Earfun Air Pro 4+ - Latest frmware release notes? - No AP4+ forum here?

Sept 15 2026

Today my Earfun Air 4 Pro Plus got a new firmware update. All it says is 'bug fixes'. Come on, Earfun, give us a better explanation than that! What exactly did you change or fix? Did anything improve? Is there anything new?

These are really good earbuds, but the update info and support are crap. Also there is still no separate forum here for the plus model.

Had the same issue with you guys for the Air 4 Pro (non-Plus) as well. Please do better.

Same Here, Version 1.3.5, But I Haven't Update it Yet

Same here, Version 1.3.5. But unlike you, I updated the firmware.
Result: Right earbud is super low volume. At first while having both earbuds on ears I thought that right wasn't working at all. I only realized it's "working" with super low volume after taking out the left one.

I tried factory resetting, uninstalling and re-installing the EarFun android application, but nothing worked.

How can I fix this?

New Update Coming Version 1 3.7, Maybe U Can Try, Because I Have No Problem For This Version

Updated to Version 1.3.7 but problem was not fixed. Right Earbud still super low volume and sound is muffled. The buttons on the earbud still work.
I tried factory resetting again, after update to 1.3.7 which didn't fix.
What else can I try?

After Update Im Always Do This

1. Delete/Forget Bluetooth Device

2. Reset Earfun (Use Reset with Button At Case) Im Never Reset From Earfun Apps.

3. Connect Earfun Again

Hopefuly Help U,,,

Another day, another update ... that just says 'bug fixes'

This time it is Air Pro 4+ firmware version 1.3.7 

Come on, Earfun, make a channel here specifically for the 4+ and give us proper firmware release notes!

Is the ANc better?
Is wind-noise reduction mode improved?
Have you fixed the audio disappearing from one earburd (until you put them in the case and take them out again)?
etc.

Regarding the EarFun Air Pro 4, please add a toggle in the app to disable the beep confirmation tone specifically for volume adjustments. This tone was already removed in a previous firmware version, which was great, but it was reintroduced in the latest update and is now very annoying when changing the volume. Please let us turn it off."
