Ensemble Overview - Buttons & Indicators
There's a pole at the back of the AUX Input from TV that you can use to Factory Reset the Ensemble headphones. Screwdriver or other narrow tool required.
Note 1.1: For Batch Numbers T22J1 and later (T22L1 if you purchased an individual pair of headphones), the ON/OFF switch and pair button will look slightly different. See pictured below. Where to find the batch number.
Note 1.2: Starting from Batch number T23D1(23F1 for single AS50 headphones), the charging port on Ensemble has been changed to a Type C port. The type C transmitter can't charge the AS50 headphones with a micro USB port, yet the transmitter with a micro USB port can still charge the AS50 headphones with a type C port.
Note: The Play/Pause and next/Previous track only work when the headphones are paired with a mobile phone.
