Earsonics AERO Review

User Experience

The Earsonics AERO offers a very nice user experience with touch (maybe I should say “tap”) controls and pleasing functionality. The fit is excellent and very comfortable with the AERO, and fitting them to your ears and taking them off is extremely easy to do. It’s a very flush fit and the angular design is actually thought out very well. The earpieces sit in your ears with a good grip so it’s a very comfortable and dependable TWS IEM for sports and activities. The isolation is very good too. You just need to pick the right tips. Earsonics provides 3 pairs of silicons.

In terms of calls, I found it better than the other models I’ve tried and I think the stick design helps for that matter. The actual phone still has a better microphone than the IEM itself, but unless you’re in a very busy environment, you can comfortably make and receive phone calls. I mostly used one of the earpieces alone for phone calls, which is a nice feature as well; you can use a single earpiece.

The operation is also very easy and user-friendly. You use the “touch panels” for issuing commands, which are located on the “ES” logo area. When the music is on, a double-tap to either earpiece stops the track. Another double-tap makes the song continue. For calls, you tap once for answering and hanging and double for rejecting. Controlling the volume is done by a tap the right side once for cranking up. For lowering the volume, you need to tap once to the left. If you want to skip a track you need to touch the right earpiece for two seconds. For the previous track, you do the same to the left side.

Powering on is performed by touching the panel for 3 seconds. For switching off, you need to do the same for 5 seconds. So you don’t have to place them back in the case of switching them off. Overall the AERO performs well without any bugs and the operation is very simple. Earsonics doesn’t offer special software, but I don’t think it’s needed.

Sound Quality

I don’t have big expectations from TWS IEMs in any case, and I don’t think they can replace the classic IEMs in terms of sound quality, not yet anyway. However, after listening to many pairs of TWS models, I think that the most important factor is overall balance and cohesiveness. Most TWS offerings give either too much bass or too much treble. Most of them are uncontrolled, tuned for popular music types which are not necessarily high-quality recordings.

So I didn’t know what to expect from the Earsonics AERO. Part of me said that this is just another V-shaped TWS for electronic music, and part of me said that it might not have any resolution and separation like others. However, Earsonics has surprised me with the tuning. The AERO is a very coherent, controlled, and technically capable TWS.

Bass

The bass is the most surprising part about the AERO for me. Well, finally a TWS which is not trying to be the ultimate bass monster for the sake of the crowd. This one has well-textured, nicely controlled bass with a good mid-bass body (wow, they can make these after all!). So for once, it’s not all about the sub-bass rumble.  I’m really glad that Earsonics have paid attention to the mid-bass area as well, for defining the instruments and notes.

The bass has a good kick, enough rumble for electronic music with also enough control and quality for classic genres. Turns out Earsonics has found a nice balance in lows. The AERO becomes an all-around TWS this way. Do you need bass? You have it for sure. Do you need a nice definition, sufficient enough bass levels with good control? You have it too. It all depends on what you’re listening to. That’s why I particularly remarked about having no need for additional software. Because this one doesn’t need any EQ for a better and more balanced response. It’s already well-balanced itself.

Mids

The mids are not recessed with the Earsonics AERO, so again it’s not a typical TWS in terms of mids either.  For the lovers of vocal-oriented genres, instrumental music or Jazz, or Classical, the AERO performs very well with good definition and layering. The resolution and dynamics in this area are also very good. It has good tonal accuracy as well. If you like listening to vocals, then you’ll be even more impressed.

The resolution and transparency are on ideal levels and I don’t expect it to better for a TWS IEM. That’s the main thing. Because most TWS IEMs sound quite terrible for me, the likes of Falcon Pro, Momentum TWS2, and Earsonics AERO shine among others.  This is as close as it gets for an “audiophile TWS”. Dynamics are good, fidelity is nice with a very resolving nature.

The note size is very good and the lower notes of instruments are impressive. So technicalities-wise this is a very capable TWS IEM that has the potential to surprise even hardcore audiophile folk. There’s no doubt that it’s great for classic genres unlike many TWS models in the market. For fidelity alone, it is indeed one of the best choices in the market at this time.

Treble

The treble is unaggressive, very well controlled, and very detailed. So again, this is not a piercing treble response with an aggressive approach. The treble is easy going, smooth, yet very transparent and resolving. The thing with the Earsonics AERO is that there’s nothing over the edge, nothing too much. It’s just very well balanced and coherent.

The treble extension is very good and there’s good clarity. High are effortless with good space and air. It’s nicely definitive but there’s no tendency to sibilance or any sorts of peaks. Once again, the AERO manages to impress with the resolution, detail, and definition without sounding harsh. Many TWS IEMs have massive treble peaks or treble focus. AERO, on the other hand, gives importance to the whole of the spectrum, not missing anything but not forcing anything either. The treble is not muffled but if you’re looking for a very sharp treble, it’s not present. However, you will certainly not miss any detail or resolution.

The review concludes on PAGE 3 with technical performance and comparison.

A keen audiophile and hobby photographer, Berkhan is after absolute perfection. Whether it is a full-frame camera or a custom in-ear, his standpoint persists. He tries to keep his photography enthusiasm at the same level as audio. Sometimes photography wins, sometimes his love for music takes over and he puts that camera aside. Simplistic expressions of sound in his reviews are the way to go for him. He enjoys a fine single malt along with his favourite Jazz recordings.

    If you like these and don’t typically like the digital sounds of most TWS, try the Samsung Buds Pros. I can’t tell you how many times I have to take them out because I thought I heard something coming from the outside, only to find out it was coming from the earphones. They are that clear and natural.
