Is there a way to EQ the headsets to where it cuts out some of the openness?

There are three ways that can improve the sound.

1. Putting the mic closer to speaker's mouth.

2. Turning on the ENC function. You are advised to turn on the ENC function during the running time, and it will not affect the running time of the device.

3. Pressing the "+" button on the side of headsets.

The ENC function would be helpful while you are in a noisy environment.
