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

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.

Acoustically Invisible Stealth Magnets

The advanced magnet design featured in the SUNDARA Closed-back 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.

Unlike the sound waves that are created by conventional magnets, the unique shape of stealth magnets enable soundwaves to pass through the magnet without generating interference.

Degradation of sound quality in a conventional planar magnetic headphone is caused by the magnets getting in the way of the sound wave.

The same happens in conventional electrostatic head-phones, where the degradation of sound quality is caused by the stator’s interference.

A conventional dynamic driver’ s frequency response can be altered due to distortions and vibrations across the diaphragm surface.

NEO Supernano Diaphragm

HIFIMAN 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 details but ultra-low distortion too. SUNDARA Closed-back offers performance levels and musical purity that exceed expectations, especially for such an affordable headphone.

Replacing Ear Pads

To remove the ear pads, locate the clips on the inside of the pad, and use two fingers to gently bend them in and slip them out. To install new pads, simply align the ear pad with the mounting ring, and gently bend the clips so they slot in their appropriate locations.

Care and Maintenance

The headphones benefit from break-in to achieve optimum performance. Usually, this takes up to 150 hours. Until then, there is nothing special you need to do other than enjoy your headphones.
Wipe the surfaces (ear pads, cups) with a microfiber cloth and store the headphone in a dry, cool, and safe place (away from dust, heat, humidity, sunlight, younger kids, and pets if possible).
To prolong the life of the headband, periodically wipe it with a clean, dry cloth.
Avoid exposure to extreme heat or cold.
Do not use any headphone while driving or operating machinery.
Do not use volatile substances, including alcohol, acetone, gasoline or dish detergent, to clean the headphone.
