"The HEDD Audio HEDDphone D1 is one of my favorite mid-tier open-back dynamic driver headphones I’ve run into this year. It’s an enjoyable headphone that hits a nice midpoint between being a good headphone for the analytical ear while simultaneously maintaining an enjoyable musical temperament."
HEDD Audio HEDDphone D1 Review — Headfonics
"HEDD’s first TPCD headphone effort is nothing short of a triumph. Eight years of TCPD research have resulted in one of the most natural, fatigue-free dynamic headphones on the market. It’s not flashy or “fun” in the traditional audiophile sense, but it’s musically complete."
HEDD Audio HEDDphone D1 Review - Headfonia
"With the HEDDphone D1, HEDD Audio scores a real coup. Sonically, the D1 sets standards – and that even across classes at a comparatively affordable price. In fact, I didn't expect how much "HEDDroom" is still possible technically and sonically with headphones."

"HEDD Audio has launched the D1 headphone, which is likely to cause a stir. With innovative driver material, it impresses with breathtaking performance that sets standards in its price range. Highly recommended!"
At its core is the world's first Thin-Ply-Carbon membrane (TPCD) – a breakthrough that redefines what dynamic headphones can achieve.
The D1 was developed from an idea eight years ago and has been continuously improved over the years. It is the result of four decades of HEDD's acoustic expertise and collaboration with Composite Sound from Sweden, specialists in advanced audio membranes.
The D1 is based on precision, purposefulness, and material integrity. It offers reference accuracy and balance, making it perfect for anyone serious about sound.
The D1 is the world's first headphone with a dynamic driver and a Thin-Ply-Carbon-Diaphragm membrane (TPCD). Developed together with Composite Sound (Sweden), it combines HEDD's 40 years of acoustic experience with cutting-edge material science. The result is studio-quality clarity, balanced sound, and fatigue-free comfort. The D1 is made in Germany and comes with a 5-year warranty.
Dynamic headphones have always required compromises: speed versus stability, weight versus comfort.
Based on four decades of studio experience, HEDD has redeveloped the core of the driver.
The result is a design that offers studio-quality precision for personal listening: detailed, balanced, and fatigue-free.
Weighing 350 g, the D1 combines an ultra-light diaphragm with a compact driver architecture, enabling hours of immersive and fatigue-free listening enjoyment.
All components were designed with stability, fit, and a natural sense of lightness in mind.
With an impedance of 32 Ω and a sensitivity of 100 dB, the D1 delivers consistent performance across all sources – from portable players to dedicated amplifiers – and easily adapts to high-end systems without losing control and balance.
Every HEDDphone® D1 is made in Germany and fully serviceable. This reflects HEDD's belief that high-quality headphones should be durable.
All components are designed for precision, durability, and reliability in daily use.
