Review on Sweatproof and Washable Wicked Cushions Large WC SweatZ Protective Headphone Ear Covers, Compatible with Beats Studio 3 & 2 (Excludes Beats Solo), Bose QC35 & 35II, Bose 700, and More (Large Size, Brown) by Marlo Schlachter

The seller said these would fit my Sony WH1000MX4 headphones. They do not fit. When I put the cases on the headphones, after about 5 minutes they start slipping off the headphones. (At this point the headphones were on the table. I tried putting them on the headphones several times but to no avail. Then I tried putting them on just before I put the headphones on. It hurt a lot from that Level of compression from undersized cases I contacted the seller They asked for proof that they are not properly seated I don't think a photo of cases partially removed would be proof Yes they are oval shaped like my Sony headphones. But these cases are about 2-2.5mm smaller than my real headphones. While this might seem like a small difference, the difference in size is actually significant. And size is very important when you put cases over these headphones. No try to stretch them will work. I found them really well made and with quality material. I have 1000MX3 installed so can't compare them.
