Hi, i'm after some advice. Really good noise cancelling when not playing music (as well as when playing music) is really important to my son. He's autistic but has to spend most days in quite busy, loud environments. He's had the XM5 headphones for years and they've been amazing but theyre starting to break due to extremely heavy use and he's trying to decide between the 1000X expensive new ones, or the XM6. He likes the comfort & sound quality of the 1000X but does anyone have any info on how the noise cancelling functionality compares to the XM6, especially when not playing music?
