The sound quality is very good, but some people may prefer to do more tweaking in the EQ app of their choice. and I wasnt disappointed! Powered them up and they were absolutely perfect! I recommend you stretch them from the inside with your fingers over the rim of headphones. Id order a size up if you can. I purchased the leopard print and will be getting another pair in black and/or red. I can walk 80 from my phone and still get calls and no back ground noise. We came home and opened the outside package which was fine. Cannot recommend a better all around play shoe for kids! I also got them on sale at around 56$.
