Sentey thorx $20 from sentey-ebay. These are great budget headphones!
Please read before considering purchase.
These headphones have a few problems. Small cracks on 1 side on edges in the middle, slight cigarette smell (I got them that way, I do not smoke), but mainly the right speaker cuts out in passive mode. Turning on the amp and noise cancelling almost always brings the right speaker back. I have no idea why it works this way and don't want to spend the time attempting to fix them.
So, I sell these cheaply and they are sold...
Here are mine with Denon d600 pads and this cable. http://www.ebay.com/itm/281525654696?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
The cable sounds same as stock and has a screw on 1/4 inch adapter
Pay shipping of $12
red beats demo model- requires a power source. I got these thinking I would convert them to non-powered use. I took one side apart, they are pretty complicated, and put it aside. Great for somebody who wants to finish what i started..
DO NOT ASK FOR THESE IF YOU DO NOT HAVE THE ABILITY TO WORK ON THEM PLEASE!
preference will be given to past customers/traders :)
