JayBird X2-M user manual

There could be several reasons why only one of your Jaybird earbuds is working. Here are a few possibilities:
1. Connection issue: Make sure both earbuds are properly and securely connected to each other. Sometimes, one earbud may lose connection or become loose, causing it to cease functioning.
2. Battery level: Check the battery levels of both earbuds. If one earbud's battery is drained or significantly lower than the other, it may not produce any sound.
3. Bluetooth pairing: Ensure that both earbuds are properly paired with your device. Sometimes, if one earbud is not properly connected or paired, it may result in only one earbud producing sound.
4. Audio balance setting: Verify that the audio balance settings on your device are not favoring one side. Adjusting the audio balance to a neutral position might resolve the issue.
5. Hardware or software malfunction: It is possible that there may be a defect or issue with the earbud itself. Try resetting the earbuds or reaching out to Jaybird customer support for further assistance.
Remember to read the user manual or refer to the manufacturer's website for specific troubleshooting steps, as different models may have varying solutions to this problem.

The problem could be due to several reasons such as below:
1. Low Battery: Your left Jaybird might not be connecting because the battery is low or dead. Check if charging resolves the issue.
2. Pairing Issues: It could also be a pairing issue. Try un-pairing your headphones from your device and then pair them again.
3. Interference: Sometimes, a third-party device on the same frequency band (Bluetooth) could cause interference. Try to disconnect other Bluetooth devices and reconnect your headphones.
4. Faulty Piece: Lastly, it is possible that your left jaybird is faulty. If none of the above troubleshotting steps work, you should consider reaching out to the seller or manufacturer for a product exchange or repair.
