Pro-quality conference room speaker offers a portable size. Pair this portable speaker with your smartphone (iPhone or Android), tablet, PC/Mac, or other A2DP Bluetooth device. Non-Bluetooth devices can also connect via the 3.5mm jack (using your own audio cable). The NFC (Near Field Communications) chip means you can touch your NFC-capable device to Conference Mate, and it will pair automatically instead of the standard Bluetooth method of pairing. Full-duplex design so you can speak and hear the other party at the same time. Design also features DSP for noise cancellation and echo suppression. Dual, high-quality, omnidirectional mic array allows the unit to capture everything you say. You can also use the speaker to stream full, rich-sounding music from your A2DP Bluetooth device. USB recharges the high-power density Lithium Polymer battery.
