Massdrop x Sennheiser HD 6XX Headphones - Refurb

We’ve been working hard to make sure we get the color of the headphones to match exactly what we had in mind. It’s taken multiple rounds of prototypes, but we think we’re finally there. And it’s been all hands on deck: in order to get the most recent sample delivered on time, chief engineer Axel Grell hand painted the headphones himself and oven cured them in his kitchen! With the new shorter cable (6 feet compared to the original’s 10 feet) and the more versatile ⅛-inch plug already implemented, we’re getting closer and closer to unveiling this product to the world.

When identifying partners to collaborate with, we’re always looking for companies who can deliver based on the needs of our community. Sennheiser is that to a T. Audiophiles have long considered the HD 650 to be the best open-back headphone under $1,000, but we’ve also heard feedback that a few small changes could make it even better. So when we met up with the Sennheiser team at CES in Las Vegas, we knew we wanted to pitch an idea for a custom revision of the HD 650. Following a formal presentation, the team was inspired by our ability to gather the opinions and sentiments of audiophiles in a way they hadn’t seen done before. Now, the real work begins: we’re excited to announce that our two companies are teaming up to bring this product to life!
