Question:

Why does the left earphone of my wired-bluetooth headset malfunction when connected via cable?

I have a headset that supports both wireless and wired modes. However, when I plug in the cable, the left earphone stops working. This does not happen when I use the bluetooth mode. What could be the cause of this problem and how can I fix it?

Answer:

Wired-bluetooth headsets are convenient devices that allow you to enjoy your music or calls in both wireless and wired modes. However, some users may encounter a problem where one of the earphones stops working when the headset is connected via cable. This can be frustrating and confusing, especially if the earphone works fine in the bluetooth mode. What causes this issue and how can you solve it?

There are several possible reasons why your left earphone may malfunction when connected via cable. Some of the common ones are:

• Faulty cable: The cable that connects your headset to your device may be damaged or defective, causing a poor or no connection to the left earphone. This can happen due to wear and tear, bending, twisting, or exposure to moisture or heat. To check if this is the case, try using a different cable that is compatible with your headset and see if the problem persists. If the left earphone works with another cable, then you need to replace the original cable.
• Faulty jack: The jack that plugs into your device may also be faulty, preventing the left earphone from receiving the audio signal. This can happen due to dirt, dust, lint, or corrosion that accumulates in the jack over time. To check if this is the case, try plugging your headset into a different device and see if the problem persists. If the left earphone works with another device, then you need to clean or replace the jack on your original device.
• Faulty earphone: The left earphone itself may be faulty, due to a loose or broken wire, a blown speaker, or a defective circuit board. This can happen due to physical damage, overheating, or manufacturing defects. To check if this is the case, try using your headset in the bluetooth mode and see if the problem persists. If the left earphone does not work in either mode, then you need to repair or replace the earphone.

Depending on the cause of the problem, you may be able to fix it yourself or you may need to contact the manufacturer or a professional technician for assistance. Some of the possible solutions are:

• Replace the cable: If the cable is the culprit, you can simply buy a new cable that is compatible with your headset and use it instead of the old one. Make sure the cable is of good quality and fits securely into the headset and the device. Avoid using cables that are too long, too short, or too thin, as they may affect the sound quality or cause interference.
• Clean the jack: If the jack is the culprit, you can try cleaning it with a toothpick, a cotton swab, or a can of compressed air. Be careful not to damage the jack or push the dirt further inside. If the jack is corroded, you can try rubbing it with a pencil eraser or a cotton swab dipped in alcohol. If the jack is still not working, you may need to replace it or take your device to a repair shop.
• Repair or replace the earphone: If the earphone is the culprit, you may be able to fix it by soldering the loose or broken wire, replacing the blown speaker, or swapping the defective circuit board. However, this requires some technical skills and tools, and you may risk damaging the earphone further. If you are not confident or experienced in doing this, you may be better off buying a new earphone or sending your headset to the manufacturer or a repair shop for service.
