  1. Returned 1st set after failing to charge. Replacements have same problem. Never buy these again.

  2. Does the left earbud not function if the right one is turned off? Sometime I only want one earbud in and that only seems to work with the right side.

    1. The right earbud is the ‘main’ earbud. It will function on its own. The left one will not function without the right one.

  3. SAYA BELI JBL TUNE 120TWS (BARU) TAPI YANG KANAN LAMPU LED GAK BISA NYALA DAN GK BISA CONNECT.
    english: I BUY JBL TUNE 120TWS (NEW) BUT THE RIGHT LED CAN’T ON AND CAN’T CONNECT.

  4. The Samuel side does not work nor does the light bulb come on
    לא עובד צד שמואל וגם לא נדלק הנורה

  5. T120TWS is used for talking on the phone. Why is the sound very low, I can’t hear conversation, I don’t know how to adjust?
    T120TWS ใช้สำหรับคุยโทรศัพท์ ทำไมเสียงเบามากไม่ได้ยินเสียงสนทนาไม่ทราบว่าต้องปรับอย่างไร

    1. Too true Daphne
      I have put mine out with the trash
      they are hopeless
      waste of time and money
      Very disappointed!!

    2. Straight into the bin
      they are hopeless
      waste of time and money
      Very disappointed!!

  6. Hello, do you know if the led lights in the box are always on?
    Hola, sabes si las luces led de la cajita quedan siempre prendidas?

  7. Works great with no complaints as soon as the connection is established when the case is taken out i.e. in a second of use ready. I guess commenters have too many moving parts on the handset. Ready to use with one touch.
    Toimii loistavasti ei mitään valittamista samantien yhteys muodestuttu kun kotelosta ottaa pois eli sekunnissa käyttö valmiit. Taitaa kommentoijilla olla liian monta liikkuvaa osaa luurissa. Yhdellä painalluksella käyttövalmiit.

  8. The left earphone does not turn on, how do I connect it?
    El auricular izquierdo no enciende, como lo conecto?

  9. I also have the problem that only the right one does not work the left. where is the problem ????
    Habe auch das Problem das nur der Rechte funtioniert der Linke nicht. wo liegt das Problem ????

  10. The horror of headphones fails to pick up a Bluetooth connection request
    זווע השל אוזניות לא מצליחות לקלוט בקשת חיבור בלוטוס

  11. Right side is fully charged, but it’s always auto turn off by itself. Had doubled checked the battery is fully charged.

  12. I have the left earphone which does not light up anymore, even in the case the light does not come on anymore

    J’ai l’écouteur gauche qui ne s’allume plus, même dans le boîtier la lumière ne s’allume plus

  13. The left earbud does not turn on, not even the light, even when charging. The right perfectly. What can happen to it?

    El auricular izquierdo no se enciende, ni siquiera la luz, incluso estando cargando. El derecho perfectamente. ¿Qué le puede pasar?

    1. check if the charging pins of your earphones are not blocked down, this is very common

      regarde si les pine de charge de tes ecouteur ne sont pas bloquer vers le bas , c’est très frequent

  14. the right earbud makes a random sound, like a jingle, don’t know why … can’t find an answer.Plus they don’t want to charge. when i plug in the box nothing happens. And the end of the cable barely fits into the port, even if you force it …

    l’écouteur droit émet aléatoirement un son, comme un jingle, je ne sais pas pourquoi… je ne trouve aucune réponse. De plus ils ne veulent pas charger. quand je branche le boîtier, rien ne se passe. Et l’embout du câble rentre à peine dans le port, même en forçant dessus…

  15. After about 30 minutes of playing, the left handset starts to signal discharging, in another 30 minutes again and more often, after about 1.5 hours the left one turns off, after putting it in the box the right one charges and goes out, the left one is still lit, it seems to me that it is insufficiently charged. Age of headphones 2 months, played max 12 hours. It is normal? thank you for answer

    Po cca 30 minutách hraní levé sluchátko začne signalizovat vybití, za dalších 30 minut znovu a častěji,po cca 1,5h se levé vypne, po vložení do krabičky se pravé nabije a zhasne,levé svítí stále,přijde mi že se nedostatečně nabije. Stáří sluchátek 2 měsíce, odehráno max 12h. Je to normální? Děkuji za odpověď

  16. aimar the right earbud also makes that random jingle sound ( for me sounds more like four guitar sounds) at least two times when charged which is really annoying to the point that I bought Jbl Go Air earbuds that don’t have that problem.

  17. Hello I have a question. She can no longer charge me. Does anyone know why?

    Hallo ik heb een vraag. Ze kunne bij mij niet meer laden. Weet iemand waarom?

  18. Rarely have I regretted so deeply when purchasing a product. It doesn’t connect with the cell phone, when it stops working on its own. a real tragedy

    Raras vezes me arrependi tão profundamente na aquisição de um produto. Não conecta com o celular, quando o faz para de funcionar sozinho. Uma verdadeira tragédia

  19. Nothing is heard from the left headset even when connected
    Vasemmasta kuulokkeesta ei kuulu mitään vaikka on yhdistetty

  20. My left earphone is frozen on the blue light and it doesn’t do anything anymore, I can’t connect to it anymore. It no longer emits sound. The law works but given the price of these headphones I start to half panic, especially since there is no explanation for this “problem” on the internet.
    Mon ecouteur gauche est figé sur la lumière bleu et il ne fait plus rien, je ne peux plus me connecter a celui ci. Il n’émet plus de son. Le droit marche mais vu le prix de ces écouteurs je commence a paniquer a moitié surtout qu’il n’y a pas d’explication a ce “probleme” sur internet.

  21. No sound from right ear bud. It was working alright but all of a sudden there is no sound. But left one is OK

  22. These are worthless, don’t stay in my small ears no matter which size cover I use. Could not get it to pair with my Samsung phone – never had that issue with any other Bluetooth device.

  23. intermittent disconnection. can only listen for about 2-5 minutes???
    ngắt kết nối liên tục. chỉ nge được tầm 2-5 phút???

  24. Terrible! Not connecting already tried everything
    Verschrikkelijk! Maakt geen verbinding alles al geprobeerd

  25. Jbl tune 155tws the sound keeps dropping out “on the right, if you put it in the ear, at first, just put the ear in and press it not too hard, then for about 2 minutes it left the ear and I put it in again and the sound broke”
    Jbl tune 155tws suara terus putus” seblah kanan kalau di masukin kedalam telingan awalnya cuma masukin keteling masukin kedalam nekannya gak juga terlalu keras lalu sekita 2 menitan lepas dari telingan dan saya masukin lagi timbul suaranya putus” terus

  26. Why can’t the left JBL tune 120 TWS connect even though I’ve followed the guide
    Why are you?

    Kenapa JBL tune 120 TWS yang kiri gk bisa connect padahal sudah ngikuti panduan
    Kenapa kak emangnya?

  27. The right earphone does not charge well, it makes false contact, it hardly moves it stops charging, it does not fit well in my ears, and the sound is very basic, not recommended
    El auricular derecho no carga bien, hace falso contacto, apenas se mueve deja de cargar, no calzan bien en mis orejas, y el sonido muy basico , nada recomendable

  28. The earphones automatically switch off after an hour, how can I change that?
    De oortjes gaan standaard na een uurtje alweer uit, hoe kan ik dat veranderen?

  29. How long should I chage them when fresh out of the box? And do i charge them using the case, or should I plug it in too? The picture instructiins are super useless. Some written instructions would be so helpful.

  30. Is there any way to control the volume? Didn’t see any reference in the manual. Did I miss it?
