Why won’t my headphones show up in my Bluetooth device list?
The first step is to ensure your headphones are actually in pairing mode. Most Bluetooth headphones have a dedicated button or a specific sequence of button presses that activates pairing. Consult your headphones’ user manual to find the correct procedure. If they’re not in pairing mode, your computer or phone won’t be able to detect them. Also, check that Bluetooth is enabled on both your headphones and the device you’re trying to connect to.
Sometimes, the issue stems from having previously paired the headphones with another device. They may be automatically trying to connect to that device instead. To resolve this, try disconnecting them from other devices you’ve used them with before, or even forgetting the device from their Bluetooth settings. Then, attempt to pair them with the new device again after placing them in pairing mode.
My headphones paired but I can’t hear any audio. What’s happening?
Even after successful pairing, the output device on your computer or phone might not be correctly set to your headphones. Go into your device’s sound settings and make sure your Bluetooth headphones are selected as the primary audio output. On Windows, this is often in the “Sound” Control Panel. On macOS, check the “Sound” preferences in System Preferences.
Another possibility is that the volume levels on your headphones or the source device are too low, or muted entirely. Double-check the volume control on both to make sure they are turned up and not muted. Some apps also have independent volume settings, so ensure the app you’re using is not muted or set to a very low volume.
My headphones used to work fine, but now they’re not connecting at all. What changed?
A recent software update on your phone or computer can sometimes cause Bluetooth connectivity issues. Operating system updates can occasionally introduce bugs or change Bluetooth drivers in a way that affects compatibility.

You might also try restarting both the headphones and the device to clear any temporary connectivity glitches.
How do I know if my Bluetooth headphones are the problem or my phone/computer?
The easiest way to isolate the problem is to test your headphones with a different device. If your headphones connect and work properly with another phone, tablet, or computer, then the issue is likely with the original device you were trying to connect to. This narrows the troubleshooting to that specific device’s Bluetooth settings or drivers.
If the headphones still don’t connect or work properly with any other device, then the problem is almost certainly with the headphones themselves. This could indicate a hardware malfunction, a software glitch in the headphones’ firmware, or a low battery. In this case, try charging the headphones fully, and if the problem persists, consider contacting the manufacturer for support.
My headphones connect, but the connection keeps dropping. How can I fix this?
Bluetooth connections can be susceptible to interference from physical obstructions. Walls, furniture, and even your own body can weaken the Bluetooth signal. Try reducing the distance between your headphones and the device you’re connected to, and ensure there are as few obstructions as possible.
Also, Bluetooth connections can be unstable if there are too many devices competing for bandwidth on the same Bluetooth frequency band. Try turning off Bluetooth on other devices in the vicinity that you’re not currently using. This can free up bandwidth and improve the stability of your headphones’ connection.
My headphones are detected, but pairing fails with an error message. What should I do?
Check your device’s Bluetooth settings for previously paired devices, especially if you’ve paired the headphones before. Sometimes, corrupted Bluetooth profiles can interfere with new pairings. Delete the old entry for your headphones and try pairing them again from scratch after putting them in pairing mode.
If the pairing still fails, try resetting your headphones to their factory default settings. The method for doing this varies depending on the model, so consult your headphones’ user manual. Resetting them will clear any stored pairings or configurations that might be causing the problem, and allow you to start with a fresh pairing process.
My headphones are connected, but the sound quality is poor or distorted. How can I improve it?
Ensure that the Bluetooth codec being used for the connection is appropriate for your headphones and device. Some headphones support higher-quality codecs like aptX or AAC, but your device needs to support them as well. Check your device’s Bluetooth settings to see if you can manually select a different codec.
Another potential cause of poor sound quality is interference. Other Bluetooth devices or Wi-Fi routers operating on the same frequency can cause distortion. Try moving away from potential sources of interference and ensuring that your headphones and the connected device are as close as possible to each other.
