How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired, over-ear monitor built for tracking and mixing at a desk, choose Audio Technica ATH-M20x; if you need wireless noise-cancelling earbuds for commuting, calls and travel, choose Amazon Renewed Sony WF-1000XM6. They are not really rivals — one is a cable-first studio tool, the other is a Bluetooth-first lifestyle pair — so the right call comes down to how you actually listen.
• Audio Technica ATH-M20x — biggest strength: a true wired, closed-back over-ear design with 40 mm dynamic drivers, a 15 Hz–20 kHz range and a single-side 9.8' cable with a 3.5 mm plug plus a 1/4" snap-on adapter, so it plugs straight into interfaces, mixers and receivers.
• Audio Technica ATH-M20x — biggest trade-off: it is wired and passive. No Bluetooth, no active noise cancelling, no charging case. The bundle adds a headphone holder and a protective case, but portability still means carrying a cable.
• Amazon Renewed Sony WF-1000XM6 — biggest strength: adaptive active noise cancelling with dual processors and eight microphones, up to 24 hours of total playback (8 in the buds, 16 in the case) and a five-minute quick charge for about an hour of listening.
• Amazon Renewed Sony WF-1000XM6 — biggest trade-off: it is a renewed wireless in-ear product with a 90-day limited warranty, no headphone jack, and battery behaviour that depends on how the previous owner treated it. No cable option if the battery runs flat.
• Who each is for: the ATH-M20x suits home recordists, musicians and anyone mixing at a desk. The WF-1000XM6 suits commuters, call-heavy workers and travellers who want quiet and no wires.
The ATH-M20x is the definition of a no-drama studio headphone. Audio-Technica built it for studio tracking and mixing, and the spec sheet backs that up: 40 mm drivers with rare-earth magnets and copper-clad aluminium voice coils, tuned for enhanced low-frequency performance. The frequency range runs 15 Hz to 20 kHz, which covers the full musical spectrum you need when you're checking a bass line or hunting for mud in a mix.
The design choices are all about work, not lifestyle. The circumaural earcups contour around the ears rather than pressing on them, which gives you solid isolation in loud rooms — useful when you're tracking vocals next to a drummer or monitoring in a noisy home setup. The earcups swivel 15°, the headband and pads are generously cushioned, and the enclosure uses aluminium and copper. The cable exits from the left earcup only, which keeps channel identification simple and cuts down on tangling, and it terminates in a 3.5 mm mini plug with a 1/4" snap-on adapter included for interfaces, mixers and stereo receivers. In the box you also get a headphone holder and a protective case, which is a nice touch for keeping a desk tidy between sessions.
Who should buy it: home studio owners, singer-songwriters, podcasters, students learning to mix, and anyone who wants one dependable wired pair that lives on a desk or a stand. If your workflow is "plug into the interface, hit record," this is the shape of headphone that fits.
Who should skip it: anyone who wants to walk around, take calls on the street, or block out a plane cabin. There's no Bluetooth, no active noise cancelling and no battery — it's a wired monitor, and that's the whole point. If you need wireless freedom, this is the wrong tool.
The WF-1000XM6 is a completely different animal: true wireless in-ear earbuds with active noise cancellation, sold here as an Amazon Renewed unit. The headline feature is the noise cancelling — dual processors and eight adaptive microphones that adjust in real time, driven by the HD Noise Cancelling Processor QN3e, which Sony says is three times faster than the QN2e used in the WF-1000XM5. Put plainly, the design intent is to erase your surroundings so the music sits front and centre.
Sound-wise, Sony says the buds were developed with mastering audio engineers to deliver studio-level clarity in a compact earbud, with an improved DAC and amplifier. Call quality gets its own hardware: dual beamforming microphones, a bone conduction sensor and AI-powered noise reduction to isolate your voice and cut wind and background noise. Controls are touch-based on the earbuds, with voice and gesture commands, so you can adjust volume, manage playback and mute the mic without reaching for your phone.
Battery is the other big story. You get up to 24 hours of total playback — 8 hours in the earbuds and 16 more in the charging case — plus a five-minute quick charge for about an hour of listening when you're in a hurry. A full charge takes roughly 1.5 hours. Sony's Sound Connect app includes a Battery Care mode to reduce long-term wear, which matters more than usual on a renewed product. Connectivity is Bluetooth 5 with no headphone jack at all, and the package includes the charging case, four sizes of earbud tips and a USB-C cable. The unit is black plastic, weighs about 13 g, and carries a 90-day limited warranty.
Who should buy it: commuters, remote workers on back-to-back calls, frequent flyers, gym-goers and anyone who wants strong noise cancelling and no cable in sight. The renewed angle suits buyers who want the feature set without paying new-unit money — just go in with realistic expectations about a used battery.
Who should skip it: anyone who needs a wired connection for zero-latency monitoring, anyone who dislikes in-ear fit, and anyone who wants a long manufacturer warranty rather than a 90-day one. If you're mixing a record, earbuds with a Bluetooth link are not the right reference.

In my opinion, these two don't compete for the same slot on your desk — they compete for different hours of your day. If your priority is making music, tracking, mixing or monitoring through a wired connection, I'd buy the Audio Technica ATH-M20x. It does one job and does it without batteries, pairing or latency. If your priority is blocking out the world on a train or a busy office and you want the Sony feature set for less than a new pair, I'd buy the Amazon Renewed Sony WF-1000XM6, and I'd check the current price on Amazon and read the renewed-condition details before committing. Serious studio work? Audio-Technica. Life on the move? Sony.
FAQ
what are the best wired studio headphones
what are wired headphones
Wired headphones connect to your device with a physical cable instead of Bluetooth. The ATH-M20x is a wired model with a 9.8' cable exiting the left earcup and a 3.5 mm jack; the Sony WF-1000XM6 has no jack at all and connects only over Bluetooth 5.
what headphones do professional studios use
Studios use closed-back and open-back monitors that plug into interfaces, mixers and receivers. The ATH-M20x fits that pattern with its circumaural isolation, 15° swiveling earcups and 1/4" snap-on adapter, which is exactly the kind of connectivity studio gear expects.
are all studio headphones wired
No. Plenty of modern headphones marketed for studio-style sound are wireless — the Sony WF-1000XM6, for example, is a Bluetooth in-ear model with active noise cancelling and up to 24 hours of total playback. But for latency-free tracking, a wired pair like the ATH-M20x is the safer pick.
