The build quality- Im giving it an A+, this thing is solid and feels good to touch and to be honest ive heard alot of reviewers said its heavy i dont feel it. Deserve 5 star. Chargers with multiple coils are a must-have for people who, like me, own multiple wireless charging enabled devices and find cables messy and annoying at times. Please order a size up! Theyre really soft and the kids couldnt be happier. But they are still a great price and when you think of the good they are doing by donating a second pair of shoes its totally worth it. I have an old pair of EMU slippers that have incredible bounce in the sole (they are at least 3 years old and still very supportive/comfortable. Also a very small fit ! Until the memory foam starts to do its job and compress over time, i might compress them overnight with something lightweight on top of the headphones. But it is a little uncomfortable on the ear, if I wear it for to long.
