I've had these for a little over a year and they have outlasted all the other ones, even some brand name ones. I don't know if anybody else has had the same experience with this type of in-ear neckband bluetooth headphones, but they don't last me very long. Maybe is because I use them constantly, even to sleep, but always within a few months of use one the earpieces become partially disconnected (poor soldering of the contacts I guess) and the sound on that side goes on and off, but mostly off. Not these. They're also very comfortable, very light but they stay in place better than heavier bulkier ones. The charge time is very quick and a full charge keeps well over 8 hours. The sound quality is very good, obviously not Sennheiser or Bose but an excellent value for the money, so I'm getting another pair.
