Someone had written among features that buds would reduce noise, but are dissatisfied with that part. Talk is heard straight through. I have also experienced BT hassle that others have written about. May have the phone lying 10 meters away behind a wall, but as soon as I have it in the pants pocket it is roulette whether the sound chops or not. But is satisfied with the purchase for other aspects and has chosen to keep them.
+ Completely cordless and avoids the 'thread scratching' noise that can occur with other in-ear lures. In general, all problems that arise with threaded handsets are forgotten with these
+ when I'm in the gym don't hack them. As long as the phone is still at a location in the room.
+ is possible to have earmuffs over without degraded effect, just have to have the phone at chest height on the front of the body so that it will not hack, I have chest pockets so it works for me.
+ goes a week before I load them in the cable AND just the thing with them being charged in the case is worth your own star.
