Outfitted with large 50-millimeter dynamic drivers and HIFIMAN’s innovative Topology Diaphragms, the HE-R7DX delivers excellent isolation, impressive details, and open-back-level soundstaging. Tuned for transparency, it’s a workhorse tailor-made for home and pro studios, as well as higher-noise environments such as communal living areas and commutes. Plus, it features custom earpads to provide uncompromising comfort—no matter where you choose to listen. Upgrade your headphone experience with a new closed-back benchmark. Hear the difference with the Drop + HIFIMAN HE-R7DX.

To challenge and conquer in the closed-back space, we needed a design that blended the tried-and-true with the innovative. Working closely with HIFIMAN, we outfitted the HE-R7DX with large 50-millimeter drivers for midrange focus, high-end clarity, and low-end punch. To give these drivers a competitive edge, HIFIMAN founder and chemistry PhD Dr. Fang equipped them with the company’s new Topology Diaphragms. An extension of Dr. Fang’s graduate research on the varying structures of nanomaterials, the Topology Diaphragm features an innovative, uniquely-manipulatable nanoparticle coating on its surface. The coating has distinct geometric patterns, which can be varied (along with their thickness and chemical makeup) to precisely tailor sound wave formation. This allows for a level of sonic control never before seen in headphone drivers. Originally unveiled on HIFIMAN’s RE800 IEM, the Topology Diaphragm has been scaled up for seamless performance on the HE-R7DX.

Founded in New York City in 2007, HIFIMAN has always kept its ears close to the audiophile community. Case and point: Dr. Fang, company founder and head engineer. Dr. Fang started out as an active contributor on Head-Fi, regularly attending local meetups while pursuing his doctorate at Columbia. When he realized his PhD research could be relevant to his passion—the music-listening experience and the audiophile products that improve it—he started talking with forum members and meetup attendees about what they’d like to see in the next generation of headphones. With his first designs, HIFIMAN was born. In the few short years since its inception, HIFIMAN has released several highly regarded audio products, all while keeping close ties with the audiophile community. At Drop, we couldn’t imagine a better way of doing things.
