Cost breakthrough: stereo wireless headphones for mass markets

BlueTunes ROM is a groundbreaking device that slashes the cost of building advanced Bluetooth stereo wireless headphones for music and audio applications. Integrating DSP and RISC processors, stereo CODEC, Bluetooth radio and battery charger - the ROM-based chip reduces the electronic bill of materials to the lowest in the market.

CSR's design provides a fast path to market for a highly-desirable accessory for mobile handsets and media players - opening up major growth opportunity for OEMs/ODMs. Application flexibility is also built in and the design supports:

• SBC decoding, and optionally MP3* for improved audio quality
• Configurable 5 band EQ to improve end-user experience
• Portable video/TV applications by eliminating 'lip-sync' problems when wirelessly listening to sound tracks - thanks to CSR's FastStream CODEC
• Seamless switching between wireless music playback and voice calls
• High-end echo and noise reduction, allowing users to be heard clearly in noisy environments (single mic or optionally dual mic implementations)
• Higher-quality Bluetooth headset connections via CSR's optional AuriStream CODEC
