Sennheiser Launches apt-X Compatible Versions of its Best Selling Bluetooth® TRAVEL Series Headsets

May 9, 2012 - PRLog -- OLD LYME, Conn. — May 7, 2012: Microphone and headphone manufacturer Sennheiser announced that it has launched enhanced versions of its MM 400-X, MM 450-X, MM 500-X and MM 550-X TRAVEL Series headsets. The new models are now compatible with the apt-X® codec, which provides enhanced fidelity and clarity whether users are listening to music or making calls.

The apt-X® codec offers audiophile travelers an enhanced Bluetooth® listening experience through the use of proprietary audio codec compression algorithms. Just like the earlier MM models, the new Sennheiser apt-X compatible headsets are compatible with any Bluetooth® enabled device that supports A2DP and HFP/HSP profiles including computers, smartphones and tablets and will benefit from increased fidelity when using with devices utilizing apt-X®.

"The new Sennheiser MM 400-X, MM 450-X, MM 500- X and MM 550-X headsets take advantage of the latest advances the CSR group has made in achieving a Bluetooth wireless sound experience comparable to a wired one," commented Eric Palonen, senior product specialist, consumer electronics, Sennheiser USA. "These models contain the same features and functionality of their predecessors, and additionally, listeners will now be able to experience increased fidelity whether they are listening to music or making calls."

Consumers using computers without apt-X can still benefit from Sennheiser's use of high-quality Bluetooth® chipsets by pairing any of the new TRAVEL Series headsets with the new Sennheiser BTD 500 USB dongle to add Apt-X transmission to their computer-based music system.

The new MM 450-X and MM 550-X TRAVEL Series headsets also combine the first-class comfort, quality and convenience of a state-of-the-art Bluetooth headset with a luxury noise-canceling headphone. These headsets features Sennheiser's exclusive NoiseGard™ 2.0 active noise cancellation technology and TalkThrough technology enabling travelers to communicate with people nearby without removing the headset. Additionally, the MM 550-X utilizes SRS Labs’ SRS WOW HD™ technology for a more exciting listening experience at the touch of a button.

The MM 400-X, MM 450-X, MM 500-X and MM 550-X are available now at the street prices of $269.95, $449.95, $329.95 and $499.95 respectively.
