Exposure to high volume sound levels or excessive sound pressure may cause 

 

temporary or permanent damage to your hearing. Although there is no single volume  

 

setting that is appropriate for everyone, you should always use your headset with the  

 

volume set at moderate levels and avoid prolonged exposure to high volume sound  

 

levels. The louder the volume, the less time is required before your hearing could be  

 

affected. You may experience different sound levels when using your headset with  

 

different devices. The device you use and its settings affect the level of sound you  

 

hear. If you experience hearing discomfort, you should stop listening to the device  

 

through your headset and have your hearing checked by your doctor.

 

To protect your hearing, some hearing experts suggest you:

 

1. 

Set the volume control in a low position before putting your headset on your ear and  

 

use as low volume as possible

 

2.

 Avoid turning up the volume to block out noisy surroundings. Whenever possible,  

 

use your headset in a quiet environment with low background noise

 

3.

 Limit the amount of time you use headsets at high volume levels

 

4.

 Turn the volume down if the sound from the headset prevents you from hearing  

 

people speaking near you
