The Brainwavz B400 uses a 4 Driver system, with each driver focused on its own specific range of the sound spectrum, resulting in a true audiophile grade sound. To achieve a truly ergonomic housing, we have used the latest in 3D printing technology. Each B400 is handcrafted in house by Brainwavz from components produced in the USA and Europe. Detachable MMCX cables The Brainwavz B400 use the industry standard MMCX cables. Detachable cables extend product life span, allow for additional features and creates a truly custom product experience. Balanced armature inside The B400 plays host to some of the finest drivers around. But this is only half the story, our unique 3D modelling and printing systems have enabled us to constantly design, test and hone the B400. 3D modelling and printing means we can innovate faster and experiment more, enabling us to create a unique system that lets the the Balanced Armatures perform above and beyond expectations. 3D printed Brainwavz B400 are unique in many ways, but one standout feature is how they are made. The main shells are printed using state-of-the-art liquid Resin 3D printers, enabling a shape not possible by normal manufacturing methods. Visit the Brainwavz Audio website.
