If you want semi-open, wired headphones for a more spacious listening setup for work, choose beyerdynamic DT 880; if you need closed-back headphones that help reduce ambient distractions, choose Audio-Technica ATH-M20x. The key difference is how their designs handle the space around you: the DT 880 is semi-open, while the ATH-M20x is closed-back and built for sound isolation.
• beyerdynamic DT 880 strength: Semi-open, over-ear design with a stated frequency range of 5 Hz to 35,000 Hz. Trade-off: Wired, with no listed noise-control feature.
• Audio-Technica ATH-M20x strength: Closed-back design intended to minimize ambient distractions, plus a 3-meter cable. Trade-off: Its stated frequency response reaches 20,000 Hz, and it is also wired.
• Choose DT 880 if you want semi-open headphones for focused listening at a desk and can use a wired connection.
• Choose ATH-M20x if you want a closed-back design for a home studio or another environment where reducing surrounding sound matters.
• Neither model is wireless, so neither is a fit if your work setup requires Bluetooth or cable-free movement.
The DT 880 is a wired, over-ear headphone with a semi-open design. That construction is the defining choice here. It is suited to a work setup where you want headphones for music, games, or other listening at a desk, and where the semi-open format makes more sense than a closed-back design. Its stated frequency range is 5 Hz to 35,000 Hz, and it has a 32-ohm impedance. Those figures describe its published audio specifications; they do not, on their own, guarantee how it will sound with every device or in every room.
For connection, the DT 880 uses a 3.5 mm jack and comes with a pre-installed screw-on 1/4-inch adapter. That gives you a practical way to connect it to devices with either of those jack sizes, rather than relying on a wireless link. It has no listed noise-control feature, so I would not choose it for a noisy shared office if the goal is to shut out distractions. Its semi-open construction also makes it a less natural fit when you need a more enclosed listening experience.
The DT 880 makes sense for someone who plans to sit down, connect a cable, and listen without needing Bluetooth. It may suit desk-based tasks such as editing, gaming, or focused music listening, provided the semi-open design fits the room and the people nearby. The included adapter is useful if your setup has a 1/4-inch headphone connection, while the 3.5 mm jack covers compatible devices such as tablets or phones.

Audio-Technica ATH-M20x: Who It's For
The ATH-M20x is a wired, closed-back over-ear headphone designed for monitoring. Its closed-back construction is described as helping minimize ambient distractions, which makes it the more straightforward choice between these two for a home workspace where surrounding sound can interrupt concentration. It has a 40 mm dynamic driver and a stated frequency response of 15 Hz to 20,000 Hz. Those published details can help you compare the designs, but they do not replace your own listening priorities.
Its 3-meter straight cable exits on the left side, a useful detail for a stationary desk or studio setup where you want some reach between the headphones and your equipment. The connection is a 3.5 mm jack. There is no Bluetooth connection listed, so the cable is part of the everyday setup rather than an optional fallback. The package described here also includes a desktop stand for storage and display, which may be handy if you want a dedicated place to put the headphones when you finish work.
Who should skip it: Skip the ATH-M20x if you specifically want semi-open headphones, a wireless connection, or the DT 880’s broader stated frequency range.
• Best for a semi-open listening design → beyerdynamic DT 880. Its semi-open construction is the central reason to choose it over the ATH-M20x’s closed-back format.
• Best for reducing ambient distractions → Audio-Technica ATH-M20x. Its closed-back design is described as helping minimize surrounding sound.
• Best for a longer cable run at a desk → Audio-Technica ATH-M20x. Its straight cable is 3 meters long and exits from the left side.
• Best for a 1/4-inch headphone connection → beyerdynamic DT 880. It includes a screw-on 1/4-inch adapter pre-installed on its 3.5 mm jack.
• Best for a stated frequency range extending lower and higher → beyerdynamic DT 880. Its range is listed as 5 Hz to 35,000 Hz, compared with 15 Hz to 20,000 Hz for the ATH-M20x.
• Best for a bundled storage stand → Audio-Technica ATH-M20x. The described package includes a desktop stand.
• Best for wireless work calls → neither. Both models are wired, and neither data sheet lists Bluetooth or a microphone.
• Best for a quieter, more enclosed listening setup → Audio-Technica ATH-M20x. Its closed-back design is the more relevant feature for that need.
The phrase “open ear headphones for work” can point shoppers toward a particular style, but neither of these models is described as an open-ear headphone. The DT 880 is semi-open and over-ear; the ATH-M20x is closed-back and over-ear. That distinction matters if you want your ears uncovered or need to stay especially aware of sounds around you.
My Verdict
For work at a desk, I would choose the Audio-Technica ATH-M20x if minimizing ambient distractions is the priority. Its closed-back design, 3-meter cable, and included desktop stand give it a clear use case for a fixed home-studio or office setup. I would choose the beyerdynamic DT 880 instead when I specifically wanted a semi-open design, its 5 Hz to 35,000 Hz stated range, or the included 1/4-inch adapter. My recommendation for work is the ATH-M20x, as long as a wired, closed-back headphone suits your space.
Before choosing, think about how you work and what is around you. If your desk is in a shared room, the ATH-M20x’s closed-back design and stated focus on minimizing ambient distractions are relevant advantages. If you mainly listen in a quieter space and prefer a semi-open design, the DT 880 is the more fitting option. These designs are not interchangeable, so your room and listening habits should weigh more heavily than a single specification.
Check your equipment’s headphone connection, too. Both products list a 3.5 mm jack. The DT 880 additionally includes a pre-installed 1/4-inch screw-on adapter, while the ATH-M20x has a 3-meter straight cable with a left-side exit. That length may be convenient at a desk, but a fixed cable is still a constraint if you regularly move away from your setup.
Finally, be clear about what these headphones do not promise in the supplied specifications. Neither is listed as Bluetooth-enabled, and neither sheet identifies a microphone. If your work depends on taking calls without a separate mic, or you need to walk around without a cable, look for those features explicitly in the product information before choosing.

The ATH-M20x is the more suitable choice based on its closed-back design, which is described as helping minimize ambient distractions. The DT 880 is semi-open and has no noise-control feature listed.
The DT 880 is listed at 5 Hz to 35,000 Hz, while the ATH-M20x is listed at 15 Hz to 20,000 Hz. Those are specification differences, not a guarantee that one will sound better to every listener.
