A:Answer Based on the provided information, the Soundcore Anker Life Q20 Hybrid Active Noise Cancelling Headphones do not need Bluetooth in order to provide basic functionality such as wearing them for sound isolation. You can simply wear the headphones without music or any connection to protect your hearing from certain noises.
Additionally, the headphones can be used in AUX-in mode if desired (by connecting via a 3.5mm cable to a device), though this won't activate noise cancellation, and Bluetooth is not necessary for this mode. If your primary goal is ear protection, you can use the headphones as passive noise isolators without any active features.
