MM 450-X
The MM 450-X is an accessory which allows for wireless music enjoyment
when used with mobile phones or other
Bluetooth
devices/
Bluetooth
compliant devices. Its supra-aural, closed design and the latest active noise
compensation technology (NoiseGard) makes the MM 450-X 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-X complies with the
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-X to communi-
cate with your
Bluetooth
enabled device (e.g. mobile phone, MP3 player,
PC or PDA) within a range of up to 10 meters.
apt-X
With apt-X audio coding, you can be assured of crisp, pure and full stereo
sound. It allows you to not only hear, but experience and feel the audio as
it was intended. Utilizing apt-X,
Bluetooth
technology can now offer wire-
less audio quality that is indistinguishable from the highest quality wired
connection.
From major public broadcasters to film production studios, apt-X is used
throughout the world to transmit high quality digital audio from A to Z in
real-time. It was developed to meet the exacting standards of musicians
and audio engineers who love the exceptional dynamic range and high
fidelity it provides. Now available on selected consumer devices, the apt-X
technology ensures that music lovers everywhere can stream the rich lis-
tening experience that only apt-X can deliver.
NoiseGard
TM
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-X has a TalkThrough function, which allows you to communi-
cate with other people without having to remove the headset. When Talk-
Through is activated, professional quality microphones mounted on the
outside of the headset pick up all acoustic signals in the immediate
vicinity. Annoying background noise is electronically filtered out, only
allowing the voice of the other person to pass through the headset clearly.
