Note: 

The nozzle contains small parts. Choose a proper work 

surface before disassembly.

1.  Place the nozzle key (included with earphones) over the 

nozzle. 

2.  Turn the key counter-clockwise to loosen and remove the 

threaded collar. 

3.  Pull gently on the nozzle with your fingers to remove. 
4.  Using your fingers only, grasp the end of the nozzle insert and 

gently slide it out.                       

Caution: 

Do not use any tools or your teeth as this could cause 

damage to the nozzle insert.

2.  Insert the nozzle into the earphone, aligning the dots so it 

matches the keyed opening.                  

3.  Place the threaded collar over the nozzle. After ensuring the 

threads are properly engaged, use the nozzle key to gently turn 

clockwise.                       

Caution: 

There should be no resistance to turning the collar 

until  fully  threaded  into  the  housing.  Check  the  following:                         

•  The insert is fully seated in the nozzle. 
•  The nozzle is properly seated in the housing (dots 

aligned). 

4.  Once you are certain that the nozzle is properly seated and the 

collar threaded all the way into the earphone housing, use the 

key to tighten the collar just enough to ensure it will not loosen 

during normal earphone usage.
