Founded in 1999, the German manufacturer is now entering the open-back headphone market for the first time with the&nbsp;<strong>H715 Reference<\/strong>, marking an interesting new chapter for a company best known for its studio monitors and loudspeaker technology.<\/p>\n\n\n\n<p>Much of ADAM Audio&#8217;s reputation was built on its refinement of&nbsp;Air Motion Transformer (AMT) technology, originally developed by Oskar Heil in the 1960s. The company&#8217;s proprietary&nbsp;<a href=\"https:\/\/www.adam-audio.com\/technology\/x-art\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">X-ART<\/a> (eXtended Accelerating Ribbon Technology)helped establish its position in the professional studio monitor market, while its continued development of loudspeakers and subwoofers expanded its global reach. In 2019, ADAM Audio became part of the&nbsp;<a href=\"https:\/\/www.adam-audio.com\/en\/news\/industry\/adam-audio-focusrite\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Focusrite Group<\/a>, joining a growing family of professional audio brands.<\/p>\n\n\n\n<p>There is, however, an interesting family connection to the headphone business. <strong>Klaus Heinz<\/strong>, ADAM Audio&#8217;s co-founder and former head of research and development, departed the company in 2014 and subsequently established\u00a0<a href=\"https:\/\/hedd.audio\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">HEDD Audio (Heinz Electrodynamic Designs)<\/a>\u00a0in 2015 with his son,\u00a0<strong>Dr. Frederik Knop<\/strong>. HEDD has since earned considerable respect for its studio monitors and innovative headphones,\u00a0<a href=\"https:\/\/www.ecoustics.com\/tag\/hedd\/\">several of which we&#8217;ve covered on eCoustics<\/a>. With ADAM Audio now entering the headphone market, two Berlin companies with shared engineering roots find themselves competing for some of the same customers. Nothing like a little family history to make the German audio industry more interesting.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-related-reading\">Related Reading:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.ecoustics.com\/reviews\/audeze-mm-100\/\">Audeze MM-100 Open-Back Studio Headphones: Review<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.ecoustics.com\/reviews\/beyerdynamic-dt-1990-pro-mkii\/\">Beyerdynamic DT 1990 Pro MKII Open-Back Studio Headphones Review<\/a> <\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-adam-audio-h715-reference-headphones\">Adam Audio <strong>H715 Reference Headphones<\/strong><\/h2>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"476\" height=\"900\"  itemprop=\"image\" src=\"https:\/\/www.ecoustics.com\/wp-content\/uploads\/adam-audio-h715-reference-studio-headphones-side.jpg\" alt=\"adam-audio-h715-reference-studio-headphones-side\" class=\"wp-image-337250\"\/><\/figure><\/div>\n\n\n<h3 class=\"wp-block-heading\" id=\"h-the-drivers\">The Drivers<\/h3>\n\n\n\n<p>At the heart of the H715 are custom-designed 150-ohm <a href=\"https:\/\/www.adam-audio.com\/en\/technology\/titanium-plated-pen-drivers\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">titanium-plated PEN<\/a> (polyethylene naphthalate) drivers housed within a woven steel mesh enclosure.<\/p>\n\n\n\n<p>The drivers incorporate neodymium magnets, a precisely tuned suspension system, and a patent-pending ventilation design. Together, these elements are engineered to deliver extended bass response, smooth high-frequency reproduction, and accurate transient response, resulting in a neutral sonic presentation well-suited to professional mixing and mastering applications.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-built-nbsp-for-nbsp-long-nbsp-studio-nbsp-sessions\">Built&nbsp;for&nbsp;Long&nbsp;Studio&nbsp;Sessions<\/h3>\n\n\n\n<p>The H715 Reference combines durable metal components with a lightweight, ergonomic design intended for extended listening sessions. Key features include a breathable steel grille, dual-sided cable connectivity, magnetically detachable earpads, and premium memory foam cushioning designed to improve comfort without compromising durability. <\/p>\n\n\n\n<p>The headband uses spring steel to maintain consistent clamping pressure, while the rotating earcups conform to the listener\u2019s head and distribute pressure evenly around the ears. ADAM Audio has also incorporated a central cutout in the headband padding to reduce pressure on the sensitive crown of the head, a thoughtful detail for recording engineers and listeners who spend hours wearing headphones.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-bringing-studio-calibration-to-the-h715\">Bringing Studio Calibration to the H715<\/h3>\n\n\n\n<p>The H715 Reference also benefits from ADAM Audio&#8217;s collaboration with&nbsp;<a href=\"https:\/\/sonnox.com\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sonnox<\/a>, extending its capabilities beyond the headphones themselves. Originally introduced alongside the&nbsp;<a href=\"https:\/\/www.adam-audio.com\/en\/headphones\/h200\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">ADAM Audio H200 closed-back headphones<\/a>, the&nbsp;<a href=\"https:\/\/www.adam-audio.com\/en\/technology\/headphone-utility-daw-plugin\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Sonnox Headphone Utility Plug-In<\/a>&nbsp;now includes H715-specific calibration profiles and adjustable crossfeed functionality.<\/p>\n\n\n\n<p>These tools allow users to tailor the headphone response and introduce a more speaker-like listening presentation by blending information between the left and right channels. For recording engineers working primarily on headphones, the added flexibility can help create a more consistent monitoring environment when mixing and mastering.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"900\" height=\"900\"  itemprop=\"image\" src=\"https:\/\/www.ecoustics.com\/wp-content\/uploads\/adam-audio-h715-reference-studio-headphones-front.jpg\" alt=\"adam-audio-h715-reference-studio-headphones-front\" class=\"wp-image-337253\" srcset=\"https:\/\/www.ecoustics.com\/wp-content\/uploads\/adam-audio-h715-reference-studio-headphones-front.jpg 900w, https:\/\/www.ecoustics.com\/wp-content\/uploads\/adam-audio-h715-reference-studio-headphones-front-768x768.jpg 768w, https:\/\/www.ecoustics.com\/wp-content\/uploads\/adam-audio-h715-reference-studio-headphones-front-600x600.jpg 600w, https:\/\/www.ecoustics.com\/wp-content\/uploads\/adam-audio-h715-reference-studio-headphones-front-100x100.jpg 100w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-listenhub-system-wide-calibration-beyond-the-recording-studio\">ListenHub: System-Wide Calibration Beyond the Recording Studio<\/h2>\n\n\n\n<p>The H715 Reference also includes access to <a href=\"https:\/\/sonnox.com\/products\/listenhub\" target=\"_blank\" rel=\"noreferrer noopener sponsored nofollow\">Sonnox ListenHub<\/a>, an advanced audio analysis, comparison, and virtual monitoring platform designed to help recording engineers make more informed mixing decisions. Available as a standalone macOS application, ListenHub can host plug-ins such as the Sonnox Headphone Utility, extending the H715&#8217;s calibration capabilities beyond traditional digital audio workstation (DAW) environments.<\/p>\n\n\n\n<p>This allows H715 Reference users to apply headphone calibration across different audio sources without relying on a DAW. Whether evaluating reference tracks, checking mixes, or listening through other applications, the system-wide functionality provides greater consistency and flexibility throughout the monitoring process.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-hi-fi-listening-mode\">Hi-Fi Listening Mode<\/h2>\n\n\n\n<p>The H715 Reference isn&#8217;t limited to professional studio applications. For audiophiles, ADAM Audio includes a 3-meter cable terminated with a 4.4 mm Pentaconn connector, allowing the headphones to connect directly to compatible balanced headphone amplifiers and premium Hi-Fi components. The cable connects to both earcups, providing separate connections for the left and right channels.<\/p>\n\n\n\n<p>A dedicated <strong>Hi-Fi mode<\/strong> is activated using a recessed switch on the left earcup, which separates the shared ground connection between the two channels to enable true balanced operation. This configuration is designed to improve channel separation and reduce electrical interference when paired with a compatible differential headphone amplifier. The mode can be deactivated when returning to conventional studio equipment, giving the H715 Reference the flexibility to move between professional monitoring and home listening without requiring two different pairs of headphones.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"900\" height=\"716\"  itemprop=\"image\" src=\"https:\/\/www.ecoustics.com\/wp-content\/uploads\/adam-audio-h715-reference-studio-headphones-with-case.jpg\" alt=\"adam-audio-h715-reference-studio-headphones-with-case\" class=\"wp-image-337251\" srcset=\"https:\/\/www.ecoustics.com\/wp-content\/uploads\/adam-audio-h715-reference-studio-headphones-with-case.jpg 900w, https:\/\/www.ecoustics.com\/wp-content\/uploads\/adam-audio-h715-reference-studio-headphones-with-case-768x611.jpg 768w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-ready-to-pack-up-and-go\">Ready To Pack-Up and Go<\/h2>\n\n\n\n<p>The H715 Reference can fold flat for transport and comes with a premium hardshell travel case. The case features dedicated compartments for the 1.3-meter coiled studio cable, 3-meter Hi-Fi cable, and interchangeable soft-cloth and faux-leather earpads, which attach magnetically for easy replacement.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-fully-serviceable\">Fully Serviceable<\/h2>\n\n\n\n<p>All the parts of the H715 can be replaced as needed &#8211; This includes the earpad and headband components.

Both are wired headphones, but the H715&#8217;s combination of professional calibration software, system-wide monitoring tools, and dedicated balanced Hi-Fi connectivity gives it a distinctive position in a market where sound quality alone is rarely enough to stand out.<\/p>\n\n\n\n<p>The competition isn&#8217;t exactly asleep at the mixing console. <a href=\"https:\/\/www.ecoustics.com\/reviews\/sennheiser-hd-490-pro-plus\/\">Sennheiser&#8217;s HD 490 Pro Plus<\/a> ($499) and <a href=\"https:\/\/www.ecoustics.com\/reviews\/audeze-mm-100\/\">Audeze&#8217;s MM-100<\/a> ($399) are two open-back studio alternatives that cost less.
