BlueVox2 provides headset vendors with the opportunity to refresh their entry-level product ranges, with designs providing greatly improved headset performance and audio quality -  at less cost. The links provide more details.

* BlueCore6-Audio ROM is available in 4.5 x 5.5 mm BGA (world’s smallest headset IC), or 7 x 7 mm QFN package. The $5 eBOM is based on the QFN version.
