I could see all sorts of things falling in to them. Cons:The game/voice adapter, I wish they would have made it a little harder to adjust it. Stylish shoes but it squeezed my left big toe and entire foot swollen for two days. I didnt get a lot of ambient room noise, just what was directly in front of the mic (and a little of the computer fans from behind me). Cant beat the lightness that Crocs are known for! I mean, isnt it much better than when you try the new technologies at the spa where if you get no result you are told "Sorry miss, it works for all our customers but for you". 0 ports are very useful to have since it takes up two USB ports itself. They pair easily via bluetooth, and stay in place very well. 5 to 5. The rhinestone band across the slippers BROKE.
