Connection is excellent, comfort is brilliant, sound quality is great and battery life is borderline infinite. The covers for the analog sticks are secure and feel good on the thumbs. This show fits like a glove. I bought this on a whim because all the reviews I could find didnt mention fitment. I ordered a size 5 and had to return it was so tight and when your feet swell throughout the day it would have been unbearable! Very disappointed and unable to get an exchange or return, because it happened 4 days past the 30 day return policy! Why does it stop charging? I guess what I should ask is, why does the light flash from red to blue constantly? When that happens it stops charging my phone. Would totally recommend as a gift. The rear rubber flap could have had better placement, a little higher up so the USB cables arent so low incase someone accidentally rolls the speaker backwards with something plugged in, but thats just being nit picky. Otherwise, these are great.
