After going through more headsets that I care to recall, I have finally found one that not only works reliably, but also is comfortable, inexpensive, and offers superior performance.Pairing is a little tricky - be sure to save the little instruction card, as the combination of buttons is not intuitive, IMO.The battery life is excellent in both standby and talk mode - I am constantly amazed at how long this thing can sit in my car's center console unused and still be ready to go for a long conversation once paired. By the way, pairing with the iPhone is flawless - it seamlessly pairs and unpairs, switching easily even between paired headsets (or in my case a Jabra speakerphone and this headset).The only reason I have not given in 5 stars is the *#$&^ proprietary charging connector. WHY, oh WHY do companies insist on reinventing the wheel constantly??? PLEASE JUST LET ME USE ONE OF THE BAZILLION mini-USB ADAPTERS I ALREADY HAVE!!!Value: 5 starsPerformance: 5 starsReliability: 5 starsComfort/fit: 4 starsDesign: 2 stars (only because of the charging adapter!)
