MM 550
The MM 550 is an accessory which allows for wireless music enjoyment
when used with mobile phones or other Bluetooth devices/Bluetooth
compliant devices. Its circumaural, closed design and the latest active
noise compensation technology (NoiseGard) make the MM 550 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 550 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 550 to
communicate with your Bluetooth enabled device (e.g. mobile phone, MP3
player, PC or PDA) within a range of up to 10 meters.
SRS WOW HDTM
SRS WOW HD improves the dynamic audio performance of compressed
and uncompressed audio by expanding the size of the audio image
and creating a deep, rich bass response. The patented techniques in
SRS WOW HD widen the horizontal sound field and raise the vertical sound
image, retrieving information lost in the mixing process to create a more
natural audio experience.
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 550 has a TalkThrough function, which allows you to communicate
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.
Additional features
·
Great for travel: comfortable, rugged and foldable headset construction
·
Optional connection via audio cable for music enjoyment without
Bluetooth technology
·
Outstanding sound quality due to Duofol diaphragms
·
Optimum protection against ambient noise due to active and passive
noise attenuation
