ADAM Audio H715 Reference Studio Headphones

ADAM Audio H715 Reference — Flagship Open-Back Studio Headphones

The ADAM Audio H715 Reference is the brand's flagship open-back headphone, designed to bring the experience of a full-range monitor system playing back in a treated room directly to the ears of audio professionals and discerning listeners. Built around custom 40 mm titanium-plated PEN drivers and a patent-pending ventilation system, this model targets mixing, mastering and Hi-Fi listening where transparency and low distortion matter most. The H715 Reference is the right choice for engineers, producers and serious music enthusiasts who need reference-grade accuracy without sacrificing long-session comfort.

Standout Features

What sets this model apart is titanium-plated PEN drivers housed in a woven steel mesh enclosure with a patent-pending ventilation design. A dedicated Hi-Fi Mode — activated via a small switch on the headphone using the included metal pin — splits the common ground so the bundled 3 m double-entry Pentaconn cable can deliver true balanced audio from a differential amplifier. The headphones ship with the Sonnox-built Headphone Utility Plugin and the ListenHub application for system-wide calibration, adjustable crossfeed, metering and reference-track comparison.

Driver Technology — Reference-Grade Accuracy

The driver assembly is the heart of any reference headphone, and ADAM Audio engineered this one for exceptionally low distortion and a snappy transient response. Neodymium magnets with meticulously tuned suspensions work with the patent-pending ventilation system to deliver deep, well-controlled bass and high sensitivity without colouration.

• Transducer: 40 mm titanium-plated PEN diaphragm — custom-designed for accuracy and emotional connection to the source.
• Magnet: Neodymium with tuned suspension for high efficiency and controlled excursion.
• Impedance: 150 Ohm — pairs cleanly with dedicated headphone amplifiers and studio interfaces.
• Sensitivity: 102 dB SPL @ 1 Vrms / 94 dB SPL @ 1 mW — ample output from a wide range of sources.

Acoustic Performance — Full-Range Headroom

An open-back headphone lives or dies by its frequency extension and distortion behaviour at realistic listening levels. The H715 Reference is designed as an alternative to full-range speaker systems, with enough headroom for the loudest passages in modern productions.

• Frequency Response: 9 Hz – 40 kHz (-3 dB) — extends well beyond the audible band for accurate transient capture.
• Max SPL: 113 dB @ 1 kHz, 0.05% THD — headroom for loud passages.
• THD: <0.05% @ 1 kHz, 100 dB SPL — clean reproduction at typical monitoring levels.

Comfort, Build and Connectivity

Long mixing sessions demand a headphone that disappears on the head. The H715 Reference uses a spring-steel headband with a central cutout to relieve crown pressure, memory foam earpads, and rotatable earcups that adapt to the shape of the head. The earcups fold flat and the modular construction — with replaceable earpads and headband pad — is built to last.

• Weight (excl. cable): 0.3 kg — lightweight for marathon-length sessions.
• Cable Entry: Left or right side, double-entry with balanced cable — flexible routing for studio or desktop use.
• Source Connectivity: 3.5 mm TRS with 6.3 mm adapter, or 4.4 mm Pentaconn for Hi-Fi Mode — works with interfaces, amps and balanced sources.
• Package Contents: 3 m straight cable, 1.3–3 m spiral cable, hard carry case, magnetic soft cloth and faux leather earpads, metal Hi-Fi pin.

Who Is It For

The ADAM Audio H715 Reference is the right choice for mixing and mastering engineers, post-production specialists and critical listeners who need a transparent reference that translates confidently between headphones and loudspeakers. It suits producers working long sessions who value the lightweight 0.3 kg build, memory foam earpads and replaceable modular components. Audiophiles with balanced headphone amplifiers will appreciate the dedicated Hi-Fi Mode and Pentaconn cable, while users of any DAW benefit from the included Sonnox Headphone Utility Plugin and ListenHub application for calibration, crossfeed and reference-track workflows.

Brand & Product Story
