#Koss UR20 has disappointed me. I've read so much praise about it. And there's a digital #piano picture on the box, so I gather they target electronic instruments' users as well. Can't say anything about that, as I don't own an electropoano. However, a real piano off of .flac recordings sounds dull and unclean in this headset. And then my head starts actually hurting. Such a shame.

So far, nothing sounds better than my #Sennheiser CX180 plugs which I've had for at least 8 years. Weird but true.
