Let the hive mind of Engadget get that for you.
"For a long time I have been searching for a portable device where I can store all of my CDs in MP3 format and stream the songs wirelessly to my HiFi system. The portable device must I've tried FM transmitters, they all suck. I don't want a docking station. Any help? Thanks!" have a display so that I easily can scroll through the playlists (I don't want to use a TV or monitor). I suppose that there must also be a second device that is connected to the HiFi system that would receive the wireless streams from the portable device.
V6's have excellent sound reproduction and isolation, and have a comfortable bass level. You can't beat Grados for proper sound reproduction, but you don't want to wear them for a long time and the bass levels are a little lacking for casual listening.
V6s are used in radio, TV, and virtually every other type of audio production situation - while not the highest priced, many maintain that they are one of the most balanced and refined headphones ever produced for professional use
I've had my V6's for 7 years (I was in HS when I bought them - imagine the abuse!), and they are absolutely rock solid. I had to replace the ear pads (replaced with Beyerdynamic pads - don't get as warm or oily, but increase the distance of your ear from the driver)
Probably the wisest $60 investment I've ever made. Just buy them.
