How to connect 2 pairs of headphones to a tablet?

Question

Android

Hello! Now I'm on the train and it became necessary to connect 2 pairs of headphones to the tablet to the Samsung Galaxy Tab 2: regular 3.5 mm and Bluetooth. When I plug in regular Bluetooth headphones, they just stop playing sound. It is understandable - a priority in conventional headphones.
Tell me how to make sound play from both headphones? Maybe there are some programs for this?

Answer 1

Just use an adapter where you can plug two headphones
