I use it for the past six months, to play drums.
production: it is a bit plastic, but very léger.le cord is light but so far no problem with.
Comfort: I find it very comfortable.
Sound: I originally used to work the pieces with a CD, or as a return. The sound is fairly balanced in order to distinguish the subtleties of the songs. It isolates the battery enough to keep a proper volume. I use it even now not connected to avoid the extreme volume of the instrument.
We have to see the aging of the longer term, but for now it does not move.
Given the price compared to competition, I would do the same choice without any hesitation.
