INSERTING THE EARPHONES  
If the earphone seems to be lacking in low frequency response  
(bass), check the tightness of the seal between the earphone and  
your ear, or try one of the other sleeve options.  
Warning: Do not push the earphone sleeve beyond the ear canal opening.  
To change earphone sleeve, twist and pull sleeve to remove it from the nozzle.  
Push new sleeve onto nozzle until you feel it slide completely over barb. If any part  
of the nozzle is exposed, sleeve is not properly installed. Replace sleeves if they do  
not grip the nozzle tightly

MAINTENANCE  
Careful maintenance ensures a tight seal between the sleeve and nozzle,  
improving sound quality and product safety.  
Keep the earphones and sleeves as clean and dry as possible.  
To clean sleeves, remove them from earphones, gently rinse in  
warm water and air dry. Foam sleeves require a longer drying  
time. Inspect for damage and replace if necessary.  
Ear sleeves must be completely dry before reusing.  
Wipe the earphones and sleeves with mild antiseptic to avoid  
infections. Do not use alcohol-based disinfectants.  
Do not expose earphones to extreme temperatures.  
Replace the sleeves if they do not fit properly.
