I own the AKG K501s and the Sony MDR 7506 (same as V6). Until a few days ago I had not heard the HD-600s. Well, after close to 3 years on the job (!), I found that one of my colleagues has an interest in headphones, and he owns the HD-600s. Sure enough, we set up a quick comparison. Since this...

Ok, here is the question. The light comes on OK when I use the AC adapter, but only on the bottom of the display (looks like 6 little LEDs). I remeber when I just got it, there was light coming from the top of the display also (but I might be mistaken). How is yours?

Hi everybody, Based on the recommendations from this forum I bought the Sony MDR 7506 and I am quite happy with them. I have a problem though: when I listen to them through my Yamaha HTR 5140 receiver, which has a headphone output impedance of 300 ohm, there is pretty loud hiss at low volume...
