Modern PCs typically have single 3.5mm port for headphones and mic. Y-connector adapter connects headset and mic to single jack. Adapters cost less than $10 and come with audio-in/out jacks. 3.5mm-to-USB adapter allows connection via USB port
Bluetooth audio cuts in and out randomly or disconnects even with full charge. WiFi interference with Bluetooth devices can cause stuttering
Bluetooth can be turned on in Windows Settings under Devices or Bluetooth & devices. Windows 10 users press Windows+I, Windows 11 uses Windows+I+I. Check Device Manager for Bluetooth adapter presence to verify support
Windows 10 users report Bluetooth issues after upgrade. Bluetooth may disappear from Device Manager or Control Panel. Issues include missing Bluetooth icon and connection problems
Ensure Bluetooth is enabled on PC and headphones are discoverable. Check headphones are charged and within range
