However, once I started using it, I had overheating problems with both the pad and the phone (both got really hot), and I swore off wireless charging for fear of a fire hazard. I planned to use them for gardening but theyre so nice that I wear them out & about. Could also be used as a tripod for cameras. My husband has narrow feet - which I have found are very difficult to find shoes/slippers to fit. If you focus to outside or arent focused to music; you still may be able to pick out whats going on, but in general it does its job. Don?t imagine they would hold out for hiking rough ground. I put mine in the cutouts and could barely hear anything. At 20 Hz and at 20kHz there was no sign of saturation or added distortion. I don?t have any arch problems or foot problems so these are a keeper for me. They run somewhat large I probably could have gotten away with a size 9 or 9.
