Ultimate Ears F1 19 PRO manual Sound Level Attenuator, Extension Cable

SOUND LEVEL ATTENUATOR

When using your earphones with an unfamiliar or unstable sound system (airplane, public access ports, etc…) make sure volume is low and is kept at a moderate level to prevent “break-in” bursts of loud sounds. For these environments, we recommend use of the sound level attenuator to aid in buffering unusually high sound output.

To use the sound level attenuator, insert the 1/8 inch input plug at the end of your earphone cable into the sound level attenuator and then plug the attenuator into the listening device.
