I had 4 pairs of these headphones, and at best, they have survived a year, really the best.
attaching the input shaft in the atrium is misplaced. Every time we introduced the plug into the ear canal, a little on the cable is pressed, and obviously what ends up happening is logical: the cable ends up dropping out (the solder is not resistant), it starts with a few false contacts and the ear becomes mute to end up not giving her, definitely. And despite the pseudo guarantees to life that had worked in France a while (changed on request at FNAC for example), we expect not a product of such a reputable brand as KOSS, having to be changed every year. 4, 3 have had the same problem, the 4th, a much more common problem is the cable that comes in the drive, at the outlet, which began to have the game to end there and not give in yet leaving only a single functional ear.
His side is alas my biggest regret. Being fond of this big sound and balanced bass, from this point of view it's just a marvel cheap and a hell to find a replacement worthy of his level of sound quality. Hence my eagerness to resume. I even tried the white version, to have exactly the same problem, with, in addition, a lower sound quality.
I finished with a Sennheiser CX500: much worse in terms of sound, too many middle, bass much lighter but strong in almost 3 years now walk, metro, rer, he has not moved and just beginning to show some signs of weakness (weakening of the sound level of an ear when the cable is in a certain angle).
Verdict: excellent headphones in sound (especially at this ridiculous price), but absolutely unacceptable quality finish (or so buy 3 or 4 at once).
