frayed or damaged.

rain, liquids, or excessive moisture.
You suspect the headset needs service 
or repair.
You want to clean the headset.

Permanent hearing loss may occur if a 
headset is used at high volume. Set the 
volume to a safe level. You can adapt over 
time to a higher volume of sound that may 
sound normal but can be damaging to your 
hearing. If you experience ringing in your 
ears or muffled speech, stop listening and 
have your hearing checked. The louder the 
volume, the less time is required before 
your hearing could be affected.

Hearing experts suggest that to protect your 
hearing:

Limit the amount of time you use the 
headset at high volume.
Avoid turning up the volume to block out 
noisy surroundings.
Turn down the volume if you can't hear 
people speaking near you.

Due to the physical nature of battery, the 
charging time may become longer and the 
actual capacity of battery may decrease. If 
you have any questions regarding the 
replacement of the built-in battery, please 
contact our service center.
