Two flagship headphones can sit in the same high-end price bracket and share almost nothing else. Put a ZMF Atrium next to an Audeze LCD-5 and you’re looking at two answers to the same question. What should a headphone be at the top of the market?
One is milled from solid hardwood in a shop near Chicago. The other is a planar-magnetic design engineered in California and now owned by Sony. Both are excellent, and neither is trying to be the other.
Two origin stories
ZMF Headphones started on a dining-room table. Zach Mehrbach was finishing a film-directing master’s degree around 2011, modifying Fostex T50RP headphones by hand, when the side project became the thing. Today it’s a husband-and-wife operation, Zach and Bevin Mehrbach, hand-assembling headphones in Berwyn, Illinois, with the wood cups CNC-machined in Collinsville. Kiln-dried solid hardwood, not veneer. Each pair is individually tuned. That detail is more or less the whole personality of the company: a headphone with grain, milled from a material that isn’t identical piece to piece, finished by people whose names you can find.
Audeze came out of a Southern California garage in 2008, but the garage story undersells it. Founders Sankar Thiagasamudram and Alexander Rosson met an ex-NASA engineer working on an ultra-thin flexible-circuit material and adapted it into a headphone diaphragm. That’s the DNA, a material-science idea turned into a product line. Audeze builds its planar drivers in-house in California and sells across three markets: audiophile, professional studio, and gaming. In August 2023, Sony Interactive Entertainment acquired the company and said it would keep operating independently inside the PlayStation ecosystem.
So you have a family shop that grew out of woodworking and film on one side, and an engineering house that grew out of a diaphragm design and now answers, ultimately, to a console platform on the other. That gap shows up in everything downstream.
What they’re actually made of
ZMF’s catalog is mostly dynamic-driver. The Atrium is the open-back flagship, introduced in 2022 and built around a patent-pending Atrium Damping System. The Verite runs a beryllium-coated dynamic driver in open and closed forms. The Atticus and Aeolus use biodynamic drivers. The Auteur is the reference-tuned open-back that most people point newcomers toward. And the Caldera is ZMF’s first planar-magnetic headphone, which is the interesting wrinkle: ZMF stepping onto Audeze’s home turf, but doing it in a wood cup, by hand, in Illinois.
Audeze is planar-magnetic to the core, with electrostatics on the side. The LCD-5 is the open-back audiophile flagship. The LCD-X is the studio workhorse that mixing and mastering engineers actually use on the job. The CRBN is an electrostatic originally developed with MRI-compatible medical applications in mind, a reminder that the engineering sometimes runs ahead of the music. Then there’s Maxwell, the wireless planar gaming headset with 90mm drivers, widely praised as best-in-class sound for the money. That product doesn’t exist in ZMF’s world, and it’s a large part of why Sony wanted the company.
Materials tell the story cleanly. ZMF asks you to appreciate wood, weight, and the hand of a maker. Audeze asks you to appreciate the driver: the flexible-circuit diaphragm, the in-house manufacturing, the measurement bench.
The sound, in broad strokes
Some caveats first. Tuning varies by model, and ZMF in particular voices its wood-cupped dynamics across a real range. But the family resemblances hold.
ZMF’s dynamic-driver house sound tends toward body, warmth, and a physical low end. These are headphones that feel like an instrument in the room rather than a scalpel. There’s a texture to them, a slight romance, that suits acoustic music, jazz, anything you want to sink into. The Caldera brings planar speed and control into that same warm-leaning philosophy.
Audeze’s planars lean reference and resolving. The LCD line is prized for tuning you can trust and detail that holds up under scrutiny, which is exactly why the LCD-X ended up in studios. Fast, controlled, revealing. Less about romance, more about hearing what’s on the recording.
Warmth and body against resolution and control. It’s a crude axis, but it does a decent job of predicting which one a given listener will reach for.
What ownership signals
This is where it stops being about frequency response. Buy a ZMF and you’re buying into a small, independent, owner-run maker, the boutique end of the hobby, with the scarcity and personality that implies. Buy an Audeze in 2026 and you’re buying a product from a Sony subsidiary. That isn’t a knock. Sony’s scale could mean better warranty support, wider distribution, and steadier R&D. But the meaning of the object changes. One is a craft purchase; the other is a very good headphone from a very large company.
Who each one is for
Reach for ZMF if the object matters as much as the output, if you want hardwood, hand-assembly, individual tuning, and a warmer, more physical dynamic-driver sound. Start with the Auteur, move up to the Atrium, and try the Caldera if you want ZMF’s take on planar. It suits the listener who wants a headphone with a maker’s fingerprints on it.
Reach for Audeze if you want reference-grade planar resolution, studio pedigree, and a range that runs from the LCD-5 down to a wireless gaming headset. Start with the LCD-X if you work with audio, or the LCD-5 if you want the flagship. It suits the listener who trusts engineering and wants to hear the recording, not the headphone.
Neither choice is wrong. They’re different values at a similar price, and the real decision is less about which one measures better than about which philosophy you’d rather live with.
