Before buying a bluetooth headset for my Pearl I researched all of BBF and the Net for the best one.
The model most praised was the Nokia BH-900.
I have been using mine for about three months now and I have to say it is the best.
-- It easily connects with the Pearl.
-- Range is excellent. I can use it about 30 feet or so with walls between the headset and the phone.
-- Battery life on the internal rechargeable battery is good.
-- People say that when I am talking through it my voice is clear.
-- The volume on the headset can be adjusted so it is very loud in noisy environments.
-- It is very light. I have left it hanging on my ear and forgot that I was wearing it, sometimes as long as five hours.
-- Best part, these retailed for $130. Now they can be bought on eBay for as low as $30, plus shipping.
After three month's testing, I 100% recommend this BlueTooth headset.
