Sound quality is reasonable and the fit is good as I wear them when running. These boots were purchased for my 14 year old, as the style looked like what she wanted. Only (minor) cons are the dedicated cell phone pocket is too small for an iPhone 6 with a case. Id give them five stars for that alone. I dont expect a lot of comfort from shoes in general, but these were surprisingly VERY COMFORTABLE. I received these shoes on July 24. They didn?t stay on my feet. Doesnt fall out while workouts or running. Pros -ComfyDecent soundEasy to useCons -The removable mic is a nice touch but can get lostLimited and basic software, couldnt find EQ settingsPS4 connection is glitchy I exclusively wear Vionic shoes -- sneakers, flip flops, you name it.
