All-New Black & Gold Color Scheme:- Whizzer Kylin HE01 is a stunning pair with a unique combination of rose gold and white colors. The pair was designed by J.IDEA+ in collaboration with Whizzer. The latest HE01B takes the look of the HE01 ahead with a beautiful combination of shiny black and rich rose-gold colors. Whizzer finalized the Black and Rose gold scheme after trying multiple options, to present the user with a unique and rich final look. 4th-Generation Bright Series Dynamic Driver Delivering Quality Sound:- We all loved how beautiful, energetic sound the OG HE01 produced. The latest HE01B is equipped with the same trusted 10.2mm 4th gen bright series custom dynamic driver unit with a dual rear cavity design. It features a PU+PEEK composite diaphragm with a powerful 1.2T magnetic flux delivering exceptional sound performance with great clarity. HE01B also has a patented HDSS acoustic filter that allows for fine and precise adjustment on the front and rear cavities. High-Quality Upgraded Stock Cable:- While the HE01 and HE01B are almost identical in features, one of the main differences with the latest HE01B is the included high-purity cable. HE01B comes packed with a 4-strand 5N silver-plated oxygen-free copper cable. Each wire used here for this cable has an ultra-thin diameter of up to 0.05mm mechanically braided into a four-strand structure. The connectors have the same anodized CNC machined finish as the cavities.
