XM3 has a usb-c connector with fast charging, so it's better than XM2. Going to 100% takes a while though (maybe about 1 hour) but charging it for about 10 min

XM3 has a usb-c connector with fast charging, so it's better than XM2. Going to 100% takes a while though (maybe about 1 hour) but charging it for about 10 min is enough to get you going for the whole day. I charge mine about once a week. As for the noise cancelling, I haven't noticed much of a difference with XM2, but I'm not an audiophile anyway, so I'm not sure.
