I have paired the head set with both my computer and phone. Both work great with the head set. The phone that I am using is a motorola v3 and it works great. It takes a couple seconds to connect but you have enough time to connect the two and answer the call before it goes to voice mail. If you are going to use a head set with a phone alot I would sugest using one that supports voice commands like "digit dial" to keep you from having to store voice dails for everyone you want to call.Next I have also paired it to my computer to a cheep bluetooth adaptor that I bought just to sync a palm. I have not used the mic yet but I am sure that it will work great as it does with the phone.On both phone and computer. Sound is great I have not had any problem hearing on either one.This one seems to be getting mixed reviews so it may not work on your set up but you never know till you try. This headset is small and light weight so I would atleast have to try it out.
