Got a friend in Indonesia who sent some graphs my way. Based off preliminary measurements, it can be assumed that it's more-or-less in line with the measurements that my IMM6 produces.
Avara is a local Indonesian CIEM maker focusing on affordable customs for the masses.
Avara AV1
Avara AV2
Avara AV3
Notes and impressions (not mine)
- The AV1 has a distinct lack of treble on first impression. It has a good midbass presentation that is definitely faster than the SE215. Vocals carry decent weight as well but it lacks extension and makes female vocals sound dull and muted. Treble presentation is equally dulled due to the rolloff post 5k. Not recommended even at its $165 price point, except only for the most desperate.
- More treble is immediately apparent on the AV2 compared to the AV1 whilst keeping the bass quantity. Mids aren't necessarily recessed but there's a jarring difference of amount of lower mids and upper mids, making the female vocals sound thin. The bass is pretty linear and enjoyable but the vocal timbre was off as mentioned earlier. Treble has enough energy but doesn't feel natural. Still not so worth it at $235 honestly.
- The AV3's bass has decent enough kick and low-end extension. The mids has nice enough body to it that vocals sound natural, both male and female. Good top-end extension that brings more airiness to the sound. Treble is quite polite while keeping the quantity enough to satisfy, and presents an accurate timbre as well. A solid recommendation at $290.
