I believe that I passed by Sennheiser’s booth at CES 2011, but I don’t know why I didn’t report on anything from it.
Here are some of the new headphones, the PX 360 and the PX 360 BT. The BT stands for Bluetooth connectivity support, and the are collapsible and circumaural.
It features a natural sound with strong bass, Neodymium magnets, and includes SRS WOW HD SurroundSound technology.
You should be able to get the PX360 for $199.95 and the PX 360 BT for $399.95, and they come with its own carrying case.
