Plantronics' Discovery 665 headset with two-way DSP

Seems like every Bluetooth headset manufacturer is looking for a buzzword to describe their products' goodness in squashing ambient noise, but amazingly, Plantronics claims it's the very first to apply signal processing on both ends of the call in its Discovery 655-based "665." The DSP, called "AudioIQ," is said to reduce background noise by 7-8 decibels (roughly 50 percent) for folks on the far end of the call, while the wearer can expect improved "quality, clarity and volume level" as conditions vary. Look for the 9 gram headset to hit the streets next month for $150.
