You open the case, put your headphones on, and… nothing. No chime, no music. Bluetooth headphones not connecting is one of the most common gadget complaints, and it usually comes down to pairing memory, power or a driver problem. In this guide I’ll show you how to fix it on phones and Windows laptops, then cover the other accessories that tend to misbehave the same way.
If your headphones connect but sound cuts out on your PC, that can be a Windows audio issue. My guide on fixing Windows 11 problems like high CPU and missing audio covers that side.

Why Bluetooth Headphones Won’t Connect
- The headphones are still connected to another device, like your tablet or old laptop.
- The battery is too low to complete pairing.
- The saved pairing record is corrupted.
- Bluetooth is off, or Airplane mode is on.
- Outdated Bluetooth drivers on Windows.
- Interference from Wi-Fi routers, microwaves or USB 3.0 ports.
10 Fixes for Bluetooth Headphones Not Connecting
1. Charge the Headphones Fully
Many headphones refuse to pair below 10–15% battery. Charge for at least 20 minutes before trying again.

2. Disconnect From Other Devices
Turn off Bluetooth on nearby phones, tablets and laptops that previously paired with your headphones. Many models connect automatically to the last device they used.
3. Toggle Bluetooth Off and On
Turn Bluetooth off on your phone or PC, wait 10 seconds, and turn it back on. This clears minor glitches.
4. Forget the Device and Pair Again
On your phone, open Bluetooth settings, tap the headphones and choose Forget. On Windows 11, go to Settings > Bluetooth & devices, click the three dots and choose Remove device. Then put the headphones into pairing mode and connect fresh.
5. Reset the Headphones
Most headphones have a factory reset, usually by holding the power or pairing button for 10–15 seconds. Check the manual for your exact model.
6. Move Closer and Reduce Interference
Bluetooth works best within about 10 meters with no walls in between. Move away from your Wi-Fi router and avoid plugging USB 3.0 devices right next to a Bluetooth dongle.
7. Update Drivers on Windows
Outdated or incompatible drivers are one of the most common reasons Bluetooth fails on PCs. Microsoft’s guide to fixing Bluetooth problems in Windows recommends running the Bluetooth troubleshooter and reinstalling the driver from Device Manager.
8. Update the Headphone Firmware
Brands like Sony, Bose, JBL and Samsung release firmware updates through their companion apps. These often fix pairing bugs.
9. Check Bluetooth Version Compatibility
Older phones and laptops may struggle with newer headphones. The Bluetooth SIG’s learning hub explains how versions and profiles work if you want to dig deeper.
10. Restart Everything
Restart your phone or laptop and power-cycle the headphones. It sounds basic, but it solves a surprising number of cases.
Wireless Earbuds: One Side Not Working
When wireless earbuds have one side not working, the problem is usually charging or sync between the two buds:
- Clean the charging contacts on the bud and inside the case with a dry cotton swab.
- Put both buds in the case, close it for 30 seconds, then open and try again.
- Check your phone’s audio balance setting under Accessibility; it may be shifted to one side.
- Forget the earbuds on your phone and reset them using the case button.
- Gently clean the mesh with a soft dry brush if the sound is low rather than gone.
How to Connect Wireless Earbuds to a Laptop
Here’s how to connect wireless earbuds to a laptop running Windows 11:
- Put the earbuds in pairing mode (usually by holding the case button until the light flashes).
- On your laptop, open Settings > Bluetooth & devices > Add device > Bluetooth.
- Select your earbuds from the list.
- Click the sound icon in the taskbar and choose the earbuds as your output device.
On a Mac, open System Settings > Bluetooth and click Connect next to the earbuds.
Bluetooth Speaker Not Charging
If your Bluetooth speaker is not charging:
- Try a different cable and wall adapter; laptop USB ports often provide too little power.
- Inspect the port for dust or corrosion, especially on “waterproof” speakers used near water.
- Let a cold speaker warm to room temperature; many won’t charge in the cold.
- If the speaker hasn’t been used for months, leave it plugged in for an hour; deeply drained batteries can take time to wake up.
Smartwatch Not Connecting to Phone
A smartwatch not connecting to your phone often comes down to app permissions:
- Make sure the companion app (Galaxy Wearable, Wear OS, Apple Watch, etc.) is updated.
- Allow the app to run in the background and turn off battery optimization for it.
- Keep Bluetooth and location on, as many watches require both.
- Unpair and re-pair the watch through the companion app, not just Bluetooth settings.
Wireless Mouse Not Working on Windows 11
When a wireless mouse is not working on Windows 11:
- Replace the batteries or recharge the mouse.
- Plug the USB receiver into a different port, ideally a front USB 2.0 port.
- For Bluetooth mice, remove and re-pair the device in Settings.
- In Device Manager, check for warnings under “Mice and other pointing devices.”
USB-C Hub Not Working With Laptop
If your USB-C hub is not working with your laptop, check whether your laptop’s port supports data, power delivery and video. Not every USB-C port does all three. Also:
- Plug the hub’s power adapter in if it has one.
- Update your laptop’s chipset and USB drivers.
- Avoid daisy-chaining too many power-hungry devices.
Portable Monitor Not Detected by Laptop
A portable monitor not detected by your laptop is usually a cable or port issue. Use the cable that came with the monitor, connect to a USB-C port with DisplayPort Alt Mode (often marked with a DP or Thunderbolt icon), and press Windows + P to choose “Extend.” My guide on fixing a slow Windows 11 laptop also covers the second-monitor detection steps in detail.
When It’s Time to Repair or Replace
If you’ve tried every fix above and your headphones still won’t pair with any device, the problem is likely hardware. Signs include no lights when charging, a case that won’t hold charge, or crackling audio even over a cable. Check your warranty first; many brands replace faulty earbuds within the first year. If the warranty has expired, compare the repair cost with a new pair, since budget models are often cheaper to replace than fix.
Final Thoughts
Most Bluetooth problems are fixed with three steps: charge, forget, and re-pair. If that doesn’t work, update drivers and firmware. For wired accessories like hubs and monitors, the answer is almost always in the port type and cable. If your Wi-Fi is also acting up, check out my guide on Wi-Fi connected but no internet, since router interference can affect Bluetooth too.
FAQs
Can Bluetooth headphones connect to two devices at once?
Only if they support multipoint. Check your model’s specs or companion app.
Why do my headphones connect but play no sound?
The output device may still be set to speakers. Select the headphones in your phone or PC’s sound settings.
Does Bluetooth drain my phone’s battery?
Modern Bluetooth Low Energy uses very little power, so leaving it on has a small impact.
