i also have an N900 and a BH-214 headset, and work as a tech in a datacentre. I also use the combo when cycling and walking the dog.

i find that all round the comination is a winning one. I found that the range is outstanding, and the audio quality spot on. I can cheerfully leave the N900 on the desk and walk around the dept, and the music keeps playing.

I have a full pair of bluetooth headphones, and the bh-214 is much better. it's lighter, more compact, and i find being able to clip it to an itme of clothing is great.
