HEDD

HEDD is a German company founded in 2015 by Physicist Klaus Heinz and his son, Mastering Engineer / Musicologist Dr. Frederik Knop. The HEDD team consists of musicians and loudspeaker nerds, electrical engineers, graphic designers, and admin pros, all of whom are fully committed to the creation of this new brand.

HEDD is especially known for the production of high-end loudspeakers that have become established constants in diverse fields: from music production processes in professional recording and mastering studios to radio broadcasting, installation and finally home HiFi.

Heinz’ loudspeaker designs have always stayed true to the same ideal of sonic excellence: they have, above all, always aimed to produce complete accuracy and outstanding signal fidelity while being less concerned with tinging recording audio material with pleasing tonal colors. It comes, therefore, as no surprise that the product development department at HEDD | Heinz Electrodynamic Designs is fully committed to the idea of creating versatile and surgically precise studio monitors.

These brand-new studio monitors take another technological step in the development of the Air Motion Transformer. Years ago, Heinz revolutionized the professional world of audio production by introducing his first Air Motion Transformer. Today, AMT systems are used wherever an extremely precise and vivid reproduction of high frequency material is called for.

With all their AMT speaker experience, HEDD found it was time to explore the headphone market with a full range AMT driver. How could they not with the HEDD company name like that, is was meant to be. Right? This resulted in the HEDDphone, and that’s what we’re looking at today. The HEDDphone’s product page can be found here: https://www.hedd.audio/en/heddphone/.

The HEDDphone was officially announced about a year ago in May, right before the High End Munich show. I had seen and listened to an earlier HEDDphone version before but I at this show extensively got to listen to it. As the report said, it was a refreshing experience.

Aiming at both, the audiophile and professional markets, the HEDDphone – according to HEDD – brings the enormous dynamic capabilities and the superior sonic resolution of the AMT principle to the world of top-end headphones. It excels where it really matters: in accurate, untamed, and touching music reproduction.

HEDD – AMT

On the HEDD website we can find this info:

The Air Motion Transformer (AMT) is an electrodynamic transducer that allows to move air significantly faster than common voice coil, magnetostatic (planar) or electrostatic systems. Their traditional piston-like movement is overcome by a folded diaphragm that squeezes out air four times faster: A breakthrough for capturing more details in any audio recording. In order to reproduce the complete audible frequency band (and beyond), HEDDphone® introduces VVT® technology (pat. Pending), a new variable diaphragm geometry that replaces the fixed geometric structure of conventional AMT tweeters.

More on AMT by HEDD can be found here: https://www.hedd.audio/en/hedd-amt/ .

If you want to read up on the AMT technology, you can also do so on Wikipedia: https://en.wikipedia.org/wiki/Air_Motion_Transformer

It’s not the first time AMT drivers are being used in the ear- and headphone world, but the HEDDphone just might be the first full range AMT driven headphone.

    That is an excellent headphone and plays far, far above it’s price range.

    Too bad you, Lieven, didn’t focus as much and put more time describing the sound characteristics of this headphone.
    The heddphone has many unique sound characteristic, which in some ways sound different and fairly unique when compared to dynamic or planar drivers, which you could write about.
    There are some things about the heddphone which sound close to electrostatics from stax.
    That’s why I find it is a real shame you didn’t do a comparison between other headphones.

    It is an full range AMT driver, in a headphone – the first of it’s kind.

    Summaring, for me, this review is a big let down. 250 words written about bass, mids and treble. Out of these 250 words, a big part about the comparison between single ended and xlr output.
    You didn’t put as much time and effort in this review. Even the Hifiman Deva has more pages. Other headpones reviews from you are up to 6 pages.

    If you could and want, I would be happy if you ask for another review sample and rewrite it 😉

      There are 1410 words on sound. There are no direct comparisons as it to me makes no use to compare different technologies to each other
      If you really think no time or effort went in this review, you have no clue what you’re talking about, sorry.
      Summarizing, for me, your comment is also a big let down.

        You’ve already made comparisons in written reviews with other transducer technologies.

        “If you really think no time or effort went in this review …” – assumption, haven’t said that.

        Well can’t be helped; could be a far more comprehensively review ¯\_(ツ)_/¯
        Still, thanks and bye.

    How do you feel this would pair up with a Burson Conductor 3R? No balanced mode, but 7.5wpc out of single ended on tap. Looking for a good set of open cans focusing on SQ when I’m not needing to use my closed back Elegias due to other people in the area.
