Founded in 2005 by Dr. Fang Bian, HiFiMAN Electronics designs and manufacturers audiophile quality products including headphones, amplifiers, and portable audio players. HIFIMAN is renowned for their full-size, planar magnetic headphones from the HE400s to the HE1000 v2. The company uses proprietary materials and techniques that allow music lovers to experience music as never before with lifelike clarity and detail.

The HIFIMAN EF100 is a powerful hybrid headphone amplifier and integrated amplifier. Housed in its compact chassis lie three independent amplifier sections: a vacuum tube input stage works as a shared preamp, a Class AB headphone amplifier, and a Class T speaker power amplifier. In addition, the EF100 can also serve as a hybrid power amplifier to drive speakers of moderate to high efficiency. Driven by front stage’s vacuum tubes, EF100 combines the warmth vacuum tubes are known for with the high efficiency of a digital amplifier. It is the best of both worlds.


In addition to designing state-of-the-art headphones, it’s only natural to design portable audio players to take advantage of high resolution music. Offering a variety of different models, each with their features to serve the avid listener’s needs, there is a player to meet every budget. Superior DACs and quality amplification make these player a must for anyone who wants to reach a higher level of fidelity.
