Shure AONIC 215 True Wireless Gen 2 review

The AONIC 215 True Wireless Gen 2 are Shure’s latest true wi-fi earbuds. It’s a mix of two merchandise, the Shure True Wireless Secure Fit Adapter Gen 2 (god these names are terrible) and the entry-level SE215 earbuds. It is the most affordable of Shure’s TWS vary, the place the adapters stay the identical however the linked earbuds get extra superior as you go up the worth ladder.

Because of their modular design, the adapters will be linked to some other wired earbuds that use an MMCX connector. Similarly, the offered SE215 earbuds can be eliminated and hooked up to a cable with an MMCX connector and utilized in wired mode. While the latter state of affairs does defeat the aim of getting this product, you could possibly ostensibly get it from time to time improve simply the earbuds sooner or later.

(*215*) for now, I will likely be reviewing the AONIC 215 True Wireless Gen 2 — or AONIC 215 TW2, as I’ll be referring to them going ahead — as a single product. It is kind of unconventional in comparison with a lot of the different stuff that comes via right here however that is what makes it so fascinating.


The AONIC 215 TW2 are available in a typical over-the-top Shure packaging that’s 4 instances bigger than it must be. I observed this with the AONIC 50 as properly however at the least in that case the headphones had been fairly massive and necessitated a big field. In the case of the AONIC 215, Gen 2, a lot of the field is simply empty house.



Inside, you get earbuds hooked up to the adapters, the charging case, three pairs every of silicone and foam ear ideas, and a software for eradicating ear wax. A brief USB-C cable can also be offered for charging.


Being a two-part design, let me first begin with the design of the wi-fi adapters. The True Wireless Secure Fit Adapter have been improved over their predecessor launched only a 12 months in the past however from the surface, you possibly can’t actually inform the distinction.

The adapters have rubbery stalks that sit over your ear and a bulbous unit that hangs on the again. It’s a clumsy design from an aesthetics perspective and easily hasn’t grown on me, though I by no means must see it whereas carrying them. It is, nonetheless, much less visually cumbersome than one thing just like the Fiio UTWS3 and appears a hell of quite a bit much less like a listening to support than the Fiio mannequin.

The spherical bit on the finish of the adapter includes a single massive button that’s stupidly straightforward to function and might be my favourite factor about this design as I’m so bored with utilizing annoying tiny buttons or much more annoying gestures on TWS earbuds. The button is so massive that though the unit sits behind your ears, not as soon as did I’ve any difficulty hitting it on the primary attempt.

The adapters characteristic a normal MMCX connector on the opposite finish, which is without doubt one of the two connectors utilized by wired earbuds (the opposite being 2-pin). All of Shure’s earbuds use MMCX so it is smart they went with that on their adapter however there are many earbuds in the marketplace that use MMCX connectors.

Of course, that is not a priority right here, because the adapter does include the SE215 pre-attached on this case. The SE215 earbuds have a small physique and a cable-up design widespread for skilled earbuds. Because of the MMCX connector, the earbuds can spin freely whereas hooked up.

The AONIC 215 TW2 are additionally IPX4 rated, which implies they’re examined for water resistance.

Lastly, there may be the carry case, which additionally prices the adapters. It’s fairly large, which is to be anticipated contemplating the dimensions of the adapters. The case additionally must be large to accommodate any earbuds that you’ll have hooked up to the adapter. While the AONIC 215 TW2 aren’t massive, Shure provides this identical case even in the event you simply get the adapters individually.

Placing the adapters contained in the case is not as straightforward as plopping your AirPods inside their case, as you must plug in every adapter fastidiously and ensure it has hooked up to the charging pins. You can connect both adapter on both facet as they’re symmetrical. This additionally provides some room in case your hooked up earbuds are too massive and will not match face down so you possibly can simply swap them round and have them be face up.

The case closes with a zipper as a substitute of a magnetic latch. The lid has an over-engineered optical tube to switch the sunshine from the LED contained in the case to the surface when closed.

On the underside of the case is the charging port, which sits going through ahead for some motive. There’s additionally a button to see the cost standing of the case. Unfortunately, regardless of its dimension, the case would not assist wi-fi charging.


The AONIC 215 TW2 are a reasonably comfy pair of earbuds. The precise earbuds themselves are fairly small and match comfortably even inside my small ears. Coupled with the froth ideas, which come pre-installed, I used to be in a position to put on them for hours at stretch with out feeling any discomfort.

The adapters, nonetheless, are inclined to get in the best way a bit. They occupy house above and behind your ears and this proved to be a little bit of a trouble whereas carrying masks. Also, whereas I do not put on spectacles, I wasn’t too keen on how my sun shades needed to sit on prime of the adapter. Add a masks on prime and all of the sudden there are far too many issues vying for house in restricted actual property.

By and huge, I’d nonetheless classify the AONIC 215 TW2 as comfy. The difficulty is with the form-factor typically and though Shure has tried to mitigate it to some extent by making the stalks skinny and inserting all of the electronics contained in the rounded portion, it can by no means be as small and comfy as one thing just like the AirPods or Galaxy Buds.

Software and options

The AONIC 215 TW2 characteristic Bluetooth 5.0 connectivity. They assist SBC, AAC, and Qualcomm aptX codecs. There is not any multi-device pairing performance.

The earbuds interface with the Shure Play app, accessible on iOS and Android. Through the app, you are able to do issues like adjusting how the controls on the facet work, updating the firmware and adjusting the EQ. The app can also be a music participant and any native audio recordsdata you’ve gotten will be performed via it.

The app does the annoying factor that some Bluetooth companion apps do the place they lose reference to the system whenever you droop them for too lengthy. This would not actually have an effect on the performance with the headset as any adjustments you make on the app get saved on the earbuds however it does trigger you to attend for the app to provoke the invention for the earbuds the following time you open it.

The app additionally features a transparency mode though the earbuds don’t characteristic lively noise cancelation. Even with out ANC, the transparency mode on the AONIC 215 TW2 works the identical as on some other system. Shure additionally helps you to modify the power of the characteristic.

One neat possibility lets the earbuds routinely have interaction the transparency mode whenever you hit the pause button and turns it off whenever you play. However, for this to work, you must pause and play from the buttons on the adapters and never out of your paired system. Also, on one event, the transparency mode simply turned on after a playlist ended, which looks as if a bug because it solely occurred as soon as.

It’s in all probability price mentioning that attributable to their design, the earbuds haven’t any type of in-ear detection characteristic to routinely pause whenever you take away them. You must manually play and pause each time, like an animal.


Audio high quality

The Shure AONIC 215 TW2 are a great-sounding pair of earbuds. That in all probability should not come as a shock because the core part of them, the SE215 earbuds, are offered as wired earbuds. With wired audio, there may be nowhere to cover. You cannot simply choose bargain-basement drivers, slap a DSP on them, and get away with it as you possibly can on wi-fi audio. The 215 have been out for over a decade now and proceed to be on sale, in order that they have to be doing one thing proper.

The sound profile of the SE215 is fairly acquainted, which is barely heat and a bit darkish. The 215 put extra emphasis on the higher bass and fewer on the treble area.

Shure AONIC 215 True Wireless Gen 2 review

The bass response is extra biased in the direction of the mid and higher bass area. There is a slight bump right here, which provides a touch of boominess to the bass however by no means will get overbearing. The decrease bass, nonetheless, is a bit toothless and would not fairly have the slam and influence that you simply’d need. The general bass response is heat and punchy however missing a few of that excessive low-end rumble.

The mid-range efficiency is excellent. The decrease mids do have extra vitality than anticipated as a result of residual bump from the higher bass carrying over. This leads to a slight nasal high quality to the notes on this area however it’s not too distracting. The remainder of the mid-range efficiency is kind of good and even.

The treble efficiency is much less spectacular. The decrease treble popping out of the mid-range is respectable however it loses quantity within the mid and higher treble ranges. This dulls the general presentation and takes a few of the vibrance and vitality out of the audio, resulting in a darker tonality.

Depending upon the music you take heed to, this will or could not attraction to you. Listening to actually shiny genres was surprisingly pleasant, because the tuning of the drivers takes a few of the edge out of the sibilance and harshness. On the opposite hand, well-recorded tracks sounded murkier than meant.

In phrases of technicalities, the 215 are spectacular at element retrieval. Even with wi-fi audio, there’s a good quantity of element and determination current within the sound. The softer high-end dulls a few of the element however there isn’t any denying that the 215 drivers listed below are nonetheless doing a vastly higher job than virtually some other wi-fi earbud.

The 215 even have actually good imaging though the soundstage is unexceptional. Both are as soon as once more affected by the softer high-end because it restricts a few of the airiness and spaciousness of the sound.

I used to be not in a position to check the adapters with a distinct pair of earbuds as all the opposite wired earbuds I’ve use the 2-pin connector quite than MMCX. However, there are many MMCX earbuds on the market from varied manufacturers, which makes these adapters engaging if you wish to improve sooner or later or simply swap round for various use instances.


The microphone efficiency is mediocre. They are positive for the occasional voice name however I might not suggest these in the event you make a number of voice calls or if name high quality is essential to you.

The AONIC 215 TW2 have good latency efficiency for watching content material. While enjoying again movies on YouTube or Netflix, the audio latency was low sufficient to not be noticeable.

For gaming, the latency was fairly noticeable, even in informal video games. I might not suggest these for gaming.

Noise cancellation and transparency

The AONIC 215 TW2 don’t characteristic lively noise cancellation. However, the passive noise isolation is terrific. It’s typically tough to listen to somebody speaking to you even when they’re standing subsequent to you and ambient noises just like the air conditioner or the TV within the subsequent room are all however inaudible. The passive isolation is healthier than a few of the lively noise-canceling earbuds on the market and the credit score to this goes to the prime quality silicone and foam ideas that come bundled with the earbuds that create a incredible seal.

Thankfully, the earbuds do provide a transparency mode. It’s not essentially the most natural-sounding transparency mode I’ve heard however it will get the job performed.


The AONIC 215 TW2 had dependable connectivity efficiency in my testing. Not as soon as did connection break and even briefly falter. My testing was performed utilizing a OnePlus 9 Pro utilizing aptX and an iPhone XR utilizing AAC.

Battery Life

The AONIC 215 TW2 have a rated battery lifetime of 8 steady hours of audio playback. Shure doesn’t point out what codec was used to realize this determine however it’s often SBC or AAC.

Shure AONIC 215 True Wireless Gen 2 review

I did my testing utilizing the aptX codec and obtained 6.5 hours of steady use. That’s not too shabby and it is probably you will get the total 8 hours in the event you used SBC or AAC.

I additionally examined for the way lengthy the battery lasts after a fast 10-minute cost from flat. Shure doesn’t make any claims for this however I did handle to get 3 hours of steady use, which is fairly good.


The Shure AONIC 215 True Wireless Gen 2 (sigh) are definitely essentially the most fascinating TWS earbuds I’ve examined. The modular design means you could possibly simply improve the earbuds sooner or later whereas retaining the adapters, one thing you can’t do with different earbuds.

(*215*) what actually units them aside is their pedigree. The adapters are designed to scale up from the SE215 to Shure’s costlier and way more spectacular fashions. Because the adapters stay the identical throughout the vary, they needed to be technically spectacular, which they’re.

Shure AONIC 215 True Wireless Gen 2 review

Moreover, the SE215 are not any slouch. The 215 have been round for over a decade at this level and have a fame for providing nice sound regardless of being the entry-level mannequin in Shure’s lineup.

When you mix these two merchandise, you might be sure to get one thing that routinely rises above the mediocrity that one usually sees within the Bluetooth audio house. The AONIC 215 TW2 carry out like an amazing pair of earbuds that simply occur to be wi-fi. And that is Shure’s entry-level mannequin; all they needed to do was pair their least expensive wired earbuds with their wi-fi adapter they usually immediately sound higher than 99% of the Bluetooth earbuds in the marketplace.

Other points of the AONIC 215 TW2 are additionally fairly good. The massive buttons on the adapters are extraordinarily straightforward to make use of. The battery life is sweet, the passive noise isolation is incredible, and the app affords good customizability. And whereas the design does get in the best way of glasses and masks, the earbuds are nonetheless extraordinarily comfy to put on for hours.

At $229, the AONIC 215 TW2 are on the costly facet. You can definitely get extra options for much less cash, to not point out a extra standard design that many would like over the considerably clunkiness of the AONIC 215 TW2.

(*215*) in the event you ask your self what you are in search of in your wi-fi earbuds and if the reply is simply audio high quality, then the AONIC 215 TW2 is what you have to be getting.
