Before the SBH52 gets here, this is how I make my calls. Share your method!
I use the Bose bluetooth Series 2 headset.
I have had this baby for 6 months now, and it's been great. Initially, my ear got sore for a little bit, but then got used to it, and the tip got soft. The sound quality is very good for calls. It doesn't actually cancel noise, but it increases the volume when noise levels around you increase.
If you want to listen to music, this is not the best device for it since it is for 1 ear listening, but it does Ok. The base is nice for 1 ear.
It also does last number dial with a double tap of the answer button. Battery life? I have to charge it every night.
