I found the top end to be overly harsh to the point that music was fatiguing to listen to. Pretty disappointing since the shoes are so very expensive. Quite apart from the fact that the heating effect of microwaves is not how they damage you, that head is based on a six foot two inch man, so it has no bearing on the majority of the population who arent above-average-size, such as the many women and, increasingly, children who are regular users of microwave devices. Nov 2020 update: I still LOVE these shoes! the velcro strap makes these easy to put on so there is nothing to complain about with these. Also I wanted to add the IKEA Eneby 20 and 30 to the bang-for-buck line up; lose portability, but provide much bigger sound! Bluetooth is just a bonus He was pleased. But the issue I had was that literally the earbuds did not last me a month. 5 foot deep.
