These sandals surprised me in the best way and I?m so happy with them! However it just broke down randomly after I tried it one day. Ok, so theyre not leather etc etc but they are value for money (got all mine at reduced sale price) and have had plenty of compliments with every style. Packaging was well done and made me feel confident in my purchase. Not a dealbreaker for me. 151649] Under-voltage detected! Orderd the s-mIm a size 7. The memory foam compresses well, and expands slowly so you can easily insert them into your ear and wait for them to expand (that does take a few seconds, which is also a minor irritant, but for the results Ill take it. Kind of curious how long it lasts. 3mm cable as well and another adapter.
