Message from the Founder

Thank you for your purchase of a HIFIMAN product. We take great pride in offering audio products that provide best-in-class performance and value.

Though it seems like only yesterday when, as a passionate audiophile, I started HIFIMAN, we just finished our first decade in business and eagerly look forward to an exciting future. The company continues to grow at a rapid pace, and the HIFlMAN brand is one of the most respected in the industry.

Even with our success, two things that never change are my love of music and my commitment to creating products that recreate the experience of hearing a live performance. I am joined by many others in the company who share my passion and in turn, we humbly share our passion with you.

Thank you again for your purchase. I hope you will find this guide a useful tool for learning about your product, ultimately helping you enjoy countless hours of pleasure.

Happy listening,

Outstanding Sound Quality

Compared to traditional dynamic headphones, planar magnetic technology offers a superior sounding experience in terms of overall quality, especially when it comes to the aural soundstage Dynamic headphones utilize conductors that vibrate in select areas of the diaphragm This results in a large percentage of the diaphragm not being directly driven by those conductors, resulting in somewhat diminished performance Planar magnetic headphones are fundamentally different in that their weight (conductors + diaphragm) is much lower than dynamic headphones The result is superior performance, especially in the upper frequencies, or treble.

fh: upper frequency bound ml: mass of diaphragm m2: mass of conductor traces

A smaller mass from either the diaphragm or conductor results in improved upper frequency response.

Planar headphones feature conductive layers distributed throughout the surface of diaphragm. The diaphragm is evenly driven by the magnetic force so that planar headphones produce significantly lower distortion when compared with conventional dynamic headphones

This lower distortion results in better overall reproduction of minute details. Positioning of instruments and other elements of imaging are demonstrably better, with a soundstage that is consistently wide and natural sounding

The Stealth Magnets

The advanced magnet design featured in the DEVA Pro is acoustically transparent, dramatically reducing wave diffraction turbulence that typically degrades the integrity of the sound waves. The result is reduced distortion, yielding a purer, more harmonious sound that is demonstrably better than previous designs.

HIFIMAN NEO “Super Nano Diaphragm”

HIIMAN devoted extensive time and resources to create a nano scale thickness diaphragm that allows for lightning fast response that not only produces stunning levels of detail but ultra-low distortion too. Making use of technologies originally developed for such revered models as the HIFIMAN Susvara, and borrowing the same driver shape, the DEVA Pro offers performance levels and musical purity that exceed expectations, especially for such an affordable headphone.
