Quality: once is not imitation, hard to find negative points to an Apple product, however the atria may have sometimes tend to fall ears a little too fast; but it is better than too tight and painful ear. Impeccable quality, can not beat that price. Also rendering microphone is exceptional.
Delivery: being free in 1 business day so I took advantage of it, so obviously nothing to say either. :)
Compatibility: works fine on iOS. Android, the microphone works during calls, and the main button functions to pause, press 2 times to go back one title 3 times to advance.
