Classic Sennheiser sound, with a twist
The collaborative efforts of Massdrop's Community and Sennheiser brought about the HD 6XX - with all of the same benchmarking performance of the acclaimed HD 600 series family, plus a few updates for versatile everyday listening with laptops, smartphones, and DAPs. All at a value that is even easier to love.

Good news for fans of the HD 600 Series
In this Massdrop community-inspired revision, the driver structure and sound signature haven’t changed a bit. You’ll get the same smooth, effortless presentation, with a balanced midrange and natural-sounding bass.

Refreshed Aesthetic, Improved Utility
Crafted with the modern audiophile in mind, the HD 6XX supplements the clean, sophisticated aesthetic of the HD 600 Series with something more dramatic and unique to the HD 6XX: a deep midnight blue.

Unique form meets community-inspired function
The HD 6XX includes a detachable 6-foot/1.8m cable (compared to the original’s 10-foot cable) and a 3.5mm plug, which is more versatile for everyday laptop, phone, and DAP use than the standard 6.35mm plug; a 6.35mm cable adapter is also included.
