Hi,
I have bought a fresh Anker Soundcore 2.
No problem with bluetooth use, with the phone speaker works properly.
Instead I have issue using AUX port with a 3.5mm cable: audio is very, low hardly noticeable, with some interference (despite an high volume from external source, a portable MP3 player that I use often without issue with a JBL Flip Speaker).
How fix it?
Thanks
Alessandro
