Established in 2007, HFIMAN continues to grow and innovate within the world of audiophile-grade portable products. Ranging in scope form the world's first true audiophile digital audio player (DAP), the HM801, to an extensive series of headphones featuring planar magnetic drivers, HIFIMAN is continually at the forefront of portable audio design and ingenuity.

When it comes to dynamic drivers, which offer unique opportunities and challenges, HI Fl MAN once again focused on developing a groundbreaking design, relying on a multi-tiered approach that resulted in scaling up the company's acclaimed Topology driver technology to create the HE-Rl0D closed-back headphone.

The application of nano scale particles to the upscaled Topology Driver allowed HI Fl MAN to exert greater control over and removal of diaphragm distortions, resulting in significantly improved clarity compared to typical headphones with dynamic drivers. [Details]
