I think its best to refrain urself from gettin razer headsets.
their gaming mice is awesome, been using my DA nearly 3 years.
still works great.

i own a piranha and a charcharis.
both had similar malfunction after a usage of 6 months ++
1.speakers start crackin up
2.then lost of hearing in in left speaker. had to mess around with either the audio jack behind the pc or volumes clip to get that left speaker to work again.
3. zzz. the left speaker cracks up again n lost of hearing. usually happens after a sudden rise of sound.
maybe from gun fire, a chopper flying by or hearing techno musics.
4. the volume clip fails utterly.
its volume up/down label on the clip wore up after frequent use.
and so does the mute mic button labes.

overall. awesome for a lifespan of less than 5 months.
im lookin into logitech g930 wireless.
im traumatized my wires n volume clips now.
