Proper Fitting

The advanced suspension system of the DC ONE-X is designed for a simple

and comfortable ﬁt. Proper ﬁt is necessary for maximum effectiveness. The

headset should be worn so that the head pad lightly touches the top of the

head. Adjust the sliding assembly on each side as necessary (see Fig. 1),

to ﬁt your personal comfort preference.

The ultra-soft memory foam of the ear seal will conform to the sides of your

head to provide an adequate seal. While in the presence of noise, turn on the

ANR circuitry and then adjust headset accordingly for optimum performance of

communications and music listening.

To adjust microphone placement, move boom up/down and in/out by

rotating and ﬂexing the boom as necessary. Ideal microphone placement is

1/8” from the lips, as this will provide maximum intelligibility and ambient

noise rejection.
