Input:
Absolutely excellent headphones for the price. Crystal clear highs / excellent low range response as well. Lightweight, comfortable and they stay comfortable after wearing for long periods of time. The only negative aspect that I could mention is that even thought the bass response is really prominent, the bass starts to deteriorate at higher levels (probably due to the fact my receiver is rated at 170 watts per channel).  However, one must remember that hearing damage WILL occur at higher listening levels (hence, I really should not be listening at higher levels myself....do as I say, not as I do!!) However, my listening preference is full bass/treble.  Would I recommend this set to a friend, most definitely!
