I was replacing a Plantronics 220 that had given me 3 years of faithful service with this Motorola. Out of the box, the charger connector was too loose to keep a tight connection so had to be placed "just so". After full charge it took several tries to pair the set to my phone. Volume was good, but none of the several options using the multi button could be accessed. No voice dial could be used; no redial function and if you pressed the function button a "hair" too long the headset muted itself. It took deleting it from the phone, re-pairing the set. Seems this "New" motorola bluetooth is either defective or a return that was placed back into service and sold as new.I am ordering a Plantronics and will not take the time to get an RMA. Not worth my time and trouble. Sad for the dealer that sold this junk and Motorola for poor product.btw, my phone is a Motorola Razr V3, a perfect match for the HS820 headset; so I was told. NOT! Do not buy this headset...
