I ordered the S size in the two pack(black and brown). Software is average or on par with anyone else?s. Peal off the tape on the back, and stick it up. There are 4 baskets-2 large/2 small, 4 adhesives, 8 screws with nice covers and anchors. Beautiful, comfy, easy to put on and off by herself, true to size. The Sennheiser Smart Control app is easy to use and works well. Ive had them two months and the outer sole is about done and as a result, the foam underneath the sole is wearing around the edges. This actually makes the transparency mode slightly worse so if that matters to you don?t use these. Very happy with this purchase :) Can?t wait to take them for a spin on the dance floor.
