My Bose QC 45s have the most annoying low battery warning I've ever experienced. Beginning at 10% battery, every 5 minutes all input media is paused so a computer generated voice can inform me "BATTERY LOW, PLEASE CHARGE NOW." 10% battery can last for up to an hour, but woe betide you for trying to utilize the time.
It is an atrocious UX. It cannot be disabled via the paired mobile app. Do not buy these headphones!
