AirPod MAX with MDAC NANO

[Ani]

Hi I was using previously B & W PX along Audio lab MDAC NANO & iPhone , few months back i shifted to Airpod Max and i didnt used MDAC NANO, yesterday i tried to connect MDAC nano via Bluetooth to iPhone and connecting one end of the 3.5 Cable to mADC nano then another end with Aipod MAx through lightning to 3.5 ! But no sound. Can some one suggest me if any one used MDAC NANO with Airpod MAX. Airpod max doesnt have 3.5 slot so no option but to use the lightning to 3.5 .
