Up for sale is my Sony MDR-Z7. On the verge of 'Excellent/Like new' condition but these have seen a lot of use, and the pads do show it a bit (though there is no issue, just some visible wear). I'm moving so I'm trying to downsize. If I can't sell this week this will need to go on hold. Awesome comfort and build, really cool 70mm drivers, and the soundstage really feels large from that and the cups. This is a 'warm' sounding headphone with a lot of bass. I'm mostly looking for a sale but would be willing to trade (cash on either side) for:

OTL tube amp with low noise/no hiss on sensitive headphones
