These headphones were namely by far the toughest I've ever had. Under the harsh conditions that my headphones were constantly exposed (crumple in the pocket, in bed rumwälzen it, over it accidentally rolling office chair and chew on it unconscious) have these headphones persevered almost a year. By comparison, other cheap headphones and even a 20 headphones from Philips have collapsed after only a few months under the conditions. Not so these headphones.
The sound is quite good for my needs. Has a good bass and are replaceable in-ear rubbers supplied if you have smaller ears.
Small drawback is that the headphones do not work on any normal jack (since there is actually a smartphone headset). Then the sound is tinny, but what can be remedied by persistent pressure on the button on the headset. Is just a bit annoying.
By now I'm back (by mistake) rolled through the headphones so that the cable is bare. The interested headphones very little. Have the place fixed something taped, yet runs the already a few months through! Highly recommended!
