Looking to upgrade to the Pionner 800c, but these work very well, so I find it hard to spend the money unless I sell these first. They are perfect for me in my NYC apt where space is a luxury and the neighbors will complain if the decibel levels are too high. Well you can listen as LOUD as you want with these and they are cordless. (Listened to the Britany Spears In Miami concert last night in dolby digital, my wife's favorite)
This the Sony MDR DS5000 virtual surround dolby digital version. I got them about 4 years ago and paid $399. In fact the headphones were just replaced because the transmitters finally gave out. They are new $109 to replace, got them last week. I have the original box and it comes with a fiber optic cable.
This is perfect for a student or husband that likes to watch dvds and digital tv late at night. In fact I wear these doing the day becauce I perfer the sound. Thanks for the interest.
