"Not good with iPhone 4S. Volume is always Max"1.5 starson by avg_guy
Pros: Size, Fit, battery life
Case will extend battery life
Once connected in a call its awesome sounds as good as speaking directly on the iPhone 4S
Cons: Case - You cant charge the receiver with out it - non standard connector on the bluetooth device itself.
Volume control - non existent. Every time the unit is turned on the volume is set to Maximum
Interface to Siri - Volume is not controllable.
Summary: I want this unit to work so bad. It fits my ear. I've tried Blue Ant and Jawbone. Neither work for me as they do not fit in my ear.
