Troubleshooting Q.1 How to fix/change the call option due to accidental tapping on the left earphone? Go to your Bluetooth settings and turn off the phone control option. So it only has access to media. Go to your Bluetooth settings and turn off the phone control option. However, you will have to sacrifice the complete tap control. Q. What if only one earphone is working and the other one is not connecting? The best way to check if both earphones don’t have any hardware fault is that when both earphones are connected to the charging box they will have the Red LED light. If there’s only one light blinking this means that only one earphone is connected. Here are some solutions to connect the other one as well: Solution no.1: Put them back in the case. Take them out at the same time and wait for them to be paired. Wait for at least 20 to 30 seconds. Solution no.2: Try pressing the earphone which is not working for 3-5 sec. If nothing happens, try holding the sensor for about 30 secs. Solution no.3: It may be that one of your earphones which is not working might be low on battery. If you have already tried to charge it up and didn’t succeed. Try moving them around the box while the box light is blue, when they catch connection with the box, they will light up red. Use a paper towel or a tissue, do some folds and attach it inside the box top lid. Place the earphones and close the lid. Just try moving them around the box while the box light is running blue when they catch connection with the box, they will light up red. If one side isn’t charging, this will push the earphone of that side to attach with the charging terminal and charge. If you succeeded with solution no.3, it looks like we have the charging box defect here. If none of the solutions worked, your earpiece is faulty, go for replacing it.
