One of Our All-Time Best Sellers

If you know audio gear, you know the Sennheiser HD 650. The company’s flagship from 2003 to 2009, this open-back headphone has shown serious staying power. Praised for its richly detailed, effortlessly enjoyable sound, it remains one of the most talked-about products on Head-Fi today—and is still widely considered among the best headphones under $1,000. So when we teamed up with Sennheiser on its first-ever community-driven design partnership, the HD 650 was a natural place to start. A new revision of the popular all-rounder, the Massdrop x Sennheiser HD 6XX has that same great sound plus a few updates, and a price that makes it even easier to love. More than 30,000 members have picked it up to date. 

Note: This drop is limited to 10,000 units. Shipping is free to US members and $15 per unit internationally. Each member can purchase up to five (5) HD 6XXs. All units will be serialized.

Refreshed Aesthetic, Improved Utility

Crafted with the modern audiophile in mind, the HD 6XX replaces the HD 650’s gray colorway with something darker and more dramatic: a deep midnight blue. The silver nameplates have been swapped for black plates with contrasting silver text—and the Massdrop logo is silk-screened on the inside of the headband, just above the right cup, with the serial number located just above the left cup. Based on feedback from the community, this iteration has also been updated with a detachable 6-foot cable (compared to the original’s 10-foot cable) and a ⅛-inch plug, which is more versatile for everyday laptop, phone, and DAP use than the standard ¼-inch plug. Of course, the HD 6XX comes with a ¼-inch adapter for those who want it.

Classic Sennheiser Sound

Good news for fans of the HD 650: In this revision, the driver structure and sound signature haven’t changed a bit. You’ll get the same smooth, laid-back presentation, with a balanced midrange and natural-sounding bass. The HD 650 is considered more refined and better damped than its predecessor, the HD 600, with less energy in the upper midrange (which some listeners may find less fatiguing) and an overall balance that’s a bit warmer and bassier. Its neutral response provides a pleasant listening experience with any musical genre from a range of sources. Plus, it responds well to improved sources and amplification, and headphone amplifiers of any output impedance could potentially make a good match.

Final Thoughts

Because the HD 6XX’s open-back design won’t isolate you from outside noise or prevent sound from being heard by those nearby, it may be best-suited for quieter home and office environments. Like all headphones in Sennheiser’s HD 600 line, this new model can be disassembled by hand to its component parts, all of which can be easily replaced. Many of its parts are interchangeable with others in the series, and owners of the HD 6XX can benefit from the rich aftermarket and brain trust of modifications and gear matching—along with excellent long-term support from Sennheiser itself.
