Performance is PLEASURE

The GT is to the TWO, what a Gran Turismo is to a race car: more comfortable and certainly more forgiving. Whilst HEDDphone TWO was designed to be a cutting-edge engine to deliver fast and exceptional results for audio engineers and producers, the GT adopts the analytical clarity of the TWO, adding a warmer sonic signature and premium comfort experience. Every element of this high-performing product will enhance your ride.

The details you can HEAR

Like its professional counterpart, HEDDphone® TWO GT uses a robust, yet ultralight multi-layered Kapton diaphragm that is over three times larger than traditional dynamic, planar or electrostatic driver designs. The new HEDD Air Motion Transformer utilises the latest Variable Velocity Transform technology and produces the lowest ever distortion levels in AMTs across the audio spectrum, from 10 Hz to 40 kHz. Therefore the driver allows for more accurate dynamics and an effortless soundstage.
HEDD has combined substantial feedback from the passionate Head-Fi community with our unwavering dedication to improve. The new air-compliance tuning system creates impactful bass, alongside a warmer mid-range and sparkling top end to deliver the emotion within the music.
So, meet HEDDs Grandest Tuning to date.

To give our customers a choice between different comfort experiences without taking them away from the music, the new ear pads are finished in either velour or sheep leather. The improved cable quality adds to the overall luxurious experience.
