The Jieli BR21 chip is a highly integrated, low-cost Bluetooth microcontroller developed by Zhuhai Jieli Technology. It is widely used in budget-friendly wireless consumer electronics, including Bluetooth receivers, car audio adapters, wireless headsets, and USB dongles.

This is the most common Bluetooth issue on Windows. When you use the microphone on a standard Bluetooth connection, Windows automatically switches from the high-quality "Stereo" profile to the low-quality "Hands-Free" profile.
