It seems like that we are seeing a lot from Sennheiser these days with their stuff at CES 2011, their recent CXC 700 earphones, not to mention the PX 360 and PX 360 BT Headphones.

Right now, Sennheiser has a deal going down on the HD 515. It is “fitted with the company’s E.A.R. technology along with Duofol diaphragms to reduce unwanted resonances to an absolute minimum”.

These are not wireless headphones, but it looks like it gives out some pretty good sound. There is an unboxing video at my Source link if you would like to see them close up.

The original price of these guys was about $129.95, but now Amazon has them for 58 percent off at $54.92.
