A decibel is a unit of sound measurement that increases exponentially with volume. For example, conversational speech is typically around 60dB, and a rock concert in a stadium is often about 110dB.

90dB 8 hours

95dB 4 hours

100dB 2 hours

105dB 1 hour

110dB 30 minutes

115dB 15 minutes

120dB Avoid as damage may occur

IN EAR MANAGEMENT

EARTIP FITTING AND SELECTION

Selecting the correct eartip for use with VISO HP20 will have a major impact on sound quality. With a proper fit and seal, the listener will be isolated from unwanted noise. Bass response will be more pronounced and tonal balance more defined with a comfortable secure fit.

To find a fit for everyone, NAD supplies an accessory package filled with various shapes and sizes of eartips for finding the perfect fit.

• From smallest to largest, test out each eartip to find the best seal

and most comfortable fit for the size and shape of your ear canal.

• Also make sure the headphones will stay in the ear and not fall out

while being active, like running or cycling.

EARTIP INSERTION AND REMOVAL

1 Holding the right in-ear monitor in your right hand, pull up and back on the outer part of the ear to open the ear canal. Carefully insert the right in-ear monitor (rubber tip first) to create a complete and comfortable seal inside the ear.

2 Repeat these steps with the left in-ear monitor.

3 When done listening, slowly twist the eartip from the ear canal to

break the seal and remove the in-ear monitors.

WARNING

Do not insert the eartip deep enough to plug the ear as this could result in permanent damage to the ear canal.

FITTING TIPS

To know whether the eartip is properly sealed within your ear, insert the eartip into the ear canal and try listening to ambient noises with no music playing.

• If there is a proper seal, the sound will be dull and distant.

• If the sound is clear, the eartip is not properly sealed inside the ear.

• If the sound can faintly be heard in the distance but pressure is felt inside the ear, the eartip has been over-inserted and must be readjusted.

PROTECTING YOUR INVESTMENT

For long lasting enjoyment of your headphones, you should respect their limits and avoid excessive volume levels for music or movie playback.

• Excessive volume levels can damage all headphones.

• If your headphones are pushed to excessive volume levels, they might be driven into “clipping”, which could result in severe and/ or permanent injury.

• If using your headphones at loud levels, listen carefully for any sign of harsh, garbled midrange and diminishing intelligibility – and if detected, turn the volume down immediately.
