When I received the beats I immediately went to charge them first, the light came on and thought I was good to go. I bought this specifically to replace my old Barracuda backup drive so it is fit for purpose. Revision of initial review a couple of hours later after my right foot still hurt from shoe. It has a low noise floor which is ideal for my sensitive IEMs but it can also shift up a gear when it comes to my HD650s or over ear planars. They are stiff and uncomfortable, very narrow (and I have a somewhat narrow foot). The contours of the mouse fit nicely in my hand, but Id say its a little underweight --I find I inadvertantly lift it off the mousepad too frequently. HOMEKOKO thought of the little details during manufacturing that make the build easy and seamless. This skin adds a new look to your beats case and provides for a slightly better grip. This kickstand does exactly what its supposed to, it doesnt rattle, and it stays in place whether its down or up. this picture shows I went from step 1 to 2 and 3.
