Eartip Fit Testing
A good way to gauge whether or not the eartip is sealing properly
in your ear canal is by snapping your fingers right next to your ear. If the
seal is proper, your ear will not feel "plugged," yet the snapping of your
fingers will sound dull and distant. If you hear your finger snaps distinctly,
the seal is probably not adequate. If the sound of your finger snapping is
dull and distant, but your ear feels plugged up, like you're on an airplane
preparing to land, then you've over-inserted the eartip.
Using Tour on Flights or at High Altitudes
™
When using Tour at different altitudes, the air pressure within your ears
may change, thereby changing the sound that you hear from the
headphones. This is especially true with the gains and drops in altitude
during airplane travel. To help with this, occasionally break the eartip
seal and re-insert your Tour headphones into your ears. Another helpful
tip is the common exercise of holding your nose and very gently
blowing through it, which can relieve some of the pressure in your ears.

Cleaning the Eartips
Keeping your Tour eartips clean is essential for safe, hygienic use.
™
IMPORTANT: DO NOT attempt to clean the eartips without first removing
them from the headphones. Getting the delicate circuitry inside your
Tour headphones wet may cause permanent damage.
1. Firmly grip the eartip with one hand and the earphone with the other.
Carefully remove the eartip from the eartube.
2. Use warm water and mild soap on a damp cloth to remove dirt
and earwax from the eartip. DO NOT use harsh cleaning agents.
3. Rinse and completely dry your eartips before placing them back
on your headphones.
4. Carefully push the eartips back onto the Tour headphones,
making sure they are on the eartube completely.
