I'm sure its the cable thats causing the problem. It only cuts out when I move the area around the plug and the problem goes away when I use the other provided cable. I would just switch to the second cable if it wasn't for the apple remote, plus the fact that a $600 pair of headphones died within 2 months...
its got the warranty amigo!
Just tell PFE about your problem, they should replace it no problem.
Interesting, and yes it could be the cable, by how u explain it it does seem to be a loose connection somewhere.
I assumed that it might be the driver, as I had the exact same problem with my W2's
Was cutting out, then one day, it stopped, but then the bass on one ear was much less lol
