17mm is what I needed. Presentation and feel out of the box whilst not premium is certainly businesslike, they are light but feel strong in the hand and have an unusual but flexible arrangement for the inner headphone band and the pads are also soft to the touch. it has a good coverage for our conference room. While it cant work with Oculus Link because it doesnt pass data though itself, this isnt important to me as I dont own a PC powerful enough to run that sort of content. I can get them wet like Havianas . I attached photos of myself in each. My only issue is they sent me the wrong color, but the speaker is great. If you want more support I?d look at the other styles they have instead. I put up the dowel and then hung the clothes. I do wish they were just a little bit longer so I had the choice to store shows in a box in the case as well.
