Tips

For best results, connect the transmitter to your TV's optical output if available, as it provides the cleanest digital signal. Adjust the balance control to compensate for any hearing asymmetry, and use the tone controls to boost speech frequencies for clearer dialogue. The docking station doubles as a charger, so always place the headphones back on the dock when not in use to keep them ready for your next viewing session.
