Precautions

High volume may affect your 

hearing. For traffic safety, do not 

use while driving or cycling.

 Because the headphones are of a high 

density enclosure, forcing them against 

your ears may result in eardrum damage. 

Avoid using the headphones where they are 

liable to be struck by people or other 

objects, such as a ball, etc. 

Pressing the headphones against your ears 

may produce a diaphragm click sound. This 

is not a malfunction.

Optional replacement earpads can be 

ordered from your nearest Sony dealer.
