At the CSR Wireless Audio Training Seminar in Taipei today followed by Shenzhen on May 15, 2008, Phitek Systems Ltd, global leader in advanced noise cancellation technologies, announced that it has launched its Active Noise Rejection (ANR™) enabled Bluetooth stereo headset design.

To deliver premium audio and standard setting noise cancellation in a high performance Bluetooth stereo earphone, the new design leverages Phitek's new PHA-1 integrated ANR™ electronic and PHC-3 acoustic components, Phitek audio enhancement software products and the CSR BlueCore5-Multimedia.    

Being the latest in portable audio innovations, these Phitek ANR™ electronic and acoustic components complement the virtual surround sound and psychoacoustic bass enhancement software products announced when Phitek joined the CSR eXtension Partner Program in early 2007.

CEO of Phitek Systems, Mark Donaldson, says Phitek components are currently being used by the Company's key global customers to take leading positions in the emerging market for mobile premium audio. Donaldson comments: "Our Bluetooth ANR™ example design will enable OEMs and ODMs to deliver world class noise cancelling audio products much faster than ever before allowing greater efficiency and cost savings".

Phitek Product Manager (ANR™ Components), David Somppi, says Phitek has taken its IP and ANR™ know how and packaged it into the smallest possible form factor. Sommpi declares: "A designer now simply plugs the components together and obtains instant stereo ANR™ functionality - that's an unbeatable advantage in today's premium mobile audio market."

Somppi adds the fact that Phitek's feedback-based ANR™ offers exciting benefits which can be leveraged by mobile phone and Bluetooth headset OEMs. "Phitek's proprietary electro-acoustic design is optimized to deliver rich bass and extremely low Total Harmonic Distortion. ANR™ works all the way down to 20Hz to remove background noise that would otherwise degrade the listening experience. Outstanding audio reproduction and standard setting noise cancellation are now easily implemented in earphone designs."
