Query: Comfortable, Good Sound, but Useless!

This unit would NOT stay paired to my phone, but kept coming un-paired when on standby. This completely defeats the purpose of having a BT headset since you have to reactivate the connection every time you want to make a call or answer the phone.It was so comfortable I didn't know it was there and had great sound quality. If not for the "Fatal Flaw" it would get 5 stars.
