Short Summary:
The sound is quite OK, I used to hear it mainly to sleep and audiobook. I could hear no weakness and no strength, sound, etc. was just fine. Durability was also good from my experience (usually Philips with me about 1 year), disintegration began but at a little earlier before he broke down after 14 months.
(A headphone has completely "dissolved")
Well I found together holding something closer to the Y-cable a small Plastk limiter of the cable if necessary.
Negatives, there were also: The cable (the plastic) feel "sticky" as normal cable, which is not bad but even feels good, however, the cable twist by more often / easier which leads to clutter.
And the fit for the ears was not so great, here really had to on left / right attention which led to the replacement in the dark more often because others were Philips Universal and thus more comfortable.
Since I got the headphones for a very reasonable price (about 12 euros), I am satisfied, I would have paid more I would annoy me now rather. So, as recommended offer, at normal prices to the 20, - Euro I find it too expensive.
