I ordinarily wear a Womens 10 so that is what I ordered. Pretty easy to install as long as you know what wires to connect. Un buen juego que recrea la experiencia en el puente. Really comfy right out of the box. The quality of the sound is amazing, they use Realtek audio chips and you can tell from the clear and crisp sounds and deep bass when listening to music. Sadly, I can only get it in BT mode. I ordered the black pair in a size 9. I ordered one more for my Grandson, they worked for one week and would not charge. The clicks on both mouse1 and mouse2 are so clicky you probably wont go with any other mouse that isnt mechanical. The cord is too long, though.
