Earbuds not working after one day?

The left earbud of my EP-N5 is not working - after 2 hours. I got the buds yesterday (24.12.2020) as a x-mas gift. The right earbud works fine, syncs immediately, no issues. I have attempted to troubleshoot the earbud as directed in the manual. Nothings was helpful? What can I do?

Did you charge them fully before you started using them?

Hi thanks a lot for your help.
Yah. I did. :slight_smile:

I did what stonefly mentioned in his post. This worked for me:
It was such an absurd experience.
I tried charging it outside, not just putting it in the case.
Just 2 seconds

1 : Yellow -(ground)
2 : Red +
3: NC
4: Black -(ground)

Now they are working again.
Hope this is helpful for someone. I was for me.

Kindest regards

How do you charge it out of the case? I need to charge the right side I already replaced mine twice and had the same issue with all three of them. My brother has a pair too but has never once malfunctioned. I think he mentioned something about mine being different from his but I don’t know.

재미있죠 2초도 아나고 그냥 아주 잠시 전원 연결 해 주면 살아 납니다.
케이스에서 충전도 잘 되고…

It’s fun, you don’t even need 2 seconds. Just plug it in for a while and it will work.
Charging is well done in the case…

Maybe there is a bug in the firmware. Samsung’s Buzz Live product had a firmware update due to a similar problem.
