How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a collapsible, do-everything closed-back studio headphone with swappable cables and a hard travel case, choose Audio-Technica ATH-M50x; if you need a closed-back monitoring headphone engineered to reject vibration and bleed in a demanding studio, choose Sennheiser HD 480.
• Audio-Technica ATH-M50x — biggest strength: 45mm neodymium drivers plus a collapsible, swiveling frame and detachable straight and coiled cables make it the more adaptable, travel-friendly pair.
• Audio-Technica ATH-M50x — biggest trade-off: Its 6.35mm jack and stainless-steel, over-ear build suit a desk and a bag more than a locked-down broadcast rack.
• Sennheiser HD 480 — biggest strength: 130 Ohm impedance, 130 dB max SPL, a geometrically angled earcup design and a Vibration Attenuation System point to a headphone built for precise, low-distortion monitoring in loud rooms.
• Sennheiser HD 480 — biggest trade-off: It arrives as a bundle with a desktop stand and a coiled cable, and its oval on-ear earpieces sit differently from a full circumaural fit — so it is less of a fold-flat commuter headphone.
• Pick the ATH-M50x if you move between studio, desk and travel and want one pair to do all three.
• Pick the HD 480 if you track, mix or monitor in a space where isolation and signal integrity matter more than portability.
The ATH-M50x is Audio-Technica's flagship M-series model, and the spec sheet reads like a headphone designed to be used everywhere rather than admired in one spot. The 45mm neodymium magnet drivers cover a 15 Hz to 28,000 Hz range, which is a wide sweep for a closed-back monitor. Sensitivity is rated at 99 dB, so it plays loud without demanding a monster amp. It is a wired, over-ear design with a 6.35mm jack and stainless-steel enclosure material in black.
What it does best is flexibility. The closed-back design delivers isolation with minimal bleed, which is exactly what you want when a mic is live in the same room. The circumaural ear pads are built for cushy comfort across long sessions, so a marathon mix or a DJ set does not turn into a pressure headache. Then there is the folding story: collapsible frame, swivel earcups, and detachable cables in both straight and coiled versions. That is a genuinely rare combination — most monitoring headphones pick one and stop.
The package also includes a molded EVA protective case with a tough fabric exterior and plush interior, and the model carries a 2-year warranty.
Who should buy it: producers who record and mix at a desk, DJs, podcasters, and anyone who wants one closed-back pair for the studio and the commute. The collapsible design and hard case make it a legitimate grab-and-go headphone.
Sennheiser HD 480: Who It's For
The HD 480 PRO is the more specialized instrument of the two. It is a wired, closed-back, over-ear studio headphone with dynamic 38mm transducers covering 3 Hz to 28,700 Hz — an unusually deep low-end extension on paper. Impedance is 130 Ohm, and max SPL is rated at 130 dB. Those two numbers together tell a story: this is a headphone designed to stay composed when you push it, and to pair with an interface or headphone amp rather than a phone dongle.
The engineering story is the interesting part. Sennheiser describes multiple stages of passive sound shielding and a proprietary Vibration Attenuation System that reduces distortion and keeps the signal honest. The earcups are geometrically angled to optimize transducer placement for a more consistent listening position. Taken together, that is a headphone aimed at accuracy over excitement — uncolored and honest rather than flattering.
It ships with passive noise cancellation by way of its closed-back sealing, both 3.5mm and 6.35mm jacks, and a coiled cable. The bundle also includes a desktop headphone stand, which nudges the whole thing toward a fixed studio position. Weight is listed at 1.3 pounds. Warranty is 1 year limited.
One note worth flagging plainly: the product information lists ear placement as on-ear with oval earpieces, even though the title and description describe over-ear circumaural use. If fit is critical to you, that discrepancy is worth resolving before you commit — oval pads that sit on the ear feel very different from pads that fully surround it.
Who should buy it: engineers and producers working in treated rooms who want a low-distortion, high-headroom reference pair, and anyone who values a coiled cable and a stand as part of the setup.
Who should skip it: commuters, travelers, and anyone who wants a folding headphone. There is no collapsible design here, no swivel mechanism listed, and the 130 Ohm load means weaker sources will struggle.
• Best for portability and travel → Audio-Technica ATH-M50x. Collapsible frame, swivel earcups, detachable cables, and a molded EVA case.
• Best for low-distortion monitoring in a loud room → Sennheiser HD 480. Vibration Attenuation System plus multiple stages of passive shielding.
• Best for cable flexibility → Audio-Technica ATH-M50x. It ships with both a straight and a coiled detachable cable, not just one.
• Best for headroom and amp pairing → Sennheiser HD 480. 130 Ohm impedance and 130 dB max SPL.
• Best for low-end extension on paper → Sennheiser HD 480. 3 Hz versus the ATH-M50x's 15 Hz at the bottom of the range.
• Best for a fixed desktop setup → Sennheiser HD 480. The bundle includes a desktop headphone stand and a coiled cable.
• Best for long-session comfort → both, in different ways. The ATH-M50x leans on circumaural padding; the HD 480 leans on an angled earcup design and a secure fit.
• Best for DJ and recording work where bleed matters → Audio-Technica ATH-M50x. The isolation-with-minimal-bleed design is stated plainly and suits live mics.
I would buy the Audio-Technica ATH-M50x. In my opinion, the collapsible frame, swivel earcups, two detachable cable types, hard case and 2-year warranty make it the more useful headphone for the way most people actually work — desk, studio, bag, repeat. The HD 480 is the more specialized tool and I would genuinely recommend it to someone mixing in a treated room who wants maximum isolation and headroom. But if you can only own one closed-back pair and you move around, the ATH-M50x covers more ground.
what are closed back studio headphones
Closed-back studio headphones have sealed earcups that block outside sound from reaching your ears and keep your audio from leaking out. That makes them the right choice for recording vocals or instruments with a live mic, for DJ work, and for monitoring in rooms where you do not want bleed. The Audio-Technica ATH-M50x and Sennheiser HD 480 are both closed-back designs built for exactly that job.
what are the best closed back studio headphones
There is no single answer — it depends on how you work. In my opinion, the Audio-Technica ATH-M50x is the better all-rounder because it folds, swivels, and ships with both straight and coiled detachable cables plus a hard case. The Sennheiser HD 480 is the stronger pick if you want 130 Ohm impedance, 130 dB max SPL and a Vibration Attenuation System for low-distortion monitoring. Match the headphone to your room and your source, not to a label.
Open-back studio headphones have vented earcups that let air move freely, which typically produces a wider, more natural sense of space but leaks sound both ways and offers little isolation. They are usually reserved for mixing and critical listening in a quiet room. Both headphones compared here are closed-back, so neither trades isolation for that open, airy presentation.
Do I need an amp for the Sennheiser HD 480?
Its 130 Ohm impedance is noticeably higher than the ATH-M50x's 99 dB sensitivity rating suggests you need for the Audio-Technica. In practice, a laptop headphone jack may not drive the HD 480 to its full potential. An audio interface or dedicated headphone amp is the safer pairing, especially given the 130 dB max SPL rating.
