I have the Beats x and honestly, you may as well just buy any pair of bluetooth headphones. The only benefit is the nice connect screen. After that you still have to go to bluetooth settings to press on it anyway. You can use the airplay option when playing something but half the time it doesn't show the headphones anyway. Maybe an iOS11 bug but it's annoying! I switch between iPad, iPhone and Macbook sometimes it doesn't connect and I have to hold the button to turn off, on to pair and connect and it picks it up.
Also, I can never get the things to fit in my ear properly.
I gave up and have been using a pair of Shure SE215 since saturday. Noise isolation is superb, quality is superb and no connection problems. Also, fit is superb! I actually traded in a pair of Beats EP. Sound is dreadful! I have a pair of B+O H2 now (amazing sound). The Beats EP sounded just dull and muffled to my ears! Also, cable is quite delicate. Headphones build is very good though.
