RASEN Bass™ (Reference Acoustic Spiral Enhanced Bass) is a patent-pending solution – precisely calculated and designed 3D printed structure – that creates low-end notes as realistic as a true subwoofer.
Meanwhile, SES™ (Space Expanse System) is Craft Ears' very own field-specific, 3D printed, horn-loaded tweeter tuned in a very particular bandwidth. Bringing to the field unique inventions to continue the development of the venerable balanced armature, Craft Six is the beginning, and the end, of your search for a TOTL IEM.
Headfonics praise the company for "ensuring the BA drivers are not overly pushed and peaky to deliver that natural and very balanced sounding tone", Twister6 checking off the "clarity, resolution, realism" requirements for a flagship. The Headphone List reserves mention for Craft Six's dynamic-like power, and Ear Fidelity, its speed and clinical approach.
Headfonia round out the accolades with a Recommended Buy award, recognition for Craft Six "getting the very most out of its drivers with a technically strong performance and a smooth musical tuning".
