The Polycom VoiceStation 500 is a small Bluetooth-enabled conference phone ideally suited for desktops, offices, and other small rooms. With a microphone range of up to seven feet, the VoiceStation 500 is perfect for small conferences with three to four participants. Plus its compact industrial design fits well on a desk or small table, making it a great solution for offices. With the VoiceStation 500, you can enjoy Polycom's legendary voice quality at an affordable price. Use your Bluetooth-enabled mobile phone to connect wirelessly to the VoiceStation 500 for hands-free voice conferencing, even from locations without an analog phone line. It can also connect to a Bluetooth-enabled computer for high-quality hands-free conferencing over the Internet. If your mobile phone or computer is not Bluetooth-enabled, simply use the integrated 2.5mm applications port for wired connections. Polycom Acoustic Clarity technology delivers exceptional performance and voice quality, making your conference calls clearer and more productive. Industry-leading full duplex technology provides natural, simultaneous two-way conversation without clipping or drop-outs that are common in traditional speakerphones. Users can speak in a normal voice and be heard clearly up to 7 feet away - making every call a more productive call. Dynamic Noise Reduction (DNR) actively removes background noise such as projectors and ventilation systems, while 360-degree microphone coverage with intelligent mixing highlights the person speaking, not the distracting ambient sounds, for crystal clear conferencing. It also features technology that resists interference from mobile phones and other wireless devices, delivering clear communications with no distractions. Convenient controls for Bluetooth, volume adjustment, mute, redial, flash and hold are located on an intuitive, easy-to-use keypad. When dialing over regular phone lines, a handset phone can be plugged in for private calls, or simply switch back to the VoiceStation 500 for hands-free conversations.
