Consistantly Faulty, May 14, 2008
By Lifeshard from Salt Lake City, Utah

(read all my reviews)

I ordered these to use at work with very low volume, and the files I listen to are almost completely stripped of all low frequencies. The first sets right speaker put out at ton of distortion and static so I sent it back and had it replaced. The replacement set had an identical problem in the left speaker. The result of this is constant static when your listening to anything, and I haven't even tried them in a high volume high bass situation. Do not bother with these headphones if you are looking for an item that will stand up to very bassy music, as they didnt even hold up to low volume phone call recordings.

She loves it very comfortable sounds great! It's much better than the ear plug phones that came with the MP3 player & would recommend it for any audio device!
