The only redeeming quality is that these are pretty good for a $30 headset. Be aware that if you stack these the top shelf of each one will be a lot shorter in height because they were apparently not designed to be stacked. Cosas que aprendí y que debes considerar antes de hacer un upgrade de ram. My daughter has a narrow foot and these stay on easy. Actually these ones were slightly cheaper sold by EYES ON TOES than ROCK DOVE FOOTWEAR. Die Höhen werden recht Klar wiedergegeben, zumindest so lange man den Kopfhörer nicht bis zum Anschlag aufdreht. I would not buy this product again. I should have gotten these years ago! Of course I?ve worn other styles of shoes also. Either Nike has seriously downgraded in the materials they use to make these shoes, or these are a cheaply made knockoff being advertised as Nike.
