Like the other hanger by Adv. that attaches to the desk, it's built well, very solid and study with a heave base to support whatever headphones you need supporting.
It's useful for headphones with a metal band which is separate from a leather band (like the HE1000v2), or headphones with a certain notch shape (like the HD6XX), but I would not use this with headphones that have a padded headband (like the Focal Elex).
The height works quite well and the weight distribution is well balanced. The stand feels very stable. I appreciate the little reclaimed desk real estate!
