Digital Infrared Receiver

4.1

Overview

Using the latest electronic technology, the use of

specialized chips to ensure the best performance and

longest battery life, according to ergonomic design

of the infrared receiver to receive IR signals can be

very good. With channel selection functions and

volume level adjustment function, the power switch

control, and battery power, signal indicator, when

the receiver receives less than 5 minutes continuous

signal or unplug the headphones will automatically

shut down after 5 minutes.
