I had a chance to listen to these at the CES show and i was impressed with the sound.

First off, these headphones use KLEER technology for their wireless. I'm a big fan of this and have been since Sennheiser used it in their RS 180. IMO it is the best for wireless because it doesn't really have any interference or noise or static. Plus, it has really good range. I put the headphones on and can walk around the house, go to the bathroom, make some food in the kitchen... all while listening to the TV and without taking the headphone off.

Back to the Syncs. I like the design of the cans and the simple to use controls on the sides. i found them very easy to use. Plus, the buttons stick out enough (and are big enough) that you know what button you are pushing without having to take the headphones off.
