Very disappointed in these boots. The sound is good, but not better than beats. I appreciated the fit a lot more than I expected - these are light headphones, they don?t grip too tightly, and let my ears breathe easily, which is much appreciated. This product makes it sound like your underwater. I received a pair of slides ,one of my slide fit my foot,the other one was to small I shouldnt put it on. Nooooope. They may be OK in the next size up, but Im not willing to chance it. I?m 5?11? and normally a size 10/12 and the Large fits like a glove! Despues de usarlos 3 meses, siguen como nuevos. I can still wirelessly charge my case with the case on which is a giant plus.
