The Jabra BT800 is one of the most advanced Bluetooth headsets available today, offering a backlit display, call vibrate feature, variable ringtones, a jog wheel for volume control during calls and menu scrolling in standby mode. Most significantly, the Jabra BT800 employs the digital signal processing See DSP. Digital Signal Processing - (DSP) Computer manipulation of analog signals (commonly sound or image) which have been converted to digital form (sampled). (DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive ) technology in BlueCore3-MM for improved sound quality and for noise reduction. The Jabra BT800 is currently shipping in Europe, the Middle East and Africa Europe, the Middle East and Africa, usually abbreviated to EMEA, is a regional designation used for government, marketing and business purposes. It is particularly common amongst North American based companies, who often divide their international operations into the at 149 Euros and is expected to roll out to the US and Asia Pacific markets in the coming months. CSR's BlueCore3-MM complies with both the v1.1 and v1.2 Bluetooth standards allowing the Jabra BT800 to connect to any Bluetooth-enabled mobile phone on the market. BlueCore3-MM offers: eSCO (enhanced Synchronous Connection Oriented) voice channels to ensure that no part of the voice transmission is lost due to corruption of data packets; and adaptive frequency hopping (AFH AFH Adaptive Frequency Hopping AFH Away From Home AFH Army Family Housing AFH Air Force Handbook AFH Atlantic Fish Health (Charlottetown, PEI, Canada) AFH Administration, Finance, and Human Resources ) which further minimises potential interference from other radio devices. The on-chip DSP, which is integrated into the CSR Bluetooth chipset, has given the Jabra engineers the opportunity to make great advancements in the reduction of background noise .The Jabra BT800 will change volume settings according to the surrounding conditions where the call is made. Therefore, when talking in a noisy street or on a train, the headset will automatically adjust the volume of the call to counteract any ambient noise. "Jabra and CSR have worked together on a number of projects bringing feature-rich Bluetooth headsets to accommodate the rapidly evolving mobile phone market," commented Niels-Henrik Valentin Knudsen, senior product manager, Jabra. "CSR's BlueCore technology helps us to continually push the boundaries of Bluetooth headset design and offer our customers premium quality products with innovative design." Luke D'Arcy, Product Manager, CSR added, "Sound quality and battery consumption remain the most important features of a Bluetooth headset. The integrated DSP of BlueCore3-MM combined with the standard features of v1.2 Bluetooth to ensure optimum sound quality without signal degradation, and very low power consumption. The Jabra BT800 offers an attractive package of quality and features to satisfy the changing design and functionality demands placed on the next generation of Bluetooth headsets."
