i12 TWS Manual: How to charge i12 TWS?

I12 TWS Headphone charging

Put the headphones in the slot of the charging case, and then turn on the charging case. The LED indicator will flash red and turn off after a full charge.

Charging the battery box (charging case)

When charging the battery box with a USB cable, the LED indicator will light yellow and green. If the LED blinks 2 times it means your battery is 50% full, if it blinks 3 times it means it is 75% charged and if it blinks 4 times it means it is 100% full.

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.

    1. Hi Nicole!
      Is one of the earbuds not charging or is it the whole charging case? The case does show charging light and so does earbuds.

      If the charging case is not charging, try replacing the cable with another one. If this doesn’t solve the problem, the charging case might be faulty.

    1. Simply, put them in the slot of the charging case, and then turn on the charging case. The LED indicator of the earbuds will flash red and turn off after a full charge.

      If one isn’t charging it means that it is faulty. Are you able to listen to the right earbud which isn’t showing red LED light when you put it in the case? If the LED doesn’t lighten up, it means they are faulty.

      I had QCY T5 as well and one of them got faulty. Since I had another i checked changing the case and putting them in each other cases and it was the earbud. So, in most cases earbud is faulty and if the charging case is faulty none earbuds will charge.

    1. For most models, the charging case blinks LED light to indicate whether it’s charging or not.

      When charging the battery box with a USB cable, the LED indicator will light yellow and green. If the LED blinks 2 times it means your battery is 50% full, if it blinks 3 times it means it is 75% charged and if it blinks 4 times it means it is 100% full.

      If it is not blinking that it means that either the LED is faulty or the case not charging at all. If the earbuds don’t light up red when put in the case, then the case is faulty.

  5. Hi I have the i12 earbuds and I have figured out most of my questions with watching the review videos. However I have one thing that is driving me crazy. I am using the earbuds to listen to music but primarily to answer work calls though the Microsoft Teams app. Everytime I get an incoming call my phone starts reading to me the phone number and it always starts with 41 which is weird because our phon numbers never start with 41. It reads me out the entire string of numbers and then after the numbers it rings and it is pretty annoying. According to the instructions it is supposed to beep when I have an incoming call and that does not happen it goes 4 1 7 0 7 5 5 5 1 2 3 4 and it is slow and kinda obnoxious. How can I turn this off and get it to beep or ring instead? PLEASE help. Thank you.

    1. Do this:
      1. Charge the box and pods.
      2. Start with the pods in the case and make sure you have removed the pods from any devices in the Bluetooth settings and “forgotten” them.
      3. Take out a single pod and wait for a few seconds and then tap the touch sensor 4 times.
      4. Put the pod back in the case and make sure it starts charging.
      5. Repeat on the other side.

      Since i12 TWS isn’t the same earphone for everyone (it has different models and different manufacturers), the instructions will be different for every model.

      The above process is the same, you just have to press 5 times or 6 times frequently to change the language. Or in other words, just keep pressing until to hear the word ‘English’.

    1. Hi Wallace! I did experience this with other earphones in the past on my notebook. Some of them were visible when I click on add Bluetooth devices but won’t pair. Meanwhile, some didn’t appear on the scan at all.
      Among the OS, Windows 10 is quite famous for this problem. I was able to fix this problem by uninstalling and reinstalling my Bluetooth driver and then updating it. I also noticed how good the Bluetooth works on the Windows default Bluetooth driver and experience problems when you install the driver provided for the laptop. However, that may not be the solution for everyone. You can read this as well: https://www.thewindowsclub.com/bluetooth-devices-not-showing-windows

    1. Well, by default, they are arranged like that (left one on the left side, right one on the right side) in the case. Moreover, R and L are also written inside the case lid.
      When you pair them together, the blue LED light will be visible on the left one.
      If both are working, you can do the sound test in PC to detect which one is the Left and right. Or even do a stereo test on a youtube.
      You can differentiate each of the earphones by its function as well.

      1. Hi Aynn!
        2 to 3 times after completely charging both the earphones and the case.
        As I said, i12 TWS isn’t some earbud registered to a specific company, lots of Chinese earphone manufacturers make it and both the charging time and battery life of case and earbuds are different in different i12 TWS models.
