I bought the earphones about 8 months ago and used them maybe twice or thrice a week. While I cannot complain about the sound quality, everything else is a bit off. My cable got damaged on it's entry to the jack (I'm using the earphones with my smartphone, which sits in my jeans pocket) so I had to return in to Logitech (on the bright side, Logitech agreed to replace it no questions asked). Cable seems a bit heavy as I need to pull half of it out of my shirt so that the earplugs would have a stable fit - otherwise they keep getting pulled downside...
