Hello!
Recently bought the earfun air 4 pro and they are amazing but they will not go into mono when only one earbud is in, ive been told this is a capability but i cannot seem to get it to work
Using a nothing 2a for the device if that helps at all
Thanks!
To assist you further, please email your order number to our customer service team at:
service@myearfun.com
We'll address your concern promptly once we receive your details.
Mono mode only works if you disable all high quality codecs in the app. As soon as you have any of the highter quality codecs, like aptx, enabled, mono mode will no longer work.
