CSR announced that Nokia's smallest ever Bluetooth mono headset, the Nokia Bluetooth Headset BH-800, contains CSR's BlueCore4-ROM silicon. The Nokia Bluetooth Headset BH-800, launched at CES 2006 and available from the second quarter of 2006, is Nokia's first Bluetooth wireless headset to feature Bluetooth v2.0 with Enhanced Data Rate (EDR).

The headset also benefits from the newly ratified HFP1.5 Bluetooth profile improving overall voice quality. Following a stylish and minimalist design, the Nokia Bluetooth Headset BH-800 weighs only 9g and has a standby time of up to 160 hours. The headset features three main buttons positioned at the back of the device to handle calls as well as support voice recognition capabilities. This enables the user to make and receive phone calls without the need for any further interaction with the mobile device.

The first Nokia headset to support Bluetooth v2.0+EDR, the Nokia Bluetooth Headset BH-800 employs CSR’s BlueCore4-ROM single chip radio and baseband IC. It can deliver data rates up to three-times faster than current v1.2 Bluetooth devices and lower power consumption. BlueCore4-ROM is backwards compatible with existing Bluetooth v1.1 and v1.2, meaning the Nokia Bluetooth Headset BH-800 can be used with a host of compatible Bluetooth devices.

The Nokia Bluetooth Headset BH-800 also implements the new HFP1.5 Bluetooth profile ratified by the Bluetooth Special Interest Group (SIG) in 2005. The new Bluetooth profile, designed for headsets and handsfree calling, enhances overall voice quality and connection reliability. The profile allows two voice packets to be sent at the same time, which means that there is a much lower chance of a packet being dropped compared with previous HFP Bluetooth specifications. HFP1.5 also enables the effective implementation of eSCO (enhanced Synchronous Connection Orientated) channels, originally introduced with v1.2 of the Bluetooth specification.
