After a long-time search to replace my old pair of (broken) noise cancelling headphones, I finally settled on the Logitech Ultimate Ears brand/line. I was holding out for Bluetooth+active NC, but ultimately decided they weren't worth the price and (short) battery life (although the UE9000's sounded better than any other BT headset); in addition, BT performance is usually compromised compared to "wired" performance. The Logitech's also double as a (stereo) headset, with a mic included on the headphone cord. While they are middle-of-the-road on noise cancelling (which is good enough for me), they are OUTSTANDING as a straight headphone. I looked at: Parrot, Sennheiser, Beats, and Sony (Sennheiser 500/550 would have been my second choice).
