we are sorry to hear that. Do you refer to the headphone jack of the Beatpad or of your Android device?
I have the same problem.
Device: Sony xperia Z5c (android 7.1.1)
Mixer: Reloop Mixon 4
Problem: No sound from headphones.
I have this same issue
Android tablet plugged Into beatpad 2 and headphones plugged into the front of beatpad 2 using the 3.5mm jack
Nothing I do seems to let me hear headphones to cue tracks
Taking the piss have not been able to use the gear I brought properly yet so far becoming the worst 450 pounds i have spent
