Design and specifications are subject 

to change without notice.

  Please keep your headphones clean 

at all times especially inside the 

rubber earbud. (see fig. ) 

If any dust or ear wax inside the 

earbud, you may experience some 

listening difficulties.

  Listening with headphones at high 

volume may affect your hearing. For 

traffic safety, do not use while 

driving or cycling.

  The earbuds may deteriorate due to 

long-term storage or use.

  Install the earbuds firmly onto the 

headphones. If an earbud 

accidentally detaches and is left in 

your ear, it may cause injury.

  Be careful not to allow any buttons 

to be unintentionally pressed when 

the headphones with iPod/ iPhone 

connected are in the supplied 

carrying pouch, etc.

In particularly dry air conditions, mild 

tingling may be felt on your ears. This 

is a result of static electricity 

accumulated in the body, and not a 

malfunction of the headphones.  

The effect can be minimized by 

wearing clothes made from natural 

materials.

EP-EX10A is available (sold 

separately) as optional replacement 

earbuds.

EP-EX10A offers 4 types of the 

earbuds: SS, S, M and L.
