I previously had a Jabra BT350 for my Blackberry and had a lot of problems with it...primarily with the multi-function button which would consistently call the last person I called when I was trying to pair the device with my phone. I was very interested in the Motorola HS850 due to the flip-boom activation. I was hesitant to spend the money after ready some negative reviews, but I finally purchased it and I love it. The sound quality is good and although it takes some getting use to to get properly on your ear..once its there it is a good solid fit.The best part about this unit is the flip-boom. It allows for quick and easy pairing with no danger of placing calls you don't want to. Also you don't have to commit to how you are going to answer the phone...you can leave the bluetooth with boom closed and when the phone rings either answer normally or flip the bluetooth and answer that way. Very user friendly well worth the price.
