MM 450
The MM 450 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) 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.
NoiseGardTM
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 is electronically filtered
out, only allowing the voice of the other person to pass through the
headset clearly.
