For mixing and mastering, the Amazon Renewed beyerdynamic DT 990 is my pick among these open back headphones for mixing and mastering, thanks to its 80-ohm design, replaceable ear pads, and long studio cable.
open back headphones for mixing and mastering at a Glance
• Amazon Renewed beyerdynamic DT 990 — best for a straightforward home or studio setup; pick this if you want an 80-ohm wired model with soft, replaceable ear pads and a 3-meter cable.
• Monoprice Monolith M1070 — best for exploring spacious planar sound; pick this if you want a 106mm planar driver and both lambskin and velour ear pads.
• Focal Clear MG — best for a premium-feeling listening setup; pick this if you value its magnesium driver design, perforated microfibre pads, and aluminum yoke.
• Austrian Audio Hi-X65 — best for a mixing-focused portable setup; pick this if you want a foldable open-back design, 25-ohm impedance, and a carrying case.
The DT 990 is an over-ear, open-back wired headphone intended for studio and critical listening. This is the Renewed version of the beyerdynamic DT 990 PRO, with an 80-ohm impedance and a 3-meter straight cable. Its open construction is meant to provide a spacious presentation, while its stated focus on spatial detail can help when judging placement and separation in a mix.
The 80-ohm specification makes it a plausible fit for a setup that includes studio equipment as well as home listening gear. It is still a wired headphone, so you will need a compatible output and a place to manage the long cable. The included threaded quarter-inch adapter also gives you a way to connect to a larger headphone jack.
For extended sessions, the circumaural ear pads are soft and replaceable, and the design is described as lightweight. That combination is useful if you expect to spend time editing, arranging, or listening through a full project. Its listed frequency range is 20 Hz to 20,000 Hz; I would treat that as a specification, not a guarantee that any one pair will reveal every mix issue.
The trade-off is that this is a Renewed product, not a new unit. It is described as professionally inspected and tested to work and look like new, but a refurbished purchase is a different proposition from buying new. In my opinion, it is the most practical pick here for someone who wants a familiar wired studio format and serviceable parts without needing planar drivers or a foldable frame.
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Updated: 2026-10-10 · 7 min read · Independent comparison
The Monolith M1070 is an over-ear, open-back planar headphone. Its 106mm planar driver and dual linear symmetry magnet array are the main reasons to consider it. The open grilles allow airflow around the driver, and the design is intended to create a broad soundstage with clear imaging. Those qualities may help when you are evaluating how instruments sit across a stereo field.
It has a 60-ohm impedance and wired 3.5mm connectivity. The supplied package includes memory-foam lambskin and velour ear pads, both removable. That gives you a choice of contact materials and a way to replace or change pads, though the sheets do not establish that one pad style is more accurate than the other. I would avoid assuming that a spacious presentation automatically translates to better mix decisions; you still need to check your work on other playback systems.
The comfort details include a padded, adjustable headband and plush pads. The listed weight is 20.5 ounces, so this is not the lightest option in the group. That matters for anyone who prefers minimal-feeling headphones or wears them through long sessions. The extra pad choice is useful, but the headphone’s size and weight are practical considerations.
I would choose the M1070 if the planar design and pad options are central to your decision. Its main trade-off is that it is heavier than the Austrian Audio model, and its specifications do not include a folding design for compact storage. Compared with the DT 990, it offers a different driver type and more explicit pad variety, but that alone does not make it the safer choice for every mixing workflow.
The Focal Clear MG is an open-back, wired over-ear headphone built around a magnesium speaker-driver dome. Its design also includes perforated microfibre ear pads, a honeycomb grille, and an internal grille shaped to follow the driver. Together, those details point toward a high-detail listening experience and an emphasis on an open presentation, though the construction features by themselves cannot tell you whether its tuning will suit your preferences.
At 55 ohms, it is specified with lower impedance than the DT 990 and M1070. Focal describes it as suitable for use with portable players, which may appeal if you want to move between a dedicated listening setup and a more compact source. The listed frequency range is 5 Hz to 28,000 Hz. As with any frequency-range figure, that is not a substitute for checking whether the headphone’s overall sound works for your decisions.
The physical materials are a significant part of its identity: the headband is covered with leather and microfibre, and the yoke is solid aluminum. The supplied contents include a cable, jack adapter, and carrying case. Those features make the Clear MG a considered option for someone who wants a substantial, carefully finished listening setup as well as an open-back design.
Austrian Audio Hi-X65
The Hi-X65 is the most explicitly production-oriented model in this group: it is described as designed for mixing and mastering, with an over-ear open-back construction. It uses a 44mm dynamic driver and the brand’s Hi-Xcursion design, which combines a ring magnet system with a copper-clad aluminum voice coil. The stated aim is a responsive driver movement, while the open-back format is intended for spacious, precise listening.
Its 25-ohm impedance is lower than the other models here. That can make it a reasonable candidate for a wider range of headphone outputs, although actual suitability still depends on the source. The listed frequency range runs from 5 Hz to 28 kHz. I would use those figures as context rather than as proof of how mixes will translate to speakers, earbuds, or other headphones.
Portability is a stronger point than it is on the other options. The Hi-X65 folds for storage and comes with a carrying case. The metal construction is intended to handle regular transport, and the included accessories include a quarter-inch adapter. The product information also lists 3-meter and 1.2-meter cable options, which suggests flexibility for a desk setup or a more compact listening arrangement.
The trade-off is that the provided details do not specify removable ear pads or describe their materials. If long-session comfort or pad replacement is a deciding factor, the DT 990 and M1070 offer clearer information on that point. Still, I would put the Hi-X65 near the top for someone who wants a purpose-built mixing and mastering headphone that can fold away between sessions.
How We Picked
I compared the published specifications and design features relevant to studio listening, including driver type, impedance, cable and portability details, and ear-pad construction.
The order is my independent editorial opinion based on those details and the needs of a shopper choosing headphones for production work.
They can be useful for critical listening because an open-back design allows air through the earcups and may create a spacious presentation. They do not isolate sound, so they are less suited to noisy rooms or recording situations where sound leakage matters.
The Austrian Audio Hi-X65 folds and includes a carrying case, making it the clearest portability choice from the listed features. The M1070 and DT 990 do not have a folding design specified here.
No. Impedance is one part of matching headphones to a source; it does not guarantee ideal output or sound on every device. The Hi-X65 is 25 ohms, while the DT 990 is 80 ohms, but buyers should still check the output they plan to use.
Not automatically. The M1070’s planar driver and open design are notable features, but driver type alone does not establish whether its sound will suit your decisions. Consider comfort, connectivity, and how reliably you can check a mix on other playback systems.
For mixing and mastering, I recommend the Amazon Renewed beyerdynamic DT 990 as the most straightforward choice here: it combines an 80-ohm wired design, replaceable ear pads, and a long cable. If planar construction and two supplied pad styles matter more to you, I would consider the Monoprice M1070 instead.
