About Earsonics

Tell me who doesn’t know about Earsonics? The brand has a long history when it comes to portable audio and they’re going forward and improving their products along the way. I myself have a personal history with the brand too. Once upon a time, I was using the Earsonics SM64 IEM with a Hifiman HM-601LE. Time really flies right? That was around 2013-2014.

The French IEM manufacturer is a well-recognized company with a good reputation among audiophiles. It was established in 2005 by Franck Lopez and the priority back in the day was to provide good monitoring solutions for the artists on stage. Then they became fan favorites with their unmistakable “house sound” and they proved themselves with many IEM models through the years. It is a very popular IEM manufacturer for audiophiles, especially for those who seek out something “different”.

We basically have reviewed everything from Earsonics over the years. The S-EM9, ES2 & 3, EM10, S-EM6 v2, ES5, Grace, and the list goes on and on including the older ones like the S-EM6, EM32, and the EM6 (Custom Version). Our last custom Earsonics IEM review was the EM64 stage monitor by Lieven.

My favorite Earsonics was the Purple model, which is still in our Best Universal IEMs list. I also reviewed their first hybrid offerings, the Blade and the Stark. The Blade is also on the recommended list. Last but not least, Yağız reviewed the Earsonics Velvet V2 HR Edition recently.

About Earsonics AERO

The Earsonics AERO is the company’s first-ever attempt in the TWS market. This is a fast-growing market with many opportunities for the brands that want to make a difference. As a result, the companies are releasing one TWS IEM after another and it’s like a flood. To be honest, only a handful of those sound really good, and I still think there’s a long way to go.

But when a company like Earsonics unveil a TWS IEM, my hopes are a little more than usual, since these companies give weight to sound quality with their boutique state. The same goes for Noble Audio and they managed to offer good sounding TWS IEMs, even their non-equalized presentations are not my cup of tea. I have the same expectations from Earsonics too.

The AERO has similar features as the other TWS offerings in the market:

  • Single Dynamic Driver
  • Bluetooth 5.0
  • Qualcomm aptX
  • AEQ Active Processing
  • Touch control
  • Vocal Assistant (Google Assistant, Alexa, SIRI)
  • Waterproof IPX4 protection
  • 21 hours of listening time (with the case)
  • 2 microphones (1 for the noise canceling on calls)

Design & Build Quality

The Earsonics AERO has an Apple-style stick shape, but it has a distinct Earsonics touch on it. The color is a matte black one with a design that is reminiscent of their latest hybrid series IEMs. It in fact is very suitable for office and work environment with a full black sleek look. I also liked the fact that they kept the design and looks consistent with their latest offerings. Especially those stripes under the microphone area are a great touch.

Another thing that is typically Earsonics is that the earpiece area has an angular design instead of being round. That is a very Earsonics thing as their plastic shells from the past IEMs have that feature. So although Earsonics went for a stick-style TWS, they managed to put their touch on it. It’s not another copy-cat. Details matter. In terms of experience, the design is user-friendly and comfortable to use and wear. This is the first time that I test a stick TWS, but I have to admit, it’s much easier to remove the earpieces from your ears this way.

Earpieces have a 3 part design that is assembled together. The build quality is very good but not extremely good. This is an all-plastic design so you shouldn’t throw them or toss them around. However, for normal operations, it has a good build quality without a doubt.

Yet, I can’t say the same for the case. This is a common problem in my eyes when it comes to TWS IEMs and I think companies should look more into that. Especially the lid of the case doesn’t feel very sturdy. The same thing is present with the Noble Falcon, but they improved the case with a whole new design with the Falcon 2 and the Falcon Pro. Therefore I think Earsonics should improve the case in the future. After all, this is close to premium pricing when it comes to TWS IEMs.

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.
