An excellent price / quality ratio! For that price, it's hard to have better. It holds well on the head, although the atria shake ears. The sound is of good quality, so does much for the microphone that lends itself to conversations via Skype, TeamSpeak or other communications software. As regards more particularly the sound, there is better, but it is already mounted in other ranges. In short: good product, excellent quality / price. As for lifetime, I do not know; this is just two weeks that I have.
