FireS Audio Headphone Bridge

I wasn't a fan of how the [FireS Audio FireRock FR-H001](http://www.fires-audio.eu/index.php?item=fr-h001&action=article&group_id=8&aid=28&lang=en) headphone stand's thin metal would crease the padding on my cans.

This fits snugly on top of the two hangers as a bridge.
