I purchased one pair of these wedges and loved them, then purchased three more. Bei den geschlossenen Schlappen von Birkenstock muss man auch nicht eine Größe kleiner bestellen. I bought the AURTEC "Replacement Earpads for Sony MDR-RF970R. Keeps the kids in one place while using the VR! The second and bottom shelves are flat. Sound quality very good and works well with cellular iPhone and desktop computer when using webcam virtual meetings. But, as I waffled about the price, my wife not-so-gently reminded me how demanding I am about my sound quality and how I use my earphones all day EVERY day and that you get what you pay for. UPDATE: March 2, 2017 This bed is horrible! Nothing and I mean nothing I have tried can measure up to the pure joy I have experienced since receiving these headphones. The tag inside slippers states that they are made of all man-made materials and are machine washable.
