I just received this headset from a online company. My first impression was that the unit is bigger than what I saw on the internet. However after a few days of using I got used to it, since it goes behind your ear and you don't see almost anything besides small black microphone, sticking out for about inch and a half.The unit is :- very light- very comfortable ( you can wear it whole day, without noticing it )- long battery life- hassle free set-up ( as with all Bluetooth headsets )- vol. button on the headset and voice dialing button- if you have a longer hair, no one will see that you have a headset - so it will be like you are talking to yourself.- The ear gels make sound clearWhat I didn't like was the working distance of the Bluetooth. Jabra claims 30ft, but it is nowhere near. If there is a wall between you and the phone the conversation will crackle.Also I wish you could change the sound alert on the headset - it is a little annoying after a while. .. I also turned off the vibrating alert - even though sometime I may use it ( in a loud places ), it is just another ( in my opinion ) selling point for Jabra.Do you know where the Bluetooth name came from?It is after king Harold Bluetooth ( Danish king Harald Bltand ), which was known for unification of tribes from Denmark, Norway and Sweden.
