Bluetooth earbuds sound bad on calls because turning on the microphone pushes them into a low-quality, mono phone mode. Your earbuds aren’t broken. The usual fixes are to use your laptop’s mic instead, turn off the Hands-Free setting in Windows, use a headset with its own USB dongle, or try Bluetooth LE Audio if both devices support it.
You’ve probably noticed the pattern: music sounds fine, then you join a Zoom call and everything turns thin and tinny. A Microsoft forum poster described the same thing with Discord and Google Meet, where the background audio either disappeared or sounded very poor. The cause is built into how classic Bluetooth works, and every fix has a trade-off.
Why Bluetooth Earbuds Sound Bad on Calls
Bluetooth uses two modes for audio:
| Mode | What it’s for | What you get |
|---|---|---|
| A2DP | Music, video, podcasts | Good stereo sound, no microphone |
| HFP (Hands-Free Profile) | Phone and video calls | Microphone works, but sound is mono at a lower bitrate |
Screenshot this table, because it explains every fix below.
BGR’s explainer says playback uses A2DP, then the connection switches to the hands-free mode when you join a call. That switch changes the audio from stereo to mono and drops spatial effects. A blogger writing about Teams on Windows 11 puts it this way: the current Bluetooth spec doesn’t let a headset receive high-quality audio while it’s also sending microphone audio. Answers on Microsoft’s forum say the same, and add that apps generally can’t override the switch.
These are explanations from writers and community answerers, not official Microsoft statements. We haven’t measured the quality drop ourselves.
Pick the Fix That Fits How You Use Your Earbuds
| What matters most to you | Best fix | The trade-off |
|---|---|---|
| Good sound, and you don’t mind your laptop’s mic | Fix 1: use the laptop mic | People hear you through the laptop, not the earbuds |
| Windows keeps flipping to the bad mode | Fix 2: turn off Hands-Free Telephony | The earbud mic stops working |
| You need the earbud mic and good sound | Fix 3 or 4: LE Audio or a dongle headset | Needs supported hardware |
Fix 1: Use Your Laptop’s Mic and Keep the Earbuds for Listening
In Zoom, Teams, Discord, or Meet, set the speaker to your earbuds and the microphone to your laptop or webcam mic. Because the earbuds’ mic isn’t in use, they can stay in the better playback mode. BGR lists this as a workaround that works on any device.
One catch from the Teams writer: choosing separate devices in the app doesn’t always work, because Teams can still force the hands-free mode. If that happens, add Fix 2.
A note on conflicting advice. Wyze’s support page says poor call quality on a computer is a known bug with Zoom and many chat apps, and tells Wyze Buds owners to select the earbuds as the microphone instead of the computer’s built-in one. That’s the opposite of Fix 1, and it applies to those earbuds. Different earbuds behave differently, so try both settings on a test call.
Fix 2: Turn Off Hands-Free Telephony in Windows
This stops Windows from switching your earbuds into the call mode. These steps come from a 2023 Windows 11 guide, and menus may differ on your version:
- Open Settings, then Bluetooth & devices, then Devices.
- Scroll down and select More devices and printer settings.
- Right-click your earbuds and choose Properties.
- On the Services tab, untick Hands-free Telephony, then click OK.
- In your call app, choose the earbuds for sound and your laptop for the microphone.
For AirPods on Windows, BGR describes a different route: in Sound Settings, open More sound settings, select “AirPods Stereo,” and click Set Default. If that isn’t enough, open the Recording tab, right-click “AirPods Hands-Free AG Audio,” and disable it.
The trade-off is real. A Microsoft forum poster who did this said the audio became good, but the earbud microphone stopped working. To get the mic back, tick the box again. BGR also warns that a deeper fix, turning off the Bluetooth Audio Gateway Service in Windows, affects all audio devices, so we wouldn’t start there.
Fix 3: Try Bluetooth LE Audio
BGR says newer Bluetooth LE Audio can avoid the old trade-off. On Windows 11 it needs version 22H2 or later, and both your PC and your earbuds must support it. We couldn’t confirm that any particular budget earbuds do, so check the spec sheet before you count on it. The idea is similar to the low-latency codec rule in our guide to connecting Bluetooth earbuds to a TV without Bluetooth: both ends have to support the feature.
Fix 4: Use a Dongle Headset or a Separate Mic
If you want good stereo sound and a working microphone at once, the Microsoft thread’s advice was to use a headset that comes with its own 2.4 GHz USB dongle, which doesn’t depend on standard Bluetooth. Another option, from the same thread, is a separate wireless microphone. That’s more gear to buy, but it avoids the switch entirely.
What About Phones?
The BGR article says switching the microphone is harder on a smartphone, and gives no phone steps. We couldn’t find verified, step-by-step instructions for phones, so we’re not guessing. If calls on your phone sound thin, the same cause applies, and a wired or dongle headset is the clean workaround.
Does Sound Quality Ever Mean the Earbuds Are Faulty?
Usually not. If music sounds bad too, or one side sounds wrong, that’s a different problem. The audio lag version of this problem is covered in our guide to Bluetooth earbuds out of sync with video. If you’re still setting up, our laptop pairing guide walks through a clean connection first.

Frequently Asked Questions
Why do my Bluetooth earbuds sound bad on calls? When the microphone turns on, Bluetooth switches from stereo music mode to a hands-free phone mode that is mono and lower quality. It’s a limit of classic Bluetooth, not a defect in your earbuds.
How do I make Bluetooth earbuds sound better on Zoom or Teams? Set the earbuds as the speaker and your laptop or webcam mic as the microphone. If the app still forces the call mode, turn off Hands-free Telephony in your Windows Bluetooth device properties.
What happens if I turn off Hands-free Telephony? Calls sound better, but the earbuds’ microphone stops working, so you’ll need your laptop mic. You can turn it back on by ticking the box again.
Can I have good sound and a working earbud mic? Possibly, with Bluetooth LE Audio if both your PC and earbuds support it, or with a headset that has its own USB dongle. Check the spec sheet before you buy.
Why does music sound fine but calls sound terrible? Music uses a high-quality stereo mode. Calls use a mono hands-free mode. The switch happens when an app starts using the microphone.
