ADAM Audio launches the H715 Reference open-back at $699.99, with correction software
The monitor maker's open-back reference headphone uses 40 mm titanium-plated PEN drivers at 150 ohms, ships with Sonnox calibration software, and reaches buyers in December.
ADAM Audio has announced the H715 Reference, an open-back headphone at $699.99 / £569.99 / €669.99, with global availability in December 2026. It uses 40 mm titanium-plated PEN diaphragms with neodymium magnets, rated at 150 ohms, and weighs 0.3 kg without its cable. A Hi-Fi mode switch separates the common ground so the supplied 3 m cable, terminated in 4.4 mm Pentaconn, can run from a balanced amplifier output; a 1.3 m coiled studio cable is also in the box. The package adds the Headphone Utility plug-in and the ListenHub app, developed with Sonnox, for system-wide correction.
Correction software makes the measured response the product, because a plug-in is only as good as the measurement its target was built from and the unit-to-unit consistency that lets one profile fit every pair. Two figures would settle most of it: the raw response before correction, and how closely several samples match each other. The Hi-Fi mode is described as a connection change rather than a tuning, so its effect should appear in channel separation, not in the frequency response.
