Just wanted to add/update on 4/28/2008 that this head set is still working great. Battery is long life still. Tons of stand bye time and plenty of talk time. Mine has not shown signs of breaking at the earpiece. I have been using it much more than when reviewed below and moved my rating up to above normal based on my use of it and reviews of more current blue tooth headsets ....

You can see all the info about this (Logitech? Mobile Traveller™ Headset) bluetooth headset at the Logitech website. What they say I am finding to be true. It sure is super lightweight.

Logitech? Mobile Traveller™ Headset is how I found it and the Model # on it is F-0399A.

The above link should get you there. I am not sure if this is allowed on Epinions? O well I couldn't get the link to post....

This is the only bluetooth headset I have ever had and so far seems like it may be the last. I mean that in a good way. It has so far been great. I have had it for 7 months I think and use it once, maybe twice a week for a hour of talk time. The battery seems to last a long long time between charges. I have never had it run out because I get scared it will die so I charge it finally. It is simple to use. Being that this is the only one I ever had I am not sure if others have better voice recognition when saying a phone number to be dialed or saying a contact name. This one seems to work with little repeating. My only trouble with it is, and this could be a big one for some people, that the incoming ring is not as loud as it should or could be. When talking on it I find myself turning down a loud persons voice yet when a call comes in I wish it could be a louder ring. I am going to ask Logitech about this when I finish writing this review perhaps...I found with music playing (maybe a bit to loud) in the car it is harder to hear the ring. With talk radio or quieter music it is OK. Also as far as I know the ring is not changeable by user...

I say expensive because I think I payed $80 US and see it here for much less than that. Maybe....
