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.

Our Picks

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.
Sennheiser HD 280 Pro Headphones

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.

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.
Audio-Technica ATH-M40x

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.

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.
HIFIMAN SUNDARA Closed-Back Planar Headphones

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.

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.
Audio-Technica ATH-M50x

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.

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.
beyerdynamic MMX 300 Pro

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.

What to Look for in a Closed-Back Headset

Key buying criteria so you get the right fit the first time.

  1. How much driver size you need

    Here driver size runs from 40mm on the ATH-M40x to 45mm on the ATH-M50x, a 13% spread. Start with the ATH-M50x if driver size decides it. The HD 280 Pro and the Sundara Closed-Back give no driver size figure, so 3 of 5 picks are compared here.

  2. Features beyond the spec table

    The Sundara Closed-Back: beechwood ear cups. The ATH-M50x: detachable cables. The MMX 300 Pro: closed-back isolation.

  3. Where your budget lands

    $50 to $100 buys the HD 280 Pro; $100 to $150 buys the ATH-M40x and the Sundara Closed-Back; $150 to $250 buys the ATH-M50x; $250 to $500 buys the MMX 300 Pro at our last check.

  4. Match the pick to your priority

    Getting up to 32 dB of listed passive attenuation for the least money: the HD 280 Pro. Buyers for whom price is not the deciding factor, since the HD 280 Pro costs less: the MMX 300 Pro.

  5. 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.
