Good one!

I bought two of these for two pairs of headphones. However, this holder is long enough to carry comfortably two pairs of pretty large headphones. I have Audio Technica ATH-M50x and Beyerdynamic DT-800 Pro.

It's adjustable for up to 45mm thick desks, and quality is on K&M level.

Use this holder, it's much better than leaving your pricey hadphones on a desk.
