Second-gen full-range AMT headphones
The HEDD HEDDphone Two is an open-back studio headphone using an Air Motion Transformer (AMT) as a full-range driver, covering 10Hz to 40kHz from a single transducer. As the second-generation HEDDphone, it brings three substantive changes over the original: a revised AMT with stronger magnetic flux and a post-processed diaphragm geometry that lowers distortion and tightens bass impact; a 25% reduction in weight to 550g via carbon-fibre and magnesium construction; and the new HEDDband headstrap, which allows independent adjustment of height, width, and clamping pressure. Two cables are supplied – unbalanced with a 6.3mm jack and balanced with a 4.4mm Pentaconn – along with adapters, a second set of earpads, and a semi-rigid carry case.

How the AMT moves air
A conventional dynamic driver pushes a flat diaphragm forward and back to displace air. The AMT instead uses a pleated, bellows-shaped diaphragm: the folds squeeze together and expand, forcing air out from between them at several times the speed of the diaphragm's own movement. The larger effective surface area means each fold travels only a short distance, helping to keep distortion low across the full audible band. HEDD's Variable Velocity Transformation tunes the fold geometry along the diaphragm so that low frequencies, midrange, and treble all behave linearly from a single driver, without a crossover or separate transducers. In the HEDDphone Two, a stronger magnet system drives the diaphragm with greater authority and the post-processed fold geometry reduces modal resonance – the audible result is tighter bass and lower distortion through the upper midrange, where the original is a hint less clear.

More monitors than headphones
Neutrality, accuracy, transparency, breadth – these are the qualities that define the HEDDphone Two. The unique VVT technology allows the electrodynamic Air Motion Transformers to cover the entire audible spectrum, although of course they do need to be driven at a decent level to fully reproduce contours and dynamics in the low end. An open-ear headphone, the HEDDphone Two is ideally suited for mixing and mastering duties, but also for audio tracking or the editing suite. This fully revised model is more comfortable to wear than the HEDDphone One, both because the weight has been reduced by around 200g, and because the headband is fully adjustable, in terms of height, pressure, width, and curvature.

About HEDD
The family-owned company HEDD Audio was founded in 2015 in Berlin, where it still manufactures its high-quality studio monitors, subwoofers, and hi-fi speakers, as well as headphones – or HEDDphones. The name HEDD stands for Heinz ElectroDynamic Design, after its founder Klaus Heinz (who also founded ADAM Audio); his son, who himself has a PhD in musicology, is now CEO. The company’s R&D work is based on their decades of experience, and its mission is to deliver outstandingly detailed sound and optimum signal quality. A whole host of renowned DJs and mastering engineers, including DJ Jazzy Jeff and Sascha "Busy" Bühren, swear by HEDD products for their day-to-day work.
Built for committed studio work
The HEDDphone Two is built for engineers who already know they want a full-range AMT in a headphone – and who have the amplifier and the listening environment to back it up. Carbon-fibre and magnesium construction brings the weight down to 550g, and the HEDDband distributes that weight across the head rather than concentrating it on the crown, so multi-hour mixing sessions don't end with neck fatigue. Two cables are supplied as standard – a 2.2m unbalanced cable with a 6.35mm jack and a 2.2m balanced cable with a 4.4mm Pentaconn termination – along with a 3.5mm adapter, a 4.4mm-to-XLR adapter, a spare set of earpads, and a hard travel case. For engineers who'd rather have the original's larger earcup and don't mind the weight, the HEDDphone One, a sibling rather than a predecessor, is the natural alternative.
