These bad boys on the there hand, fit and they are comfortable and sounds superb. This is my favorite mouse I have ever owned, and for people that like a low profile, the color mode can be switched off if you want to focus at night. Cute, but a bit small. Turning on and off was a breeze with the touch feature. They fail to grip the temples and several times they almost came off! When you need an arch support, buying shoes is a bit difficult especially on line. I will use it temporarily, but will likely look for another option that offers protection but allows easy access to the key release. I?m sure I?ll settle on my favourite but right now I haven?t found one that is actively uncomfortable. In addition, there was no indication of which was the forward side and which was the back side of a rack. Honestly happy I got this.
