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.
IN EAR MANAGEMENT
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.
