EP-EX10A earbud

Design and specifications are subject 

to change without notice.

  This microphone is a precision 

instrument. Never disassemble it.

  Do not expose the microphone to a 

mechanical shock such as by 

dropping or striking it.

  If the microphone is placed near 

speakers/headphones, a high pitched 

noise may be heard (howling effect). 

This is caused by the microphone 

catching sound from the speakers/

headphones repeatedly. In this case, 

place the microphone as far as 

possible from the speakers/

headphones.

  Do not leave the microphone in a 

humid, dusty or hot place, or under 

direct sunlight. This may cause a 

malfunction.

  When using outdoors, never let the 

microphone become wet with rain 

or saltwater.

  When the microphone and the plug 

become dirty, wipe them with a dry 

cloth. Do not blow on the 

microphone when dusting it. A dirty 

plug will cause deterioration of 

sound quality and intermitted 

sound.

  Always hold the plug when 

disconnecting. Pulling the cord may 

cause it to snap.

  Clean the earbud by hand-washing 

with a mild detergent solution. 

Remove the earbud when you clean 

it. After cleaning, dry the earpiece 

well before use.

  The earbud may deteriorate due to 

long-term storage or use.

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 microphone.  

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.
