Shure is no stranger to high-performance audio. The company's in-ear monitors (IEMs) and microphones have been the first choice of musicians and audio professionals for decades. But when it comes to the true wireless earphone market, Shure has only just stepped into the ring with its $ 199 Shure Aonic Free. Was it worth the wait? And how do these new buds compare to products from more established brands like Sony, Jabra and Apple? Let's check them out.
A larger set of buds

Let's talk to the elephant in the room: The Shure Aonic Free are big. They use a very similar design to Sony's previous flagship, the WF-1000XM3, which places the electronics, battery, and other goodies in a diamond-shaped gondola that sits fairly prominently outside your ear.
Shure's design is even bigger than Sony's, making the Aonic Free one of the biggest buds we've ever tested. Fortunately, these nacelles look pretty sleek, with a relatively thin profile and a satin gunmetal finish that gives the plastic a high quality, sophisticated look. If you really want to get noticed, they are also available in red. But despite their size, they are also remarkably light and in fact weigh a gram less than the Sony XM3.
There's a lot of precision and detail, especially in the mids and higher frequencies.
And while there's no denying that these buds are really big, the design has two distinct advantages. First, with all of the bowels of the buds outside of your ear, the part that actually fits in your ear is tiny and extremely comfortable. Shure uses memory foam earplugs instead of silicone, which increases comfort by reducing pressure points.
Not everyone loves the sometimes squishy feel of memory foam, but I'm a huge fan. Once inserted, the fit is very secure, but it won't withstand vigorous activity, as well as buds designed for this purpose. Expect to need regular readjustments as you walk. In fact, you might want to avoid using the Aonic Free for exercise: they are some of the only earbuds on the market that do not offer official protection from water in relation to an IPX rating.
Second, the large outer gondolas make pressing the multifunction button located on the top edge very easy. Accidental presses are almost completely eliminated, and you probably won't accidentally remove an earbud while using these buttons.
The Aonic Free comes with an equally large charging case to match the large buds. It absolutely dwarfs the tiny package of the AirPods Pro case, and I doubt a lot of people will think of it as pocket money. It also lacks wireless charging, which is an unfortunate shortcoming at this price point. Nevertheless, it is robustly built, the lid can be easily opened and closed using a large study hinge and the Aonic Free is really easy to plug in and out of the charging sockets.
I like the sound
Simon Cohen / Digital Trends
In keeping with Shure's reputation for stage and studio equipment, the Aonic Free has a neutral and very clear sound signature. There's a lot of precision and detail, especially in the mids and higher frequencies. A track like Dire Straits ’Six Blade Knife and Mark Knopfler's unmistakable Stratocaster work becomes a haptic experience – you can almost feel the strings under his experienced hand.
The bass reproduction is strictly controlled, is only displayed when necessary and never overwhelms the other frequencies. Such a conservative approach to bass can make the Aonic Free sound cold when you're used to headphones or earphones like the Sony WF-1000XM3 or XM4.
This is how things sound right out of the box. But the Shure Play Companion app can completely change the personality of the Aonic Free with its EQ adjustments. Shure gives you seven presets to play with, including Bass Boost, Bass Cut, Vocal Boost, and Loudness, but if you really want to get the most out of the Aonic Free, you need to try the manual EQ option. Here you will find a graphic EQ that can be adjusted more precisely than I have ever seen it before. You get four control points on a frequency spectrum from 20 Hz to 20 kHz. Each of them can be raised +/- 10 dB in 0.5 dB steps, and you can even adjust their bandwidth from 0.2 octaves to 4 octaves in 0.1 octave steps.
If all of this is Greek to you, suffice it to say that this is an unmatched level of EQ control for a set of true wireless earbuds, and those who love to mess around with the sonic weeds will love it.
It's worth noting that the Aonic Free doesn't generate as much volume as a percentage of some other well-respected earbuds. In other words, at 50% volume on my iPhone, the Aonic Free were significantly quieter than the Jabra Elite 7 Pro or the Technics EAH-AZ60. I don't see this as a problem – they can still get really loud – but you may find that you have to run these earbuds at a higher setting than you are used to.
It's also worth noting for Android users that Aonic Free supports the aptX codec, which can be helpful in situations where audio delay (latency) is an issue.
Total control
Simon Cohen / Digital Trends
The Aonic Free do not have Active Noise Cancellation (ANC), but thanks to these foam earplugs they are excellent at blocking outside noise passively. There have been a couple of times when I felt like ANC was blocking a bit more, but not many. What they have is a very good transparency mode that you can set in the Shure Play app to let in little or a lot of the noise around you. In fact, at the maximum setting, it amplifies some of these sounds, so some careful adjustment is required.
I love that Shure has built in a feature called PausePlus that allows you to automatically turn on transparency mode when you pause your music. With too many earbuds, you'll have to pause first and then switch to transparency, which can be annoying when someone tries to talk to you.
The Shure Play app also gives you complete control over the multi-function buttons. You can assign up to three different commands per earbud, including play / pause, skip forward / backward, transparency on / off and access to the voice assistant. In addition, you can choose whether you want to control the volume with a fourth gesture. It's a bit awkward, admittedly – you have to press and then long press – but it's a handy option nonetheless. The only thing Shure left out is wear sensors, which can automatically pause if you remove one or both of the earbuds – another surprise considering how many other earbuds come standard with them at this price point.
Your phone call options include muting the microphone and switching between two calls, both of which are rare features. You can also use each earbud independently for music and calls.
Avoid the wind
Simon Cohen / Digital Trends
Call quality on the Aonic Free can be excellent, but you need to avoid windy or very noisy situations. The microphone does a great job of capturing the full tone and resonance of your voice, with little to no distortion, but struggles to maintain that quality under adverse conditions. They're definitely not the earbuds you'd want to use on the phone while you bike through heavy traffic, but they will work admirably on Zoom calls or anywhere you find relatively calm conditions.
Speaking of Zoom calls, the Aonic Free are the first headphones I've come across that can automatically turn on a red LED light when you're on the phone to let others know that just because you're not speaking, you aren't yet to be interrupted. It's a look back at the early days of Bluetooth, but I think it's brilliant – all true wireless earbuds should have a similar option.
More performance please
Simon Cohen / Digital Trends
Shure claims that the Aonic Free can last for around seven hours on a single charge, and as far as I can tell, that's correct when you're listening at 50% volume. But as mentioned above, because these Buds run quieter than other models, you'll likely hear at 60% or more, which will reduce battery life a bit.
I agree – six to seven hours is still enough for most people. But what I can't understand, given their huge charging case, is why you can only charge the earbuds twice for a total of 21 hours of playtime? If the Aonic Free were really small – say, AirPods Pro small – I'd happily accept that (although even the AirPods Pro have a longer total time of up to 24 hours), but the Aonic Free have no such excuse.
Our opinion
Although the Aonic Free are larger than most true wireless earbuds, they are very comfortable and offer exceptionally clear and detailed sound. For the discerning listener, this may be worth the price of admission, but given the many features that are lacking at the price, most people will likely be happier with other models.
Are there any better alternatives?
When it comes to sheer clarity, attention to detail, and EQ control – that so-called studio sound – you will hardly find a better set of true wireless earbuds, even if you are spending well over the price of $ 199 on Aonic Free. But considering how many features Shure has left out, here are two options worth considering:
$ 200 Jabra Elite 7 Pro: At the same price as the Aonic Free, the Elite 7 Pro has it all: Great sound, great ANC, great transparency, tons of customization options, long battery life, wireless charging, and an IP57 rating that makes it effectively waterproof. Oh, and they're much smaller too. Audio purists will still prefer the incredibly precise sound of the Aonic Free, but I also think the Elite 7 Pro sounds pretty good.
230 $ Technology EAH-AZ60: For a slightly larger investment, the AZ60 offers fabulous ANC and sound quality that rivals the Aonic Free, but with a slightly warmer standard signature that will appeal to people who don't love the sometimes overly accurate Shure sound. The Technics also have Sony's LDAC codec for wireless hi-res audio and Bluetooth multipoint to connect two devices to your earbuds at the same time.
How long will they last?
Given their total lack of water protection, this very much depends on how careful you are with the Aonic Free. The build quality seems to be excellent, however, and Shure backs it with a two-year warranty, which is unusual in this product category. That might be a good sign that they'll be better off in the long run, but like all true wireless earbuds, it's likely that decreasing battery life is what is keeping them from still being in your audio arsenal 10 years from now.
Should you buy it?
Yes, but only if you're looking for what Aonic Free has to offer – a highly detailed, precise, and customizable sound with very few other bells and whistles. For everyone else, you can find better options for the same price or less.
