When using Bluetooth headphones, it is important to not wear them for too long. If worn for more than an hour, it can have a significant impact on hearing. When wearing headphones for a period of time, it is necessary to remove them to relax and rest the ears, and alleviate auditory fatigue. If it is possible to use external speakers without affecting others, try to use external speakers or speakers as much as possible.
