I just bought the jbl 120tws but after fully charging the right earbud doesn't work so I can't pair it. Anyone have an idea what I could do? The left one works, but it's not much use if the right one doesn't show blinking lights to be able to pair. Taking it in and out of the box doesn't work either. And after about 5 seconds holding down the button it doesn't work either.

Why does the device allow you to connect to media, as well as contacts, but not calls? The music is buzzing, but that's where it stays and the device goes into recovery. The feature of both "hands-free calls" in these is ...?

kiisseli67 12-10-2020
For handsfree calls, you can either press the right handset once when the call comes in, or turn on the phone from the app to turn on auto answer when the phone is connected to a bluetooth device. For example, in a Samsung phone, it takes about 2 seconds to transfer the call to the headset.

In the beginning I could double click on the snail and Siri started but since a few months back from niar it did not. How do I get the function back?

I got these headphones today. After taking i j from the box, turn it on and pair it, OK. However, after a while of listening, the left earpiece either disconnects and you have to reconnect it, or it disconnects and turns off and then, when turned on again, it connects to the other one, but after a while it turns off again. What should I do?

If the caps are in the case, shouldn't the lights be off too? (First turn off the earbuds)

Does anyone have an answer to this. I have the jbl tune 120TWS but when I want to use my earphones only the right one works. The one on the left also has no light at all. So does anyone know how to fix this? I've held the earpiece for a few seconds, then took it out of the charging case again. But nothing helps.

Hi, I had this too in the beginning. First turn it off completely and turn both on. I myself thought that you only had to press 1 to switch them both on... Not so...

I had this problem, with an ear cleaning stick I moistened it with a little bit of alcohol, very little, clean the contacts of both the box and headphones, you sink a little and loose the contacts in the box and it seemed to me that this makes it fit again the contacts and thus began to load again. I hope it serves you as well.

Unfortunately, this type of listening didn't really happen to me. I keep having problems with him…. I wanted to use it for an Iphone, but every single day, I do 10-15 minutes before I fix them. One of the listeners either didn’t push properly or the listener of the listener went to tonk because about 5 minutes of music one goes off. All this is uncomfortable because I used to buy it maybe 6 times. So I suggest that everyone choose a more serious manufacturer and a more serious, reliable one.

For example, in my case, the right earphone does charge, but when I want to use it, the earphone doesn't last for 10 minutes. I have to be moving it for it to load. But I've been with this flaw for a while. I have to move the headset when it is in the case for it to charge properly. But I don't see any results whatsoever

For example in my case the right earphone does charge but not completely. When I put it in the case I have to be moving it to charge. But when I want to use it, the battery does not last 10 minutes because it turns off right away. I already cleaned them from where they connect. Some time ago I loaned them to a person and he told me that the same headset fell into the water. But after that accident, they did carry me well.
