If you want a lightweight, collapsible wired headphone that isolates you from a loud room and stays comfortable through long sessions, choose Audio-Technica ATH-M30x; if you need a wider frequency range, a detachable coiled cable you can replace, and a carrying bag for transport, choose Shure SRH440. Neither is a wireless sports earbud, and neither is built for sweat-soaked exercise — if "headphones for exercise" is your actual goal, these two wired studio monitors are the wrong category entirely. But plenty of people shop these models anyway, so let me sort out who each one really fits.
• Audio-Technica ATH-M30x — biggest strength: 40 mm dynamic drivers tuned for mid-range detail, a circumaural closed-back design that seals around the ears for strong isolation, and a collapsible frame that packs down small. Lightweight at 0.22 kg with an aluminum enclosure.
• Audio-Technica ATH-M30x — biggest trade-off: Wired only, with a fixed single-side cable and passive (not active) noise cancellation. You get isolation from the seal, not from electronics.
• Shure SRH440 — biggest strength: A wider stated frequency range (10 Hz to 22 kHz vs. 20 Hz to 20,000 Hz), a detachable coiled cable that can be swapped or replaced, and a carrying bag plus threaded 1/4" gold-plated adapter in the box.
• Shure SRH440 — biggest trade-off: Heavier build (1.6 lb), a plastic enclosure, and a 6.35 mm jack that assumes you're plugging into studio gear rather than a phone.
• Pick the ATH-M30x if you want a light, foldable wired monitor for tracking, field recording, video editing, or dialog work where isolation matters.
• Pick the SRH440 if you want a home/studio headphone with a replaceable cable, extended range, and a bag for carrying it between rooms and sessions.
The ATH-M30x is a closed-back, over-ear wired headphone built around 40 mm dynamic drivers with rare-earth magnets and copper-clad aluminum voice coils. In plain terms, that's a design aimed at mid-range definition — the part of the spectrum where voices, guitars, and dialog live. If you're editing a video, tracking a vocal, or cutting dialog, mid-range clarity is exactly what you want to hear, and this is the tuning Audio-Technica went for.

The circumaural shape contours around the ear rather than pressing on it, which does two things: it keeps the fit comfortable over long stretches, and it seals off outside noise. The passive noise cancellation here is purely mechanical — the pads and the closed cups block sound. That's genuinely useful in a loud room, a noisy edit bay, or next to a humming computer. There's no battery, no app, no active processing.
The build is where it earns its keep for portable studio work: an aluminum enclosure, a weight of just 0.22 kg, a single-side cable exit so the cord doesn't tangle across your chest, and a collapsible frame. It ships with a protective case, a 3.5 mm jack, a screw-on 6.3 mm (¼") adapter, and a 2-year parts-and-labor warranty.
Buy it if you need a light, foldable, isolating wired headphone for field recording, home studio tracking, AV post production, or dialog work — and you're fine plugging into a 3.5 mm source or using the included adapter.
Skip it if you need a detachable cable, a wider frequency range, or a headphone you can wear while working out. This is not an exercise headphone — no sweat resistance is claimed, and the fixed cable is a liability if you snag it.
The SRH440 is Shure's closed-back, circumaural studio headphone, positioned for home and studio recording. Its headline spec is the frequency range: 10 Hz to 22 kHz, which extends lower at the bottom and higher at the top than the ATH-M30x's 20 Hz–20,000 Hz. The impedance is 44 ohm, close enough to the M30x's 38 ohm that both will behave similarly on typical headphone outputs.
The design decisions tell you who it's for. The cable is detachable and coiled — coiled so it doesn't sprawl across a desk, detachable so a failed cable doesn't retire the whole headphone. That's a meaningful longevity difference versus a fixed cable, and it's the single most practical advantage Shure built in here.
In the box you get the headphone, a threaded 1/4" gold-plated adapter, a carrying bag, and a user guide. The jack is 6.35 mm, which signals the intended source: an interface, a mixer, a headphone amp — studio gear. You'll need an adapter or a 3.5 mm-to-6.35 mm converter to use it with a laptop or phone.
The trade-offs are real. At 1.6 lb it's noticeably heavier than the 0.22 kg ATH-M30x, and the enclosure is plastic rather than aluminum. It's collapsible, but with that weight and a bag rather than a hard case, it's a stay-put studio tool more than a toss-in-your-bag commuter headphone.
Buy it if you want a home/studio headphone with a replaceable coiled cable, extended frequency response, a bag for transport, and you're plugging into proper audio gear.
Skip it if you want the lightest possible option, an aluminum build, or something you can wear on a run. It's also not a sports earbud — no water or sweat resistance is specified.
• Best for mid-range detail and dialog/vocal work → Audio-Technica ATH-M30x. Its 40 mm drivers are explicitly tuned for enhanced mid-range definition.
• Best for extended frequency range → Shure SRH440. 10 Hz–22 kHz beats 20 Hz–20,000 Hz on paper at both ends.
• Best for replaceable cable and long-term durability → Shure SRH440. Detachable coiled cable means a broken cord is a cheap fix, not a dead headphone.
• Best for lightweight, foldable portability → Audio-Technica ATH-M30x. 0.22 kg, collapsible, aluminum enclosure, single-side cable exit.
• Best for comfort over long sessions → Audio-Technica ATH-M30x, in my opinion — the lighter weight and circumaural contour favor extended wear.
• Best for studio-desk use with pro gear → Shure SRH440. The 6.35 mm jack and coiled cable are made for an interface or mixer, not a phone.
• Best for plug-and-play with everyday devices → Audio-Technica ATH-M30x. The 3.5 mm jack works directly with laptops and phones, with a ¼" adapter included for gear.
• Best for exercise or workouts → neither. If you're hunting for best spatial audio wireless earbuds for exercise or noise canceling sports earbuds, these two wired studio headphones aren't in that conversation at all.
For studio and monitoring work, I'd buy the Audio-Technica ATH-M30x. In my opinion, the combination of a light 0.22 kg aluminum build, a collapsible frame, 3.5 mm plug-and-play connectivity, and strong passive isolation from the circumaural seal makes it the more versatile everyday monitor — and the one I'd actually reach for across editing, tracking, and casual listening.
I'd only switch to the Shure SRH440 if the detachable coiled cable and the wider 10 Hz–22 kHz range matter more to you than weight and an aluminum body. And to be clear about the exercise angle: if your real goal is headphones for exercise, skip both and look at actual sweat-resistant wireless sports models instead.
Is the Audio-Technica ATH-M30x or the Shure SRH440 better for studio recording?
Both are closed-back studio headphones with similar impedance (38 vs. 44 ohm). The ATH-M30x leans toward mid-range detail and lighter, foldable portability; the SRH440 offers a wider stated frequency range and a detachable cable. For pure home/studio recording with pro gear, either works — pick based on cable replaceability vs. weight.
No. The ATH-M30x uses passive noise cancellation — the circumaural seal blocks outside sound mechanically. The SRH440 relies on sound isolation from its closed-back design. Neither has battery-powered or electronic ANC.
It has a 6.35 mm jack, so not directly. You'd need a 3.5 mm adapter or a suitable cable. The ATH-M30x is easier here, since it uses a 3.5 mm jack and includes a screw-on ¼" adapter for studio gear.
