the frequency being played. Here, female backing vocal "ah"s come forward a little too readily when T's lyrics should be the star of the show, for example.

It's a relatively minor issue and one only noticeable in direct comparison against the likes of the Focal Bathys and Edifier Stax Spirit S3, but it's our job to notice. Otherwise, we're treated to a detailed mix with plenty of dynamic rise and fall through the mids and a decent serving of snappy bass weight. 

Deploying the Treble Cut EQ option is the panacea for the upper registers, but it really is worth switching out these profiles depending on your music. If you're someone who believes headphones should just sound good without having to lift a finger, you may not like this solution – and it's a fair point. 

  • Sound quality score: 4/5

Shure Aonic 50 Gen 2 review: Design

  • USB port on the right earcup, 3.5mm jack on the left
  • Design lies flat, but doesn't fold
  • Longer hair can get caught in the hinge points when fitting them

Do you miss foldable headphones – the kind that concertina up for easier portability? Well, you won't get them here. The large Shure Aonic 50 Gen 2's earpieces here lie flat in the same way that the Sennheiser Momentum 4 Wireless, Focal Bathys or newer Fairphone FairBuds XL do, and the hard-shell case is a little more svelte than the Focal's, but it'll still take up a bit of room in your bag – unless you want to use the strap to latch it to a carabiner on the outside of your backpack, perhaps. 

The build here is classy and the hinges rotate silently and at a glacial pace (be careful; the anchor point is towards the back of the headband and I caught my hair a few times) which is why it's a little strange that the headband itself is a little noisy if you need to alter the sizing. 

The padding on both the earcups and headband is ample and personally, I love that the physical buttons are all one earcup, since I'm right-handed, although those with larger fingers (or lefties) may find this a little fiddly. 

What is a little strange is the location of the cable ports, with one on each earpiece – but this is a relatively small issue. 

There's hardly any sound bleed; people on desks next to me couldn't hear my tracks at 50% volume in the office unless I lifted an earcup away from my head. On this, the clamping force is relatively strong; if you're running for a train you'll be glad of it, if you're relaxing in a comfy chair, perhaps not so much. There's no IP rating for water resistance here, so try not to wear them to the shower.

In summary, the Shure Aonic 50 Gen 2 are a handsome, sleek – if marginally heavy, at 340g – set of over-ears. They're not winning any design awards for originality, but the branding on each earcup is classy and if you prefer physical controls and sliders over touch capacitive functions (I do) you'll enjoy them. 

  • Design score: 4.5/5

Shure Aonic 50 Gen 2 review: Value

  • Spatial audio is a high-end option
  • USB-C audio connection adds flexibility
  • The merely acceptable ANC may not be what you want

First off, these headphones are not particularly expensive given their features and the price of competitors. That said, if you want the best ANC over-ears money can buy, spend it elsewhere, on the Bose Noise Cancelling Headphones 700, the Sennheiser Momentum 4 Wireless or the Sony WH-1000XM5. There is active noise cancellation here, and the presets are fine, but it isn't a class-leading experience. 

Buying headphones almost always involves a compromise somewhere (omission of a particular hi-res codec, poor call quality but great sound, lack of water resistance), but for the wealth of connectivity supported both with wires and without, the spatial audio profiles and the outstanding EQ tweaks, Shure's Aonic 50 Gen 2 are almost impossible to equal.

The battery level is more than sufficient at 45 hours, the build is classy, the companion app is excellent and the multipoint pairing experience has never let me down. 

The flies in the ointment? Occasionally the treble is a little forward in the mix and the ANC is a shade off excellent. Depending on your priorities, this either doesn't matter or is a deal-breaker. It's up to you.

  • Bulk of testing done using an iPhone 12, running ShurePlus PLAY app, firmware version 2.3.1.0
  • Tested over two weeks, listened against the Edifier Stax Spirit S3, Sennheiser Momentum 4 Wireless and Focal Bathys
  • Used on long walks on public streets, at work in a busy office, on a train, and at home
  • Listened to Tidal Masters, Apple Music, Qobuz and Spotify on an iPhone 12, a Sony Xperia 1 V, and via USB-C connection on MacBook Pro

To test headphones is to invite them into your life – how the case fits in your bag is just as important as how they slip onto your head. These cans became my daily musical companion – after a thorough run-in period. And just as Shure is a trusted name in audio, I now trust these headphones to work every day, regardless of how you're connecting to your music source, without fail. 

The Shure Aonic 50 Gen 2 accompanied me to work on busy weekdays (walking brusquely to the station; boarding a train and the London Underground; at the office) and walking along the blustery seafront on the UK coastline – a great way to test any wind-interference from mics during calls.

To check the audio quality across the frequencies, I listened to various playlists across various music genres (spanning everything from grime to classical) on Apple Music and Tidal, but also to podcasts and albums on Spotify – plus of course YouTube tutorials (on how to change my car's brake light, mostly) from my MacBook Pro. 

I’ve been testing audio products for over five years now. As a dancer, aerialist and musical theater performer in another life, sound quality and the user experience have always taken priority for me personally – but portability, security and comfort come a close second.
