Got a set today, and had the chap at the shop fit it for me (he's done heaps of them). Everything seems fine except the sound. I've only tried FM radio so far, but it was very ordinary. Definitely not too loud like some on another forum have found, and virtually no bass at all. Also a bit of distortion is seemed from what I could hear. That bad that I'm tempted to see if I can get a refund I'll try on mp3 tomorrow (what I intended to use most often anyway), and if it's OK, I'll keep it. Anyone else had any issues?
