Most speakers are unidirectional, meaning the best sound is only directly in front of the device. Because the audio Cube uses omnidirectional speakers, the sound penetrates air space, without any dead spots. We created a 360 audio experience, where the sound interacts with the room. The AudioCube has incredible bass, especially for its sixe. This is further amplified by a vibrating plane, which also doubles as an on/off switch. There is also an intergrated LED so you can easily identify if the product is on. The AudioCube features clearly indicated buttons, where you can access all basic controls (pause, play, volume, next/previous song and scan for pairing) with a single touch and all controls have clear audio feedback. You can also control the AudioCube remotely from a distance using Bluetooth connectivity. A 360 degree directional sound that fills the room with great base. 4 speakers.
