ipad to soundbar wireless - but can i use headphones without interrupting the wireless????

hi guys.... im stuck on a problem

i am connected via bluetooth to my soundbar using my ipad.. BUT... i want to connect my headphones to the ipad so i can DJ from the Djay2 app, it has split output in the Djay app so thats good but of course as soon as i put the headphones in the ipad to start mixing the headphone jack must over ride the bluetooth connectivity and it stops transmitting to the soundbar through bluetooth and the sound starts in the headphones.

My question - can you play through bluetooth and have headphones in at the same time??? there must be a way??????
