CSR Launches Advanced Bluetooth Headset Design for Just $5

(Top News, 5 Mar 2008)

CSR has launched BlueVox2 mono headset solution costing just $5; the world's lowest cost advanced Bluetooth headset. BlueVox2 features extremely low power consumption and zero cost noise reduction. Featuring AuriStream for superior voice quality, simultaneous connection of multiple devices and support for Bluetooth version 2.1+EDR, BlueVox2 also presents headset manufacturers with the opportunity to design the world's smallest Bluetooth headsets through an ultra small 4.5x5.5mm BGA package option.

The low eBOM of $5 includes the BlueVox2 QFN chip, together with all of the components necessary for a Bluetooth mono headset mounted on a four-layer printed circuit board. BlueVox2 is power efficient, permitting 15 hours talktime with a small 120mAh battery. The device also includes hardware-based noise reduction technology at no extra cost.

The design also raises voice quality to the standard of a landline phone by using CSR's AuriStream CODEC, which delivers an ITU-T mean opinion score (MOS) of up to 4.2 out of 5, even without the additional benefits of noise reduction.

BlueVox2 is the first ever ROM headset design to allow two or more Bluetooth devices to be connected to the same headset—making it possible to take calls from both a work and personal phone or a phone and a VoIP dongle—without impacting the power consumption. In addition, BlueVox2 supports Bluetooth v2.1+EDR, offering Secure Simple Pairing, which greatly simplifies the headset-to-phone pairing process while significantly increasing Bluetooth device security. With the enhanced inquiry scan Bluetooth v2.1 can also gather and present a greater range of information when searching for devices, including a list of services each device supports.
