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 HD™

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 1kHz ) 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 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.

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

SRS WOW HD

Remarkable enhancement for mono and stereo playback

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. SRS WOW HD also shapes a maximized bass response using sculpted filters and driver physics to go beyond the low-frequency limitations of speakers and headphones. SRS WOW HD also adds Definition™ Control, for realistic clarity, and the new Center Control, for dynamic extraction and positioning of dialog.

Immersive 3D audio

SRS WOW HD adjusts the space of the stereo image and eliminates the narrow stereo sweet spot and creates an immersive stereo image from mono and stereo source material. It also restores audio realism which is often masked by traditional recording and playback techniques.

Center Control

SRS WOW HD adjusts the mix of the center information into the stereo image. It works in tandem with the space control to create the perfect balance, acting as a "zoom" lens for sound. It can bring content to the forefront to dominate the mix or fade it backward, virtually eliminating the content all together.

Optimal headphone listening

SRS WOW HD includes techniques based on patented HRTFs to deliver a natural, non-fatiguing headphone listening experience by placing the perception of the stereo sound image outside of one's head making it more realistic and immersive.

Elevated sound image

SRS WOW HD adjusts the horizontal plane of the audio image from non-optimally placed speakers placing it at an appropriate listening level.

Definition Control

SRS WOW HD delivers a livelier, more brilliant sound. The purified sound can be heard in musical vocals, high-frequency instruments, and exposes details of ambient sound present in the audio source.

Bigger bass

SRS WOW HD includes psychoacoustic bass enhancement techniques which enhance the perception of low bass frequencies from speakers and headphones which, under normal conditions, can not produce these frequencies due to the inherent low frequency cut off and driver size limitations.

Audio level management

SRS WOW HD includes an audio level management system which monitors the output levels of the entire product audio system and manages the level dynamically to prevent sudden audio clipping.

Features of SRS WOW HD

• Stereo enhancement which improves dynamic audio performance
• Sculpted bass response for maximum thump on small speakers
• More natural audio with a wider sound field and raised sound image
  High-definition control for realistic clarity
  Center Control for dynamic extraction and positioning of dialog
