Noise-cancelling microphones
Multipoint (.Audio 920)
(.Audio 310, .Audio 325, .Audio 345, .Audio 625 USB, .Audio 645 USB, .Audio 650 USB, .Audio 355, .Audio 470 USB, .Audio 400 DSP, .Audio 480 USB, .Audio 920)
Most wireless devices use point-to-point, which means they can only be connected to one device at a time – for example a mobile phone and a Bluetooth headset might be connected through point-to-point. Or a PDA device might be paired with a computer. When a headset has Multipoint capability it can receive information from more than one device at the same time.
Plantronics noise-cancelling microphones reduce the background noise and so enhance the accuracy of the sounds being transmitted. They are ideal for noisy environments. WindSmart (.Audio 440, .Audio 480 USB) Plantronics patent-pending WindSmart technology uses a specially designed material over the microphone to diffuse wind noise, so that even in windy environments – such as the car or the street – users can enjoy crisp, clear conversations.
QuickAdjust (. Audio 310, .Audio 625 USB, .Audio 650 USB .Audio 470 USB, .Audio 400 DSP)
Enables ideal microphone boom placement.
Other technology Bluetooth® (.Audio 920) Bluetooth wireless technology provides a way for devices to communicate with each other using short-range radio frequency instead of wires. Any two Bluetooth devices can communicate as long as they both have Bluetooth turned on, they are within range, and they have been paired – a quick “handshake” that connects the two devices. Bluetooth range is up to 10m. Obstructions, such as walls or other electronic devices, can cause interference or shorten the effective range. For optimal performance, place your headset and phone on the same side of your body.
Digital Signal Processing (DSP technology) (.Audio 400 DSP) Digital Signal Processing is a technology which delivers up to 35% reduction in background noise, whilst maintaining crisp, clear voice transmission. If you are planning to use your .Audio headset for chatting over the Internet, or for games which rely on voice recognition, it is well worth looking for a DSP model – especially so, if you live in a lively household where there is a lot of background noise.
