Solutions

Solution 1: Disable Bluetooth Power Management

1Open Device Manager → Bluetooth
2Right-click your Bluetooth adapter → Properties → Power Management
3Uncheck "Allow the computer to turn off this device to save power"
4Also check: Universal Serial Bus controllers → USB Root Hubs → same setting
5Restart the computer
6This prevents Windows from putting the Bluetooth radio to sleep

Solution 2: Reduce WiFi Interference

1If possible, connect your PC to Ethernet instead of WiFi — this eliminates 2.4GHz interference
2If using WiFi: switch to a 5GHz WiFi network (Bluetooth only uses 2.4GHz)
3Move the Bluetooth device closer to the computer
4If using a USB Bluetooth adapter: plug it into a USB 2.0 port (not 3.0)
5Use a USB extension cable to move the adapter away from the PC case and other USB 3.0 devices

Solution 3: Update Bluetooth Drivers

1Open Device Manager → Bluetooth
2Right-click your Bluetooth adapter → Update driver → Search automatically
3If that doesn't help: visit your PC/adapter manufacturer's website for the latest driver
4For Intel Bluetooth: use the Intel Driver & Support Assistant
5For Realtek Bluetooth: check your laptop manufacturer's support page
6After updating, remove and re-pair your Bluetooth audio device

Solution 4: Fix Audio Profile Switching

1Open Settings → System → Sound → your Bluetooth device
2Windows uses two Bluetooth profiles: A2DP (music, high quality) and HFP (calls, low quality)
3If quality drops during calls: go to Sound settings → Input
4Change the microphone to the built-in mic instead of the Bluetooth headset mic
5This keeps the headphones in A2DP mode even during calls
6In Communication apps: set the input device to built-in mic, output to Bluetooth headphones
