How to share your music
Short answer
Connect your audio device to your headphones via Bluetooth. Connect another pair of headphones to your Mid A.N.C. headphones by using a 3.5 mm cable.
Let a friend connect their headphones to the 3.5 mm AUX port on your Mid A.N.C. and listen together.
Ensure that Mid A.N.C. is connected to your sound source via Bluetooth.
Connect the 3.5 mm jack of the other headphones to the 3.5 mm AUX port on Mid A.N.C.
