I was a bit hesitant on purchasing this phone due to the negative reviews on here, but I decided to try it and Im glad I did. Overall i would recommend this controller over the previous model and idk compared to other pro/3rd party controllers though. 2 inches. The mouse is solid in terms of build quality in these latest models as far as I can tell, no wiggle in buttons, new updated cable and it goes out forward in the box rather than the old wrap around the back you see in early reviews (prevents disconnect issues). This is the worse headphones I ever bought. I love how it came with the threading needles as well. Nothing more enjoyable than ordering a product only to be put through doing the basic debugging the company should of done during development. They also dont have the annoying touch sensitive "technology". I bought this to try to tame the shoe mess in my mud room. i would suggest u spend couple of thousand less and get AKG p120 if u r vlogging.
