    • HiFiMAN HE-400i

      Rightfully a true master in the high-end headphone world, HiFiMAN is proud to present the newest member of their acclimated planar magnetic headphone range, HE-400i. HiFiMAN has taken all the essential features of the hailed HE-400 and improved upon them. With enhanced planar magnetic driver design the HE-400i offer a more transparent and spacious presentation. The lighter weight and re-designed comfortable earpads and headband add to the absolute audiophile listening experience.

      The HIFIMAN HE-400i are high quality, full size planar magnetic headphones designed for critical listening in the home or studio. Unlike dynamic drivers used in most headphones and speakers, planar drivers use thin flexible diaphragms with voice coils etched onto their surface rather than a voice coil attached to a cone.

      HiFiMAN HE-400i are lighter than the strapping HE-400 design and features a suspended headband connected on two sides by the band structure. This, along with its driver housing design makes the headphone much lighter and airy than the previous generation.

      Taking audio technologies to the next level - HE-400i.
