I'm a fan of AKG's N60 NC, which may be the best on-ear noise-canceling headphones available, so I was pretty stoked when AKG put out a Bluetooth version called the N60NC Wireless. They cost $300 (£250, AU$400), which isn't cheap, but they're very good wireless headphones that not only sound excellent but are compact and fold up nicely into a travel-friendly neoprene carrying case.
On-ear models that sit on top of one's ears aren't everybody's cup of tea, but the 7-ounce (198g) AKG N60NC Wireless are about as comfortable as you get for this type of headphone. What's also noteworthy is that they have effective noise canceling with only a very faint hiss.
This new wireless model has some design improvements to the earcups, with a little bit thicker padding and a headband that doesn't clamp down on your head as tightly, which leads to a more comfortable fit. Battery life is rated at up to 15 hours with both Bluetooth and noise canceling engaged (that's good but not great) and up 30 hours if you use the noise canceling only in wired mode.
My only design complaint was that I had a little trouble with the track forward/back button that's located on the right earcup (pressing it pauses or plays your music and answers or ends calls). It's kind of a rocker switch and when I went to advance a track it sometimes took a few tries to get the track to advance (I had no trouble getting tracks to skip back). Also, the power switch is a little too close to the track control and I sometimes accidentally turned the headphones off because I had my finger on the wrong rocker switch.
