The secret to the best-sounding experience possible? Two top-of-the-line DAC chips.
ES9018 is currently the most expensive DAC chip available. It took HIFIMAN's design team an entire year to refine this highly regarded DAC chip by adding an extra oscillator to further upgrade its performance. Their hard work paid off. The final result raises the bar and creates an all new reference.
Advanced Step Potentiometer
The patented step analog volume control is designed for precise control and accurate channel balance. It removes the carbon film that tends to wear out easily. The resistors in both channels of the step potentiometer can be paired to make sure they are 100% identical. No-gain control circuit delivers performance unmatched by the digital volume chip.
Balanced Output: Perfected Sound Experience
HM901s brings balanced, high quality music reproduction creating joy for your ears. Designed to be adaptive for both balanced and single-ended output, HM901s offers wider balanced output signals with even more powerful resistance to interference. The sound stage and the separation are largely improved.
DSD Support Enhanced
DSD (Direct Stream Digital) files can be enjoyed on your HM901s with high quality playback. HM901s decodes 24-bit 192 kHz high definition music files and offers upsampling to 24/192. Also supports DSD 2.8MHZ file.
The New TAICHI II UI
Experience state-of-the-art sound quality with time-tested reliability. Newly improved design replaces balance/normal switch with a pair of earphone jack holes, making it easier to use. Contributing to the ease of use is the new TAICHI II UI. Derived from the original HM901 volume control, TAICHI II UI is designed to achieve the most intuitive user interface possible.
Faster power on/off in only three seconds - first anywhere in the industry!
Dual Voltage
Unlike the single battery design dominant at other portable music players, the HM901s' exceptional performance comes from the dual-battery solution, delivering +/- 7.4 volts, 2,000mA. Effectively reducing power-supply noise allows you to enjoy more of the music.
Replaceable Amp Card Design
We dream of a world where one design fits all. That is why we choose to use open interface for headphone amplifiers to allow more compatible designs available and a chance for third-party designers to collaborate with HIFIMAN.
Replace CD Player with the Dock
- No need to keep your CD/SACD player anymore.
- No need to sacrifice the details of the music you listen to.
- No need to compromise with the hustle of changing discs.
- Make HM901s your personal media player, simply add the dock with remote control, And voila!
