I got these headphones about 4 or 5 years ago way before anyone even know what bluetooth stereo headphones were. They have been with me ever since. I take them everywhere and they have yet to give me problems. The bluetooth on these things is rock solid. I've had them paired to my phone and my laptop at the same time. Listening to music (and controlling it with the buttons on the ear pieces) then when call came in, it paused my laptop music, switched over to the call, talked for a bit hung up with the button and my music automatically resumed. They're truly perfect. I called them indestructible because I throw them in my backpack with my laptop and books all the time. They have yet to be bent or ruined in anyway. Mine have scratches all over from the way I treat them and after 5 years of continuous use the VERY comfortable padding on the ear pieces has started to wear away.The ONLY con I can think of is if you wear these headphones for over 4 or 5 consecutive hours you can feel them pinching in the area above your ears (where the band holds on to your head). However, this only happens after extended periods of time.I've been looking for another pair of bluetooth stereo headphones since mine are old and getting worn but I have yet to find any headphones that look and function as well as these.
