Having issues with the ANC in certain settings. When at work I use them around some things like vacuums or ultrasonic cleaners. They are terrible at cancelling this noise, and sort of high frequency white noise they make a weird buzzing noise trying to cancel it out, its awful and deafening. Hopefully a software update can fix the anc. Also sometimes when I put the earbuds in they make a weird screech noise trying to balance pressure or something.
