Wireless and USB conference room speaker features a compact, portable design to provide professional-quality audio wherever you are. Full duplex technology allows you to speak and hear the other party at the same time for more dynamic conversations. Digital Sound Processing cancels ambient noise around you and suppresses echoes to ensure your voice is heard. Omnidirectional microphone captures audio from any direction to allow calls with multiple people. Its passive bass radiator produces a realistic, deep bass and rich sound so you can stream music when you're not on a call. Near Field Communications (NFC) chip lets you simply touch your NFC capable device to the speaker to connect automatically. Lithium Polymer battery provides more than seven hours of talk time on a single charge to keep your conversations going. Pair this portable speaker with your smartphone (iPhone or Android), tablet (iPad or other), PC, Mac and more. Non-Bluetooth devices can also connect using the 3.5mm jack.
