I wonder why so many folks say the motorola S9 headset is for indoor use only..I've had mine for over 2 years now and they work great .. they could be alittle louder but that's me getting older,, for those that have the orginal S9 and wish to upgrade to the HD check this out..

I use the BH-604 on my N900.
The only downside about this headset is that it's much bigger than all other headsets in this thread
(IMO this is not a downside but i guess some of you would like it smaller)

Soundquality is simply amazing.
Crystal clear sound and a warm beep bass!
and it's realy pleasurable to have this on your head because it's so soft.

The battery lasts over a week when i use it every day 2-4 houres

here in belgium it costs €90. Wich imo is waaaaaaaay to cheap for this headset
