this product 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 this product 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 using this product and have your hearing checked by your doctor. To protect your hearing
when using a headset, some hearing experts suggest that you:
1. Set the volume control in a low position before putting the headset on your ears and use as low a
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.
