I originally tried a Motorola HS820 which a number of people on the web have said works great. Mine had great sound quality but the sound on the other end was quite poor. Then I have tried this head set and it is a vast improvement. Clearly it is bigger than the Motorola but is quite light. After a few minutes you do not even know it is there. Others have complained about the small buttons, but it just takes a few minutes and you can master them. They work great. Pairs quickly with my Blackberry. Highly recommend trying.
