HiFiMan HM-901U High Resolution Portable Music Player

The HM901U's all new CNC alloy casing combines sleekness and high durability. It prevents system crashes due to temperature issues and other disturbances. This results in largely improved system reliability.

Sound Quality Driven Technology

Secret to the Best-Sounding Experience? ES9018 DAC The HM901U utilizes a pair of the new top-of-the-line DAC chips from ESS Technology. The ES9018 is one of, if not the most impressive, high performing DAC chips available.
The result is a warm and neutral sound, emphasizing phenomenal midrange reproduction, largely improving upon the dry, cold and analytical nature commonly found with other implementations with only a single ES9018 chip. As such, the HM901U raises the bar and sets a new standard for high-resolution portable audio players.
