MM 450
MM 450
The MM 450 headset provides undisturbed music enjoyment in noisy environments – even without the constrictions of cables. Its supra-aural, closed
design and the latest active noise compensation technology (NoiseGard)
make the MM 450 especially suitable for use with in-flight entertainment
systems. Due to its active and passive attenuation of ambient noise, it lets
you enjoy music even in noisy environments.
Bluetooth
The MM 450 complies with the new Bluetooth 2.1 standard. Via its
Bluetooth interface, it can be connected to a wide variety of Bluetooth
enabled devices. Bluetooth wireless technology allows the MM 450 to
communicate with your Bluetooth enabled device (e.g. mobile phone, MP3
player, PC or PDA) within a range of up to 10 meters.
NoiseGard
The NoiseGard active noise compensation system is based on the principle
of cancelling out sound using “anti-sound” (phase-inverted sound). Tiny
microphones pick up low-frequency ambient noise (up to 1 kHz) near the
ear. The NoiseGard electronics use this noise to generate a sound wave
which is the exact opposite (IE: at the same level but polarity reversed –
180° out-of-phase), the effect being that the polarity reversed signal
cancels most of the outside noise.
TalkThrough
The MM 450 headset has a TalkThrough function, which allows you to
communicate with other people without having to remove the headset.
When TalkThrough is activated, professional quality microphones
mounted on the outside of the headset pick up all acoustic signals in the
immediate vicinity. Annoying background noise, e.g. from turbine engines,
is electronically filtered out, only allowing the voice of the other person to
pass through the headset clearly.
Additional features
• Outstanding sound quality due to patented adaptive baffle damping
and Duofol diaphragms
• Optimum protection against ambient noise due to active and passive
noise attenuation
• Great for travel: comfortable, rugged and foldable headset construc-
tion with single-sided, detachable cable
• Without the detachable audio cable, the headset can be used as a
passive hearing protector

Connecting the headset to the audio source
CAUTION! Danger of malfunction!
The transmitted radio waves can impair the operation of
sensitive and unprotected devices.
왘 Only use the headset in aircraft where wireless Bluetooth
transmission is permitted or use the audio cable instead
(see “Connecting the audio cable” on page 13).
The headset complies with the Bluetooth 2.1 standard. In order that data
can be transmitted wirelessly using Bluetooth technology, you have to
register your headset with your audio source (pairing).
The headset can save the connection profiles of up to 5 Bluetooth devices
with which they have been paired. After switch-on, the headset automatically connects to one of these devices.
If you pair the headset with a sixth audio source, the saved connection
profile of the first Bluetooth device will be overwritten. If you want to
re-establish a connection with the first audio source, you have to pair the
headset with this audio source again.
If your audio source does not have a Bluetooth interface, use an optional
dongle (see “Accessories and spare parts” on page24). In addition to
adding Bluetooth capability to your audio source, this dongle uses apt-X, a
technology that ensures crisp, pure and full stereo sound. With apt-X,
Bluetooth can now offer wireless audio quality that is indistinguishable
from the highest quality wired connection.
For an optimum listening experience, your audio source has to
support the A2DP profile.
