If the top of the headband does not touch your head, move the sliding black block
on each side of the headband so that the headband rests on top of your head.

Earpad Design and Replacement
The HE400se earpad is a beveled design with varying thicknesses to conform to
the human head. Should you need to remove and reinstall the earpad (i.e. for
replacement) keep the thinner part on the front side of the ear cup and thicker
part on the back. Fit the mounting flange onto the rim of the ear cup. Then
press around the mounting flange to make sure the earpad snaps into place.

Set-up and Operation
To obtain optimum performance, please allow at least 150 hours of
constant use for break-in of your new headphone. This break-in
period does not have to be at high volume.
The connectors utilize 3.5mm mini plugs on the headphone side.
Push the connector straight onto the socket. Repeat the process with
the other mini plug connector.
The supplied cable adapter with the large
¼
” (6.35mm) jack is con-
nected with the typical headphone output of an amplifier or even
better with a headphone amplifier. Please be aware that many home
amplifiers will switch off the loudspeaker output when a headphone
is connected.
To clean your headphone, please use a soft, slightly damp cloth only.
Do not use any detergents and make sure not to let any fluid enter
the open sides of the headphone. The leather headband can be
maintained using standard leather care products. When your earpads
become worn and no longer offer a good connection to your head,
you should replace them with new ones which can be supplied from
your dealer, or head-direct.com. Note: The internal drivers do not
require maintenance. Any attempt to remove or modify them will
void your warranty.
