Fits my Bose QC20 headphones like a glove and keeps them far more protected than the official Bose case. We ordered the longer version of this. What can you say really. For the stud, I ignored their instructions and used a 3/16 drill bit (they suggest 9mm which to me seemed WAY too big), and I made a mark on the bit at 7/8" so I only drilled into the wall/stud that deep. The souls are just a centimeter too short. So soft and fuzzy inside and solid construction on the outside. This is my first Bose purchase and I?m happy. Eher nichts für schmale Füße. There are many options online; I even bought another pair elsewhere but they felt lower quality so I returned. Plugs straight into my USB-C plug.
