Personal Freedom At Last

Overall these are above average headphones. The sound quality is good. Though they are very comfortable, they were not designed for excessive movement. They are great for sitting back and relaxing. If you are headed off to do chores around the house that require a lot of movement or plan to hit the home gym, you might think twice as these headphones have a tendency to slide off your head.

The auto tuning button and volume dial both on the headphones themselves is a plus. These headphones are even smart enough to turn themselves off when you take them off your head to save battery power. They have ample battery power (up to 20 hours on a single charge). I have tested them for 12 hours straight and they kept on going.

They only quarrels that I have with these headphones are the charging cradle, and the occasional interference. The charging contacts on the charging cradle and the ones headphones themselves don’t match up most of the time when placed on the cradle. They are easily knocked off the cradle, and if bumped just slightly the contacts don't align. When charging, the headphones have to be placed just so as to make contact with the charging cradle contacts.

I have these headphones hooked up to a computer, which has various other devices that transmit on the RF band (wireless keyboard, mouse, and remote) and there is no interference from these other devices. There is, however, occasional popping and hissing if you move around a lot. The only significant interference I have encountered is interference from 900 MHz telephones. Living in a multi-level apartment complex, I occasionally pickup conversations from people talking on the telephone. Which can be construed as good thing if you are James Bond. This is, however, easily remedied by pressing the auto tune button.
