Nice sound, but did not fit my childs ear well. The K70 is Corsair?s middle of the lineup offering, above the $100 Strafe series but below the $190 K95 series. Would love another pair! these are very good. Having my heart set on them for comfort I went to the actual crocs store on vacation to get a bigger size and tried an 8. Used X-Treme Tape TPE-X36ZLB Silicone Rubber Self Fusing Tape, 1" x 36, Triangular, Black (amazon), works very well. Fit is great on the foot bed, and the heel cup holds my foot in place very well. they love them and sound has been great. Metal bars, metal shelves, easy to assemble by hand. I wear a size 10, so I purchased a size 10.
