I have lots of colleagues who use various BT headsets. I find the outgoing voice quality apalling on most of them. I need a headset to use both in my office and in my car. I would prefer a wireless solution (I would love a in-ear style earbud like my Sennheiser CX300), but outgoing voice quality is the most important factor. I presently use an Sony Ericsson K660i and (quite seldom) voip from my iPod touch, the problem with using a wired headset with that handset is that the clunky connector tends to fall out. Our cell phone choices is very limited by our head office, so a change of phone isn't in the cards at the moment.

I have checked out the Jabra JX 10 Series II and Plantronics Voyager 510 and 520 (only online so far).

Budget: under $150
