Edit: Whoops, forgot to link pictures! Updated.Though these are very hard to come by nowadays, I'd like to fund other projects that I have in mind. These will be missed!Production began in 1987 and ended around 1992. The biggest draw (at least for me) is that its driver is made of amorphous titanium rather than PET/mylar (used in most headphones today) in the V6. The left and right indicators are gold colored rather than blue for left and red for right on the V6, 7506, CD900ST, etc. The words on the headband are golden rather than silver on the V6, 7506, CD900ST, etc. Basically, it's a very special model from the golden age of SonyThey perform very well - I like them a lot more than the V6. The V7's are much more refined in the treble and has a punchier bass. Its bass has a very unique texture to it that makes them very fun to listen to - I have yet to hear this from any other headphone. Last thing to mention is that the CD900ST is NOT the same as the V7 - I've seen some mention this on various forums; different diaphragm material: amorphous titanium vs PET/mylar.Excellent condition considering its age. Very minor nicks along the edges of the earcups. One small imperfection on top of the headband. Underneath the headband has some lines but isn't flaking. Those are the only cosmetic notes that I can see - all imperfections are pictured in the link. Most headbands I've seen on other V7's have heavy flaking.Earpads are authentic and like new - I bought them off of Amazon about a month ago with little use. Does not come with its 1/4" adapter. Comes with just the headphones.Excellent condition as well. No nicks on the earcups. Some imperfections on top of the headband - all imperfections pictured in the link. This pair also has lines under the headband but isn't flaking.This pair comes with Yaxi microfiber earpads. Extremely comfortable to while keeping the sound mostly unchanged. I got these for 42 USD +7 USD shipping recently so they're like new. Will come with its 1/4" adapter and just the headphones.-------------------------From a smoke-less and pet-less home.Ships from MN.Feel free to PM me any questions about the headphones!
