I haven't tried yet, but do bluetooth headphones work for full audio / mic with the One X ?

Thinking of getting these, nice feature set!

Yes, they do. I use them with LG HBS700 (excellent headset btw) and they work very well.

I just checked those headphones out. They look pretty sweet, but $170 seems a bit steep. You might want to give these a try: Amazon.com: Kinivo BTH220 Bluetooth Stereo Headphone - Supports Wireless Music Streaming and Hands-Free calling: Cell Phones & Accessories. They're only $30, and they qualify for free shipping. Battery life and sound quality are great for the price. I've had them since July; I work out 1 hour, 3 times a week and have only charged them twice. I've used them maybe 5 or 6 times for calls to different people, with no issues on either end.
