The fit is good and the controls are amongst the best I've seen on any Bluetooth stereo headset. The sound quality is also good. But I had uneven results with connectivity. Even with my phone in my left pocket, I would lose signal fairly often, and have the song speed up, slow down, and skip. Simply moving it to my right pocket reduced, but did not eliminate, this concern. The problem happened with several different phones of different models, none of which had that problem with any of several other Bluetooth headsets, so I can only blame the headset.Buy Jabra BT620s Bluetooth Headphone!
