  1. when i charge them the case (all three dots) start blinking. they turn on, go brighter, then go back and forth between brighter and dimmer. what does that mean?

  2. help when I set up the earbuds I accidentally entered a code and didnt read and I have used the code, now i am trying to reset the password but I have no idea how to. anyone have any idea how to reset the passcode of the tune 125

  3. right earbud stopped working. tried everything listed to resolve problem, but nothing seems to work.

    1. Having the same problem with my left one. Tried factory reset not can’t get it to connect to Bluetooth.

  4. The right bud is connected but the sound is super quiet while the left works just fine. Loud as can be…. I’ve reset them several times. Disconnected and reconnected several times….

    1. You need to clean ear wax out of the ear buds… it has clogged the sound port. Look YouTube videos on how to do it with out damaging units

    1. Try turning them off, while you are pressing the button to turn them back on – Hold till they blink white and blue. then let go- computer should pair automatically at this time. * Insure both earbuds are out of the case and fully charged. Turn off the bluetooth on your phone, if you are still paired and connected to your phone they will not connect to the laptop.

    2. When trying to connect do the ear buds, does the device name come up as Tune125TWSLE?,

      It should display as Tune125TWS and this is the only device that it will connect to.

      I got mine to work by down grading Bluetooth driver in device manager

      Once that was done the device displayed as Tune125TWS and I could connect without a code, hope this helps

  5. I cannot get bot buds to sync only one works. I reset them and reloaded on my Iphone and still same issue. What is the side balance they talk about and mono or stereo mode. Is that a button click or something else. About to send these back, please help.

    1. You can try to turn on the left earbud press for two seconds and then the right earbud for a couple of seconds. You will have to look at the indicator light which becomes blue on both earbuds to see if they are working together.

      The mono mode is when you are using one earbud.

      The stereo mode is when you are using both earbuds.

    1. For pin issue!! try to disconnect from the previous device and then put it back in the case. Next, take out the right one only, and go to the other device’s pair with new device option. you will be able to see the name of the earphone with a headphone sign. Now you just need to pair with it without pin. after you take out the left one, it will be automatically connected. After this process, from next time onwards you dont need to try this method anymore. you can disconnect from one device and connect with the other easily from your saved devices.

  6. I synced the button to Alexa… I would like to change it to Google but am unable to. I tried the factory reset as described above but it still brings up Alexa… help please…

  7. Like others, pin does not work to connect to PC. Will probably return for a different brand.

    0000, 1111 and 1234 do not work.

  8. I have never had so much trouble trying to use bluetooth ear buds. I got them paired once where both were working together, now they won’t, if I try to go into settings and pair the other that is not working the other goes off and the one just paired will work, but the two won’t sync. I am very close to sending them back unless I can get an answer. The print in the instructions are so small it is ridiculous. I thought I would pay a couple extra bucks and get buds from a respected name, I am having more trouble with these than the cheap ones.

  9. When pairing to an iPhone XR, it shows two TONE 125 earbuds to pair, is this correct?

    I can only get left or right to play, not both, can someone help.

  10. If you can’t pair your JBL earbuds with your PC or Android phone just put the earbuds to “pairing mode” (turn off then press the button on it and hold for a few seconds until the LED is starts blinking in white and blue) and then search for Bluetooth devices on PC or your phone to pair. You will see a new device on the list, the name will be a bit different than before (eg. JBL TUNE225TWS Stereo). Select this new device, no PIN code is required to pair.

      1. had paired with samsung s20 fan, turned off like suggested and it connected with a totally different screen on phone making it obvious it had connected…THANK YOU, I almost gave up.

  11. Do these buds can be used for phone conversations to pick up while driving? If so how do I go about it because I seem to not find instructions.

    1. Yes, they can be used for driving. When the call comes through the headset, you will press the button on the left side of the earbud to answer the call. In the event, you have difficulty to answer the call after pressing the button; you can answer the call by your pressing the answer button on your phone and it connect through the earbuds.

    1. You can call the product expert at 1-800-336-4525
      Mon – Fri: 9am – 11pm (EST)
      Sat – Sun: 9am – 5pm (EST)

  12. Seems like I am not the only one with this issue but can someone from JBL please address this issue. Pin numbers on 0000, 1111, 1234 do not work. Can attach to my phones but when I try to attach to my laptop, it doesn’t work. It only prompts for a pin number on my laptop.

  13. Pc requires Pin code to connect and displays both headbuds individualy as JBL TUNE 125WTS-LE. 0000,1111 and 1234 do not work.

  14. I have tried 0000,1111 and 1234 to pair with my CAT phone but it says cannot pair because incorrect pin or passkey??
