This is my pair of Fostex Mahogany THX-00 - one of the early models from massdrop without the detachable cables. The headband on these headphones is fairly flimsy and mine broke a few months ago - i put some tape on it to stop it from completely disintegrating but eventually gave up on them. The pads are also fairly old and dirty so will need replacing - i have some brainwavs pads but not sure if they would fit.
I'm hoping to sell this to someone who can use the cups and drivers because they still work fine and these are a great sounding headphone. I'm open to trades or a straight sale - make an offer!
