WARNING

SPECIFICATIONS

the arms

Fold the ear pads inward

Before using this unit, make sure to read the instructions below, and the Owner’s Manual.

In the interest of personal and public safety, never wear the headphones while operating any 
type of vehicle.

Do not use the headphones in a location where safety requires that you be able to hear the 
sounds around you (such as on a train platform, at a railroad crossing, in a factory, or along a 
busy road).

CAUTION

Using headphones for an extended time at high volume may damage your ears or negatively 
impact your hearing. Such use will also strain the headphones themselves, so please enjoy them 
at an appropriate volume.

When using headphones while on public transportation or in a public place, please be aware of 
the possibility of annoyance to people around you.

Always handle either the headphones themselves or the plug, not the cord. This will help in 
maintaining the electrical integrity of the cord by preventing any damage to it.

When connecting the headphones, always have the volume on the unit you are connecting them 
to turned down to the minimum. Damage to the headphones may occur otherwise.

Protect the unit from strong impact.
(Do not drop it!)

Do not expose the unit to direct sunlight, place it near devices that radiate heat, leave it inside an 
enclosed vehicle, or otherwise subject it to temperature extremes. Excessive heat can deform or 
discolor the unit.

When the headphones need cleaning, wipe them with a soft, dry cloth.

Should you remove the plug, keep it in a safe place out of children’s reach, so there is no chance 
of it being swallowed accidentally.

Always pay attention to your children so they do not wear or play with the attached carrying 
pouch.

If you experience any abnormality in the skin area contacted by the headphones, immediately 
stop using them.
