Tips & Warnings

• The dual plug adapter is designed to reduce the volume on the strong audio signals that are commonly used by airline sound systems. If the volume is too low when using the dual plug adapter, you can plug the audio cord directly into the system’s 3.5 mm output jack.
• Always start with the volume low and increase it to your comfort level. Sudden loud blasts of noise can damage your hearing.
