Mono / Stereo

The HT381 supports both Monoaural Sound Mode and Stereophonic Sound Mode.

You may use the Mono/Stereo Switch on the back of the transmitter dock to switch between the two modes.

What's the Difference?

Mono sound mode would produce the same exact sound through both earbuds. For instance, if you're listening to something with a violin and a piano, the melody produced by both instruments will come through both earbuds simultaneously.

On the other hand, stereo sound mode allows the melody of each instrument to each come through a different earbud; for instance, violin from the left, and piano from the right... they'll combine together when you hear them through your own ears, producing a stereo-like effect.
