The sound on these was too poor to use during phone calls; people consistently told me they couldnt hear me or that I sounded very far away. He has 1/2" behind his foot left in space. Its not Amazons fault that the fit is not quite as expected but to avoid a future return I think I had better visit an actual store this time. The Velcro doesnt sit perfectly where it needs to, but it does the job, and i cant complain about much else since my son will only be in these about a couple of months before he grows out of them. Its not the best but neither it is the worst. These have absolutely no support at all. 5 but they could have fit my feet better if they were a half-size bigger. I think a lot of others will do the same. Other headphones start to hurt, or fall off of my ear, or both. The range on them is very impressive and I was still able to hear clear sounds with no cutting out at ranges of 30-40 feet from my phone!
