Meh

 

I am trying to reduce wire clutter on my work desk, so these fit the bill, but I'm not terribly impressed with them. Minus 1 star for the mediocre sound, and another for the poor battery life.

Very comfortable, no signal degradation at other side of the house from the transmitter

Sound is *okay*. The bass is a bit weak and muddy compared to the wired v900hd, but that's to be expected from wireless I guess ; The included battery pack has an 8 hour discharge, but takes *15 hours* to recharge. You will need an extra pair of...

great product unless voume is important

 

I found the maximum volume to be less than what I would like but it is certainly enough to hear tv programs etc. If you like your music loud look elsewhere. I love these cans in all other respects however. A very class product in all other aspects.

Fair Deal

 

I've only had these headphones for a few months but so far I can say I'm satisfied with them. Sound quality is alright. There is a little bit of feedback if the headphone volume is up to high but it can be balanced out. They're a little bulky as seen...

Worked great for the 1st 4 months

 

I really loved these headphones when I first got them. The sound is good and they are very comfortable, even after wearing them for 8 hours at work. Into the 4th month of use the headphones started turning themselves off every 5-10 minutes. I can turn...
