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.
Aliph's Bluetooth Jawbone headset sports military-grade noise cancellation
We've seen our fair share of Bluetooth headsets (with and without DSP), and we hold a soft spot in our heart for the hardcore, rugged devices out there that can withstand next to anything, but Aliph's Jawbone earpiece blends the best of both worlds into one fashionable piece of kit. While the firm already has a wired version on the market, this Bluetooth-enabled set rocks a silver or red color scheme, dual microphones, lightweight design, and a noise cancelling sensor that is literally military-grade. Crafted after conducting research for DARPA, the goal was "to create a mobile phone headset capable of erasing background noise," even in less-than-amicable (or safe) situations. Although there's no pricing or availability information just yet, the unit has already made its way on the Award Honorees list for CES 2007, and if you want to see this bad boy in action, be sure to continue on after the jump for a YouTube demonstration.[Via BlueTomorrow]
Bongiovi Acoustics unveils miracle DSP chip for car audio
If there were ever a time where we'd need to hear it before we believed it, this would be it. Tony Bongiovi, an audio engineer who's been around the block a time or two (read: he worked with Hendrix), has finally crafted the miracle chip he's been missing for decades. Dubbed the Digital Power Station (DPS, not to be confused with DSP), the microchip is described as a "very sophisticated equalizer," and while it was originally "the size of a refrigerator," he looked to Glenn Zelniker, a specialist in digital signal processing, to program a wee chip to do the same thing. The result is a dynamically programmed microchip based on an off-the-shelf DSP from Freescale Semiconductor, which is housed in special headunits (like JVC's KD-S100) and has more than "120 points of adjustment" to tune the tunes to fill each vehicle perfectly. Reportedly, the chip even turns factory speakers into high-fidelity drivers, as it calculates the dimensions of the vehicle and the abilities of the cones while outputting the audio. The JVC unit will cost "between $700 and $1,000 installed," since you'll have to schedule an appointment with your service department to get the correct software installed for your make and model, but we'd suggest a trial listen before you plunk down your one large.[Via PhysOrg]
Meizu M6 SP gets better for less yuan
When we eyed the Meizu M6 Mini Player earlier this year, it was almost love at first playlist -- it was slick, small, and inexpensive. So you can imagine our joy in informing you that the new Meizu M6 SP will be just like its predecessor, only better and cheaper. The SP model will bring a new Samsung chipset that purportedly offers "advanced DSP functionality" for 150-300 yuan ($19-$38) less than the old version. The M6 SP comes in 1GB, 2GB and 4GB sizes, and will cost between 700 yuan ($88) and 1,300 yuan ($164); hopefully, that'll translate into price cuts for the US markets as well. [Via DAP Review]
Plantronics intros Discovery 655 Bluetooth headset
Plantronics is feeling the ergonomic vibe as they introduced a new flagship Discovery headset at their Body and Form event in New York. The Discovery 655 is a form-focused Bluetooth headset with a distinctly different look than the 645 / 640 models. The design is intended to fit the "contours of your face" and shouldn't cause any ear fatigue weighing only 9 grams. Similar to other Discovery models, the 655 comes with a headset storage jacket -- which could be mistaken for an aluminum cigar case -- that performs double-duty as a charger (AAA powered), and a vibrating ringer to alert users of incoming calls. You also get a mini-USB adapter, which was notably absent on the Discovery 640, to charge from your PC or mobile phone's power supply. As in the 645, this unit includes DSP to block out unwanted noise (or certain managers' voices) and adjust the volume level based on your surroundings. Although there's really nothing groundbreaking about the 655 in terms of specifications, the change in style and lower price standout on an otherwise uninspiring offering -- you can give the Discovery 655 a listen when it drops in August for $150.
