around you while listening to music.

children.

before connecting the product to it.

places, keep the volume low so as not to
disturb other people.
●Minimize the volume on your audio device
before connecting the product in order to avoid
hearing damage from sudden exposure to
excessive volume.

you may feel a tingling sensation in your ears.

near heating devices or in a hot, humid or dusty
place. Do not allow the product to get wet.
●Be sure to purchase the appropriate
conversion plug adaptor when connecting

separate extension cable available from your
dealer.
