Important Hearing Care Information
If, after using your Westone CR-1 Earphones, everything sounds 
muffled, or if you hear ringing or buzzing, your ears are trying 
to give you a warning! These symptoms are normally associated 
with a condition known as Temporary Threshold Shift and are an 
indication of conditions that could lead to permanent hearing 
loss.
While no two individuals’ hearing sensitivity is exactly the 
same, there are established safety guidelines for sound levels 
versus time of exposure. The following chart is based on OSHA’s 
(Occupational Health and Safety Administration) exposure 
information for industry. Remember that these guidelines are 
based on average hearing sensitivity, your sensitivity may be above or below these levels.
The use of any earphone offers benefits and risks. Westone CR-1 Earphones can 
lower ambient sound levels approximately 25dB when properly worn. However, the 
performance capabilities of the earphones can allow the user to negate the benefits of 
hearing protection from ambient sound. We want you listening for a lifetime!
Remember, personal hearing protection is your responsibility!
Insertion and Removal Instructions
Identify the left and right CR-1 earphones. The red dot 
indicates the right earphone while the blue is for the left. 
With your right hand, hold the right earphone so that the 
cable points toward the back of your head. Use your left 
hand to pull up the outer ear while inserting the canal 
tip of the earphone into your ear canal. Slowly rotate the 
earphone counter clockwise into place. 
A light coating of Westone Oto-Ease
®
 on the canal tip of 
the earphone will ease insertion. The earphone should 
almost seem to snap into place. Insert the left earphone in 
the same manner, but rotate it clockwise into place.
Reverse these steps to remove the CR-1’s. For the right ear, 
pull back on the outer ear with your left hand to break 
the seal, then turn the earphone clockwise to remove it. 
Rotate counter clockwise for your left ear.
Caring for your CR-1 Earphones
Here are a few simple guidelines that can greatly increase your listening enjoyment 
and lifespan of your Westone CR-1 earphones.
·  Always store your earphones in the provided case. 
·  In case of poor sound quality due to earwax in the sound bore, use the included wax 
removal loop to carefully remove the earwax. Never use any other object to attempt 
to remove the earwax as this may result in damage to the earphone and will void the 
warranty. 
·  Do not use the cord to remove the earphones from your ears. This may cause damage 
to the cord and result in poor performance. Damage of this nature is not covered by 
the warranty.
·  Do not expose your earphones to temperature extremes. Avoid strong impacts to 
your earphones.
·  Wipe down earphones after each use and never immerse them in water.

Please Note
These CR-1 earphones were made specifically to fit your ears. Their performance 
depends on a snug fit and firm acoustic seal. Please be advised that any significant 
change in your weight (gain or loss) can result in changes to the shape and/or size of 
your ears and ear canals. This will affect the performance of your CR-1s, not only in 
sound quality, but also in the amount of hearing protection afforded.
If you experience this type of problem, see your hearing care provider or dealer to 
have new impressions taken. Your earphones can then be re-manufactured from the 
existing components to address the fit issue. Charges will apply.
Moisture in your earphones can cause temporary performance issues. Do not insert 
your earphones if your ears are wet. Always dry your ears completely before inserting 
your earphones. Should you inadvertently allow water or perspiration into the 
earphones and they quit working, allow to dry completely before attempting to use 
again. Minor moisture build-up should dry out and not affect long-term performance. 
Extended exposure to moisture or submersion will result in permanent damage (not 
covered by the warranty).
