Have you tried to connect the headset to your N900 with the cable? When using cable I cannot switch the songs or anything... Other devices work with it, though.
Great review and it definitely answered some of my bluetooth headset questions, thanks. I use the Shure 530 ear buds so I really like the isolation I get from them (plus the sound is hard to beat) but a wireless headset would be cool too. Btw, whereabouts in Sydney are you from?
