INCISOR DIFFUSION TECHNOLOGY - Speakers. There's loads of them?? right? What can Cisor offer that no other can? Cisor sets itself apart from the rest by producing acoustics unique to each environment and surface. Each surface has different sound qualities to the next?? meaning there's no limit to the fun you can have experimenting and finding out which sound does it for you. It gets better - the bigger the surface?? the bigger the sound</br>KEY FEATURES - Playtime of up to 6 hours - Frequency range: 40hz - 20khz - Output: 10 watts - Bluetooth 4.0 - USB-C Charging - 3.5mm AUX IN - Connect 2 Cisors for wireless stereo - Separate metal suction mount can be used to attach it to many other surfaces</br>SOUND RANGE - Incisor Diffusion Technology has removed the need for a cone. It does this by using the surface to act as a "e": the surface diffuses the sound. This means the Cisor is able to provide a full audible frequency range down to as low as 30hz giving seriously deep bass and as high as 15khz. Different surfaces (or substrates) have different resonating properties?? so audio will sound slightly different depending upon the surface you place it on</br>EASY OPERATION - There is no buttons to worry about on the Cisor?? just a simple "ist" is all you need to get up and going. Twist it to bluetooth and connect a mobile device or connect it to another Cisor for wireless stereo sound! Twist to the Line-In side and plug in any other device</br>SPECIFICATIONS - Size: 2.7in x 2.3in - Weight: 11.3oz - Material: Anodized Aluminum?? Silicon?? ABS - Connectivity: Bluetooth 4.0??
