Five headsets compared, from the HD 280 Pro to the MMX 300 Pro, with the trade-offs of each named.

12 min read5 products evaluated

Closed-back cups keep your audio in and room noise out, which suits shared spaces and streaming. Every pick is a closed design, ordered from the lowest price.
This is a research roundup, not a lab test: driver size, connection and design come from each maker's published specs; a missing driver size is flagged, not filled in, and no figure here comes from our own testing.

Lowest Price Here1 of 5
Sennheiser HD 280 Pro Headphones
Sennheiser's HD 280 Pro is a closed studio headphone with up to 32 dB of listed passive attenuation.
Best for
- Getting up to 32 dB of listed passive attenuation for the least money.
Skip if
- Worth skipping when no built-in microphone is a problem.
Why we like it
It blocks a noisy room well but has no mic. Like the MMX 300 Pro, it has a wired 3.5mm connection, while the Sundara Closed-Back uses a wired connection. You also get a closed design for shared rooms and a foldable frame.
A 3.5mm plug means it works with a controller or front-panel jack; on PC, a separate mic and headphone jack may need a splitter. Worth noting: no charging or pairing needed. It undercut the ATH-M40x and every other pick on price at the time of writing. The maker doesn't give its driver size; if that figure matters, the ATH-M50x comes in at 45mm.
Key specs
- Connection
- Wired 3.5mm
- Design
- Closed-back
- Microphone
- None
Pros
- No charging or pairing needed
- Up to 32 dB of listed passive attenuation
- Closed design for shared rooms

Also Consider2 of 5
Audio-Technica ATH-M40x
Audio-Technica's ATH-M40x uses 40mm drivers and 90-degree swiveling earcups.
Best for
- Buyers who want 40mm drivers.
Skip if
- Skip it if this is a deal-breaker for you: no built-in microphone.
Why we like it
It is the lower-priced closed studio headphone in the line. Its circumaural ear cups seal around the ears for isolation in loud rooms, and the pads and headband use professional-grade materials. It is built for studio monitoring as much as gaming.
Its 40mm drivers use rare earth magnets and copper-clad aluminium voice coils. Its 40mm driver size is the smallest in this group; the ATH-M50x leads at 45mm. It also comes with detachable cables.
You also get this: no charging or pairing needed. Its price falls between the HD 280 Pro and the Sundara Closed-Back, based on our last check.
Key specs
- Driver size
- 40mm
- Connection
- Wired, detachable cables
- Design
- Closed-back
- Microphone
- None
Pros
- No charging or pairing needed
- 40mm drivers
- 90-degree swiveling earcups
- Detachable cables
Cons
- No built-in microphone
- Driver size trails the ATH-M50x (45mm)
- Costs more than the HD 280 Pro at the time of writing
Strong Alternative3 of 5
HIFIMAN SUNDARA Closed-Back Planar Headphones
The Sundara Closed-Back is built around a closed-back design that leaks less sound, with beechwood ear cups on top.
Best for
- Buyers who want closed-back design that leaks less sound.
Skip if
- Skip it if this is a deal-breaker for you: no built-in microphone.
Why we like it
This is the closed-back Sundara, which keeps sound in and outside noise out, unlike the open original. Its NEO supernano diaphragm is 80% thinner than common designs. Closed-back planars are rare, so it suits planar sound in a shared room where open-backs would leak.
You get a wired connection here, which sets it apart from the MMX 300 Pro and its a wired 3.5mm connection. A closed-back planar magnetic design is unique to it among these picks, while the ATH-M40x uses a closed-back design. You also get a detachable cable.
It was priced above the ATH-M40x and below the ATH-M50x at the time of writing. There is no published driver size figure, whereas the ATH-M50x comes in at 45mm.
Key specs

- Wired
- Design

Pros

- Closed-back design that leaks less sound

Worth a Look4 of 5
Audio-Technica ATH-M50x
Audio-Technica's ATH-M50x uses 45mm drivers in a closed-back studio design with detachable cables.
Best for
- Buyers who want 45mm large-aperture drivers.
Skip if
- Pass on it if no built-in microphone rules it out for your setup.
Why we like it
It has no mic. Its ear cups swivel 90 degrees for one-ear monitoring, and the extended frequency range includes deep, accurate bass. Its 45mm large-aperture drivers use rare-earth magnets and copper-clad aluminum voice coils.
The circumaural cups seal around the ears, which helps it isolate sound in a loud room. On driver size it ties with the MMX 300 Pro at 45mm. You also get this: no charging or pairing needed. When we checked, only the Sundara Closed-Back and cheaper picks cost less, and the MMX 300 Pro cost more.
Key specs
- Driver size
- 45mm
- Connection
- Wired, detachable cables
- Design
- Closed-back
- Microphone

Pros
- No charging or pairing needed

Premium Pick5 of 5
beyerdynamic MMX 300 Pro
The MMX 300 Pro is built around a plug-in design with no software needed, with closed-back isolation on top.
Best for
- Buyers for whom price is not the deciding factor, since the HD 280 Pro costs less.
Skip if
- Price-first buyers should look at the HD 280 Pro, which cost less when we checked.
Why we like it
On the spec sheet, it offers a 45mm driver size. On driver size it ties with the ATH-M50x at 45mm. It shares a wired 3.5mm connection with the HD 280 Pro; the Sundara Closed-Back goes with a wired connection.
A 3.5mm plug means it works with a controller or front-panel jack; on PC, a separate mic and headphone jack may need a splitter. Worth noting: no charging or pairing needed. Another plus: condenser microphone, the only one here.
Before buying, weigh one limit: costs more than the HD 280 Pro at the time of writing. At our last price check it topped the group, with the ATH-M50x the nearest cheaper option.

How We Chose These Closed-Back Headsets
Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.

- The figures behind the order
- We lined up five headsets on driver size, connection, design and microphone from manufacturer specifications. We did not test them in-house, and driver size is missing for at least one pick.
- The shared baseline
- All 5, from the HD 280 Pro to the MMX 300 Pro, state connection, design and microphone.
- Where the specs have gaps
- The HD 280 Pro and the Sundara Closed-Back give no driver size.
- Price range
- At our last check the picks ran from the HD 280 Pro ($50 to $100) to the MMX 300 Pro ($250 to $500).

Headphones on a red stand next to an amplifier and bookshelf speakers Open-back or closed-back
Open-back headphones sound more spacious and feel cooler, but they leak sound and block little outside noise. Closed-back models isolate better in shared rooms.
Choose open-back only if you play in a quiet room on your own.
