Earsonics Corsa Review


Earsonics’ house sound is quite obvious and apparent with the Corsa on first listen. It has apparent darkness and vividness in its sound. I found some similarities to the ES5 in terms of that darker Earsonics tonality.

The sound overall is pretty balanced and cohesive. However, whether you will like the Corsa or not would depend on your personal preferences. It has good technicalities, but the presentation has a warm nature with a dark approach. Nevertheless, this model has much more price/performance than the Stark in my opinion, just like the Blade.


The bass in the Corsa is not as rumbling as the Blade or Stark, and it doesn’t have that punch and kick. But it provides a very nice mid-bass quantity that feels quite warm and meaty. The sub-bass rumble is not that apparent compared to the Blade and Stark, and the mid-bass area is a bit more apparent when compared. The bass control is good enough so it doesn’t sound very bloated. However, I need to say that it’s on the edge on that part. A little bit more mid-bass would’ve made the presentation congested and muddy. I wouldn’t pair the Corsa with very warm or bass-heavy sources or equipment. That would most probably result in a bloated bass presentation.

Lows have good texture and resolution and what I liked the most is the tonality of the mid-bass. It presents a great foundation for instruments’ lower notes. But as I said, source matching is important here. The bass is not as controlled as the Blade, and decay is not as fast.


The mid-range is well defined as it provides a nicely focused mid-range with good enough room and space. Thanks to this spacious mid-range, the timbre is very nice to my ears with good breathing room for the instruments and vocals. Presentation-wise the mids are warm and they sound quite organic with good resolution. Tonality is quite good when it comes to guitar and sax tones. The mids overall have good body and fullness. So in its own warm and organic presentation -and also considering the Earsonics’ house sound- this is a fairly good mid-range performance.

The Corsa might not sound very transparent to your ears though, as it doesn’t have the ultimate fidelity or clarity. However, from the resolution standpoint alone, the Corsa is pretty nice for its price and presentation. Its unique tonality also can impress you in terms of guitar and sax notes. Because for some odd reason, it presents the saxophone in a very unique way in Jazz songs. It doesn’t mean that this is the correct timbre, but it’s nice nevertheless.

Overall, this is the best area of the Corsa in the whole spectrum. If you like a creamy, musical, and full mid-range presentation, the Corsa is your IEM, especially if you prefer vocal-oriented songs.

Treble is good and under control at all times with a good definition. However, the extension is not the best and the treble doesn’t have the best resolution. You may want a more open and clean treble presentation with more brightness. You won’t find that in the Corsa so be aware. Other than that highs have good positioning and resolution. They’re not very transparent though, and not very very detailed. They’re slightly darker and thicker than most IEMs out there.

So the treble performance is not a strong suit of the Corsa. If you’re a treble-head, or if you just like to have a crisp treble response, the Corsa may not suit you. This is definitely not the most detailed treble presentation. The Corsa doesn’t really excel at treble when you compare that to the rest of the spectrum. It’s nice in the bass, very good in the mid-range but not great in the treble.

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.
