Hmm, I have to say I tried this one for about 15 minutes in the bose store, and I found the sound quality was actually quite poor. I think the NC was too high and the user interface on the device (as well as the wear ability, it won't do I think LEFT ears it was not symetrical YET) was somewhat poor. not to mention it was some serious $$$. It has now been discounted for between 79-99$ in aftermarket.
