Dropouts, one silent earbud and the pairing that forgets itself
Bluetooth audio drops out for a short list of reasons, and the pattern of the dropouts usually points straight at one of them. Cutting out in a busy station but not at home suggests interference. Cutting out whenever the phone goes into a back pocket suggests your body is in the way. One earbud falling silent while the other plays suggests the link between the earbuds, not the phone. Work out the pattern first; the fix follows from it.
Read the pattern of the dropouts
| What happens | Likely cause | First thing to try |
|---|---|---|
| Stutters in crowded places, fine at home | Radio interference on the 2.4 GHz band | Keep the phone in your hand or a front pocket |
| Cuts out with the phone in a back pocket | Your body blocking the signal | Move the phone to the other side or a front pocket |
| Drops when the laptop is nearby | Multipoint: another device grabbing the connection | Disconnect the earbuds from the laptop |
| Stutters even at home with high quality audio | A high bitrate codec with too little headroom | Set the companion app to prefer a stable connection |
| Disconnects after the screen goes off | Battery optimisation stopping the companion app | Exempt the app from battery optimisation |
| Only one earbud plays | The link between the earbuds, or one is flat | Put both in the case, then reset the earbuds |
| Will not reconnect at all | A stale pairing record | Forget the device on the phone and pair again |

Fixes, from the quickest to the most thorough
- Put both earbuds back in the case for ten seconds This resyncs the pair and clears most one sided dropouts.
- Turn off the connection on other devices Earbuds that remember a laptop and a tablet will hand themselves to whichever one makes a sound. Disconnect them there, or turn off multipoint in the companion app.
- Lower the codec quality High bitrate modes need a strong, clean signal. Choose a stable connection setting in the companion app, or a lower quality in Developer options under the Bluetooth audio codec settings.
- Exempt the companion app from battery optimisation In the app's settings under Battery, choose Unrestricted. Aggressive battery savers on some brands close it in the background and take features with it.
- Forget and pair again Remove the earbuds from the phone's Bluetooth list, reset them using the button sequence in their manual, then pair them as new.
- Update the earbud firmware Firmware arrives only through the companion app and often improves connection stability. Keep the app installed for that reason alone.
- Reset network settings as a last resort Most phones offer a reset for WiFi, mobile and Bluetooth under System and Reset options. It forgets every network and paired device, so it is the last step, not the first.
Companion apps and small tools
Galaxy Wearable, the hub for Galaxy Buds settings and firmware, with a plugin installed for each earbud model.
Sony Sound Connect, formerly Headphones Connect. Its connection quality setting chooses between best sound and a stable connection, which fixes many LDAC dropouts.
JBL Headphones, for firmware updates, the equaliser and the touch and connection settings on JBL earbuds.
The soundcore app from Anker, with firmware updates, noise cancelling modes and connection options for its earbuds.
Jabra Sound+, for firmware and sound personalisation on Jabra earbuds and headsets.
The Bose app for its earbuds and headphones: firmware, connected devices and noise cancelling settings.
Nothing X, for Nothing and CMF earbuds, with firmware, the equaliser and a low latency mode.
Sennheiser Smart Control Plus, the current app for recent Sennheiser earbuds and headphones.
Settings and firmware for Pixel Buds on phones other than Pixels, where the controls are otherwise built into the system.
A system wide equaliser with correction presets for thousands of headphone models. Not a connection fix, but worth having once the connection holds.
Battery levels and a connection pop up for AirPods on Android, where Apple offers no companion app for them.
Read the pattern, then work through the fixes in order: the case, other devices, the codec, the battery saver, a fresh pairing, firmware. Most dropouts are gone by the third step.
Frequently asked questions
Why does only one earbud cut out?
In many designs the phone talks mainly to one earbud, which passes audio to the other, so the second depends on a short link across your head. A reset in the case, with both charged, fixes most cases. Persistent trouble in one earbud is often a hardware fault covered by warranty.
Does a higher quality codec sound better?
On good headphones in a quiet room, sometimes slightly. In the street, a stable connection at a lower bitrate sounds better than a high bitrate one that stutters.
Can a phone case cause dropouts?
Rarely on its own. Metal cases and magnetic mounts can weaken the signal a little, and that matters when the connection is already marginal.
