Query: do not waste your time with these headphones

I have used blue tooth headphones for many years now, I have personally worn out three motorola HT820 head phones, I am working on a pair of S3's. The blueant is very comfortable to ware, but if you use them to listen to go to sleep and cover the front or side, the signal will fail and fail only one foot from a blue tooth transmitter. A major problem is when the unit is charging, and you unplug it, the power is on and if you forget to turn it off, it will burn down the batteries are dead for when you need it. I am still looking for a comfortable pair of stereo bluetooth headphones, but the blueants are not them.
