I was concerned I would have difficulty hearing everyone but 90% of the time I can leave these on the lowest volume . Happy with purchase for home gym. The ZEROs win hands down in comfort; its like soft, leather-wrapped pillows around your ears, and theyre large, but my ears got very hot very fast (and I was wearing them in a ~55-60 degree house). It was off by default on my watch. Toughest and most comfortable slide/flip flops Ive ever had! Directions with the product on- line helped. And theyre not refundable! I have the non-wireless changing airpods so I can?t say if it works with wireless charging, but the material seems to be one that would work nicely for it. Yes, these are flip flops. Not the loudest either and noise cancellation isnt that great but still pretty good for only around $20.
