Good evening, my name is ***** ***** I will assist with your query today.
I assume you have plugged your headphones into the 3.5mm jack at the front, located towards the bottom left of the unit? Unfortunately this is an audio input for MP3 players and other devices not an audio output for headphones.
There is no headphone jack on this unit.
Good afternoon, I havent heard from you recently, and just want to follow up to see if you still required assistance?
