Stop a Bluetooth Headset From Switching to Handsfree Mode

Windows keeps two devices for one headset. Disabling the Hands-Free profile stops music turning into a phone call, at the cost of the headset mic.

TL;DR

Disable the **Hands-Free AG Audio** playback device and the **Handsfree Telephony** service, then set the **Stereo** device as default. The headset stays in high-quality audio mode instead of dropping to call quality.

Before you start

Requirements

  • Windows 10 or Windows 11
  • A Bluetooth headset that is already paired
  • Admin rights to open the classic device properties
Step by step

Instructions

01

Find the two entries

Open **Settings > Bluetooth & devices > Devices**. The headset appears twice: once as headphones (stereo) and once as headset (Hands-Free AG Audio).

02

Set the stereo entry as default

Open **System > Sound** and choose the stereo entry as the output device. If you use the headset mic, do the same for the input.

03

Disable the handsfree playback device

In the sound settings open **More sound settings**, switch to the **Playback** tab, right-click **Headset Earphone (Hands-Free AG Audio)** and disable it.

⚠ warningAfter this, applications can no longer use the headset microphone - the profile carries both.
04

Disable the service as well

Open **Control Panel > Devices and Printers**, right-click the headset, open **Properties > Services** and untick **Handsfree Telephony**, then apply.

⚠ warningWithout this step Windows re-enumerates the profile at the next reconnect and the problem returns.
05

Reconnect and test

Unpair and pair once more, play music and open an app that grabs the microphone, such as a voice chat client. The audio should stay in stereo quality.

06

Use a separate microphone if you need one

A USB desk mic or the laptop's own array is the honest fix when the headset mic is gone. Trying to keep HFP and high-quality audio at the same time is what caused the switch.

tipA cheap USB-C lavalier beats the headset mic in quality and keeps the headphone profile clean.
Troubleshooting

Common issues

The handsfree device comes back after reconnecting

Both step 3 and step 4 are needed. If only one is applied, Windows recreates the profile.

No sound at all after disabling

The wrong entry was disabled. Re-enable the stereo device in the sound settings and check the default output.

The microphone stops working in calls

Expected - HFP is what carries the mic. Use a separate microphone or re-enable Handsfree Telephony.

FAQ

Frequently asked

Why does Windows do this?

HFP is a narrowband call profile. When an app opens the mic, Windows switches profiles and the audio quality drops.

Is there a codec setting for it?

No. Windows picks the profile by use, not by codec. AAC or LDAC support is separate.

How to undo this

Re-enable the **Hands-Free AG Audio** device in the sound settings and tick **Handsfree Telephony** again in the headset's properties. The call profile returns.
