How to Use Earbuds with Mic on PC? | Make Them Your Default Mic

Getting your earbuds’ mic working on a Windows PC comes down to one step most people skip: telling Windows which microphone to use. The fix for a silent mic is rarely the earbuds themselves — it’s the input selection hiding in Sound settings.

Pair or Plug In Your Earbuds First

Wired earbuds with a mic usually work the moment you plug them into the headphone jack or a USB port. Bluetooth earbuds need to be paired before Windows will list them as an audio option.

To pair Bluetooth earbuds on Windows:

1. Open Settings > Bluetooth & devices.
2. Turn Bluetooth on, then select Add device.
3. Choose Bluetooth and pick your earbuds from the list when they appear.

Put your earbuds in pairing mode first — usually by holding the button on the case until the LED flashes — so they show up in that list.

Select the Earbud Mic in Windows Sound Settings

Pairing alone doesn’t switch your input device. Windows keeps using your laptop’s built-in mic until you change it.

Microsoft’s documented path is Start > Settings > System > Sound. Under Input, choose your earbuds’ microphone from the list, then select Properties and run Start test to confirm Windows is picking up your voice.

A common mistake is pairing the earbuds and assuming the mic switches automatically. It doesn’t — the input device must be selected manually. Also check that the Output section lists the same earbuds, or you’ll hear nothing while the mic works.

Set the Mic Inside Your Calling App

Apps like Microsoft Teams, Zoom, and Discord have their own audio settings that override Windows defaults. For Teams, open Settings and more > Settings > Devices, then choose the earbuds in both the Speaker and Microphone menus.

Two other settings block mics silently. Check Windows privacy settings under Settings > Privacy & security > Microphone and confirm the app has permission. And verify the app itself isn’t muted or set to the wrong input in its own audio menu.

Why Mic Use Can Change Audio Quality

Bluetooth earbuds commonly expose two profiles in Windows: a stereo “Music” profile and a “Hands-Free” or “Headset” profile. The mic only works through the hands-free profile, and that profile often drops audio to lower quality or mono sound. That’s why music sounds fine but calls sound thin — the system switched profiles to enable the mic.

Newer Windows 11 versions reduce this tradeoff. A 2024 Microsoft update introduced a new Bluetooth audio architecture, and stereo audio while the mic is active requires Windows 11 24H2 or newer on build 26100.4484 or later, with qualifying LE Audio hardware. If your PC supports it, you’ll see Use LE Audio when available under Settings > Bluetooth & devices > Devices. If that setting is absent, your hardware doesn’t support LE Audio.

Windows 10 has no LE Audio support, so the stereo-vs-mic tradeoff stays in full effect there.

For video calls where voice clarity matters more than music quality, the hands-free profile works fine. If you notice choppy or robotic call audio, it’s usually the Bluetooth connection struggling — moving closer to the PC or removing obstacles between them often helps. Wired earbuds avoid this entire issue since they don’t switch profiles.
