I'm extremely happy with these so far. Sound quality is good, wireless range using its USB bluetooth dongle is excellent, and noise cancellation seems good (though I don't use them in a particularly noisy environment). Charge seems to last quite a while and they recharge fairly quickly via USB cable in a power bar.The big feature for me is that they sit flat "on ear" rather than cupping around the ear as most headphones these days do; and for me this is kind of essential for comfort. I don't know if I've got larger-than-normal ears, or they protrude more than is common, but I find the vast majority of ear-cupping headphones extremely uncomfortable to wear for extended periods of time. These ones sit flat on the ear which I assume means they aren't able to cancel out surrounding noise quite as well but for me they're infinitely more comfortable to wear.
