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.

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, e.g. from turbine engines, is electronically filtered out, only allowing the voice of the other person to pass through the headset clearly.
