Reluctantly selling these as they are my frankenbabies . Changed original grill for a more airier one and lined it with a less restrictive lining (leggings) to ensure no dust gets inside the driver. Comes with Beyer replacement headband. Also 90% Jerg-modded ( still have to sew the 2 layers together). I had originally installed a 4 pin XLR connector on the end of the wire but recently put back a 1/4 Double helix plug.
