Since it was 3 pair for $9. It is not safe for iphone 12 pro max, it slides and the surface is hard scratches the phone, it only works with the apple magsafe cover. Bought this so that I could simply attach it to my existing 4 bike Thule 954 Ridgeline hitch unit. You CANNOT fit the AirPods Max in the smart case in this case. I purchased my rack used for $30. Too small and as others have said, make a terrible ‘farting’ sound when you walk. & I ordered a small. Equally clear speaking quality is the response I hear from others with whom I am gaming. Soft lining so will not scratch headphones. I would have been glad to post a positive review voluntarily, but being forced to do so in order to receive the "free gift" just felt wrong.
