ADAM Audio has spent decades building monitors for treated rooms. The H715 Reference is its attempt to put that experience on your head: an open-back flagship that ADAM itself pitches as a genuine alternative to its full-range systems.
It sits well above the closed-back H200 in the range. 40 mm titanium-plated PEN drivers, 150 Ω, a quoted 9 Hz to 40 kHz response, a dedicated balanced Hi-Fi mode, and a software suite built with Sonnox. At Soundium it's €659, and it's open for pre-order now.
Key Features & Benefits
- Titanium-plated PEN drivers. Custom 40 mm diaphragms with neodymium magnets, tuned suspension and a patent-pending ventilation system. ADAM quotes 9 Hz to 40 kHz at -3 dB and under 0.05% THD at 100 dB SPL, so the low end you hear is the low end in the mix.
- A real Hi-Fi mode. Pop in the included metal pin and the H715 runs true balanced audio from differential amplifiers. One pair of headphones for the studio day and the listening evening.
- Software that does the room's job. The Headphone Utility Plug-In sits on your DAW's master or monitoring channel, and ListenHub by Sonnox adds system-wide calibration, metering, referencing and imaging tools.
- Built to be serviced. Replaceable ear pads and headband pad, detachable cables, cable entry on either side, lay-flat design and a hard carry case. Around 300 g without the cable.

Who It's For
- Mixing and mastering engineers who want a headphone reference they can trust next to their monitors.
- Producers who mix in rooms that aren't treated, or who travel and need the same picture everywhere.
- Listeners with a balanced headphone amp who want one pair for work and for Hi-Fi.
Who should look elsewhere: if you need isolation for tracking vocals or work in a noisy space, open-back is the wrong tool. The closed-back ADAM H200 is the better fit there, at a fraction of the price.

Final Thoughts
The H715 Reference isn't trying to be a cheap way into ADAM's sound. It's the company's top-end answer to a problem every engineer knows: the mix that sounds right on headphones and wrong everywhere else. Serious drivers, a proper balanced mode and calibration software in the box make it one of the most interesting studio headphone launches this autumn.
