Plantronics M3500 Bluetooth headset introduces Audio IQ and DSP
Posted on 9-Jan-2004 08:18. | Tags Filed under: News.

Plantronics announced the M3500, a new Bluetooth mobile headset with Audio IQ technology. The M3500 builds on the platform of Plantronics' M3000 Bluetooth headset (reviewed here), integrating Plantronics' proprietary Audio IQ technology with a built-in digital signal processor (DSP) for superior audio quality, particularly in noisy environments. The Audio IQ software enhances the functionality of the M3500 to deliver intelligent audio, resulting in exceptionally clear voice reception.

For the person wearing the M3500, Audio IQ automatically analyses the incoming voice signal and raises the softer portions of the signal without causing distortion, making it easier to clearly hear and understand the person on the other side of the call. For the person receiving a call from an M3500 user, background noise is dramatically reduced, so the voice comes through clear and clean.

According to InStat/MDR, Bluetooth-enabled devices represent a growing category of both business and consumer products, with a 74% five-year compounded annual growth rate based on chipset projections from 2002 to 2007. By the end of 2004, Strategy Analytics predicts the worldwide installed base of mobile phones with Bluetooth will reach 93 million units.

It provides up to 3.5 hours of talk time and up to 76 hours of standby time. The M3500 includes a user-replaceable battery, two earloops (medium and large), an AC adapter, as well as accessories previously only available separately: a lighter adapter for in-car charging and a sleek carrying pouch.

The M3500 works with any Bluetooth device that supports the headset or hands-free profile, including computers, personal digital assistants (PDAs), smartphones and automotive telematics. It should be available worldwide in early spring 2004, with a suggested price of US$169.95.
