Massdrop Releases Massdrop x HiFiMAN HE-350

In 2010, HiFiMAN released the HE-300, HE-500, and HE-6, a series of headphones that rivaled those from the world’s most established brands and redefined price-to-performance expectations in their respective categories. This product line solidified the still-young company’s status as one of the most respected names in the audiophile community.

Today, we’re proud to announce the Massdrop x HiFiMAN HE-350, a custom product based on the company’s entry-level HE-300, which was eventually discontinued despite being a clear favorite for many. This model has everything you loved about the original, plus a few awesome updates made in response to feedback and requests from the community.

What's New

The HE-350 uses entirely new dynamic drivers, different from those in the HE-300, resulting in a more neutral sound signature with less distortion and more detail. We've also improved the cable connectors and plug, and updated the frame to HiFiMAN’s latest (and much lighter) structure. We made the headband more comfortable for those long listening sessions, and changed the colorway from black and silver to a more understated black and gray.

Best of all, we’re able to offer the HE-350 at an even more accessible price point. How accessible? We’re talking $99.99 shipped to your door in the United States. Developed in collaboration with our friends at HiFiMAN, this will become the entry-level audiophile headphone recommendation.
