Here’s a lightly used Capra audio 3d printed headstrap mod for the Hd600 series headbands. Works with the 580, 600 ,650 and the drop x series and 660 series.

The mod adds more comfort than the stock nuggets but I like having my HDs stock and I have previously accidentally snapped my old hd600 headband trying to put these on so I highly recommend taking your time installing this mod.
