I don't know. I've never attempted to use headphones. However, the instruction manual states that there is an auxiliary in-line jack for connecting your iPod, MP3 player or other digital music player. Connect the headphone jack of your external device to the AUX IN jack on the player. Turn on CD player and it will enter the AUX function mode once your external device is plugged in to the AUX IN jack. Start to play your external music device. Adjust both volume controls. When done listening, turn off your external music device and the CD player and unplug the AUX IN jack. (Once the AUX IN Jack is plugged the CD player will automatically enter the AUX mode). I don't understand any of that, but if it answers your question, have at it.
Thank you for your speedy reply. However, I don't know if I should order the item. I need three for my classroom. However, headphones are necessary so the children do not disturb the other children. Could you possibly contact the company?
