Aueky EP T21 Left earbud not working

Had the earbuds for less than two weeks and have not had any issues until now. Today the left earbud is refusing to work. No signs of life except a red light that flashes for a second when I put the earbud back in the case. No matter how long it stays in the case, and if the case is connected/charged, the green light never appears and out of the case, the earbud is unresponsive to touch and no sound comes of it although the right one is connected to a Bluetooth device and works correctly.

I looked through the forum but haven’t found a sensible solution. Help, please.

PS could someone maybe at least explain what the single brief flash of red light means when I put the left earbud in the case. It is the only thing that the earbud does. I know it’s probably not charging because when the right one is charging the red light is on for like a minute (or green light if it’s charged).

The single flash of red light is not in the manual so not sure what it means. Thank you in advance.


Hi @Arigaia

Sorry you’ve experienced this issue. I’ve asked our technical team to get back to me about this so I can advise what to do.

I had the exact same issue except there’s no light at all

Sorry to hear you’re having issues too. It seems best to contact if you’re unable to find any suitable troubleshooting methods here. :pray:

I am having this exact issue too, but with my right earbud.

Did you ever fix it?

Did you find out what the problem was? I’m experiencing the same issue

Yep…almost exactly the same issue.
Bought mine from Amazon in September…it’s now Thanksgiving. The earbuds paired just fine, and performance has been good.
After every use (I really just use them for work with my phone, and on my iPad) they go right back into the case. Recharging has never been an issue.
A few days ago, the left earbud ran out of juice…the right one kept going.
Put them both back in the charger overnight…took them out this morning. The right earbud works…the left one doesn’t
NOW here’s where it gets interesting… while they’re in the case the green light on the RIGHT one will come on as soon as it’s back on the magnetic holder. But the LEFT one only shows the amber light. SOOOooo I lifted the end of the earbud and waited a sec…dropped it back into its nest…VOILA the green light came on and it now seems to be charging.
I THINK that there’s some kind of instability with the magnetic contacts…maybe something comes loose that disrupts the charge.
Anyway, I’m going to watch this and see if the left earbud starts working again.

Left earbud not working solid green light staying on all time

I have the same issue and my left earbud has no light at all.

My EP-T10 Left earbud has not been charging in the wireless case whereas the right one is acting perfectly, would there be a fix for this? (I have tried charging the case fully and taking the earbud out and putting it back in many times but the left one refuses to charge and no light at all)

I have the same problem but with the right earphone, anyone fixed this yet?

I am having the same problem. Left bud does not connect. Only right bud connects to device and is audible.

For me it helped to put the working bud into the case first, wait a few Seconds and then put the one in that wasn’t working :slight_smile:
