Nyne NITRO is our newest and most lightweight on-the-go party speaker. It may be light, but the sound is mighty. The powerful 4.1 channel speaker system plays music in 360° omni-direction. The convenient Bluetooth connectivity reaches up to 100 ft. in range, and it also features aux-in and USB ports for playback, as well as a 1/4” microphone input for karaoke night! The built-in 4400mhA rechargeable battery allows you to take the party anywhere, dancing along with its LED color-changing illuminations. Connect two NITRO speakers together wirelessly with the TWS feature for an even better and louder surround-sound listening experience.
