I think the people who complain about being unable to charge the device did not read the manual. Do they realize that it is not supposed to stay red but to flash intermittently while charging? I had no problem whatsoever charging this headset.The best part of this headset for me is that it comes with the small ear piece. My ears and ear canals are very small and everything falls out. I wear glasses so I don't want to wear a loop over my ear.It sounds great to me and those I am calling.I reccommend this headset.
