Sony Brings Back the WH-1000XM4 as the $299.99 WH-1000XM4C — With a Battery You Can Reportedly Replace

Six years after it launched, the Sony WH-1000XM4 is back. On 7 September 2026 Sony Electronics announced the WH-1000XM4C — a model the company itself also refers to as the "M4 2nd Gen" — at $299.99 USD / $429.99 CAD, with availability given as Fall 2026 through Sony, Amazon, Best Buy and authorised retailers. It comes in Black, Platinum Silver and Lavender, the last of which is exclusive to Sony and Amazon.

Reviving a six-year-old design is unusual enough on its own. What makes it a story rather than a curiosity is the reason several outlets have given for the timing.

The replaceable-battery angle

TechRadar and Digital Trends both report that the WH-1000XM4C's battery is user-replaceable, and both frame that change as a response to incoming European law. It is worth being precise about the provenance here: Sony's own US press release does not foreground a replaceable cell, and Engadget's write-up does not mention it at all. Sony has not publicly said that the redesign was carried out for regulatory compliance. The regulatory reading is the reporting of TechRadar and Digital Trends, set against the text of the law itself.

That law is Regulation (EU) 2023/1542. Article 11 applies from 18 February 2027 and requires that portable batteries incorporated into products be readily removable and replaceable by the end user at any point during the product's lifetime. The regulation's definition of "end user" is deliberately unforgiving: an adult with no special skills, tools or qualifications. In practical terms, a sealed-battery flagship headphone becomes unsellable in the EU once that date passes.

Read against that deadline, reissuing a beloved 2020 design with a serviceable cell looks less like nostalgia and more like engineering groundwork — a chance to work through the mechanical problem on a known platform. Sony has not announced a price for replacement batteries, and no source we have gives one.

What has changed, and what has not

Multiple outlets confirm that the WH-1000XM4C retains the QN1 noise-cancelling processor and the four-microphone array of the 2020 original, and that the industrial design is unchanged. This is the same headphone, visually and in its core ANC hardware.

The additions Sony does highlight are a 10-band equalizer, which the company describes as bringing its latest sound tuning to meet modern listening tastes, plus a "Quick Access" one-touch shortcut for launching a streaming service, and multipoint Bluetooth.

The subtraction is battery life. The WH-1000XM4C is rated at 27 hours with ANC on, down from the original WH-1000XM4's 30-hour figure — a point Engadget states explicitly. Quick charging is 3 minutes for an hour of listening. Three hours of endurance is a real cost, and if the replaceable-cell reporting is accurate, it is the kind of cost you would expect: a battery designed to come out is a battery constrained by the housing, the connector and the door that lets it out. Whether that trade reads as sensible depends entirely on how much a serviceable cell is worth to a given listener.

On price, the XM4C arrives $50 below the original WH-1000XM4's August 2020 launch price of $349.99, a difference Engadget notes. 9to5Google reports that pre-orders are expected to ship around 30 September; Sony's own stated window is simply Fall 2026.

Sony's Masaaki Hori, Vice President of personal entertainment, said the release "reflects continued consumer interest in a headphone model recognized globally."

Two more headphones announced the same day

The XM4C did not arrive alone. Sony also refreshed the middle and entry rungs of its wireless range.

• WH-CH730N — $179.99 USD / $249.99 CAD, September 2026. Over-ear with active noise cancelling, rated at up to 50 hours of battery with ANC on, and a 3-minute quick charge for an hour of playback. Sony lists Dual Noise Sensor technology, Precise Voice Pickup with AI noise reduction, LE Audio, multipoint connection and Fast Pair / Swift Pair. Colours: White, Pink, Blue, Black and Oat.
• WH-CH530 — $69.99 USD / $99.99 CAD, September 2026. This one is on-ear, not over-ear, despite some early coverage suggesting otherwise. Sony rates it at up to 55 hours of battery, with a 3-minute quick charge for 90 minutes of playback. Features include a customisable EQ, AI noise reduction, a five-step volume control aimed at hearing protection, LE Audio and multipoint. Colours: Black, Cobalt, White, Pink, Coral and Mint.

A note on naming: 9to5Google refers to the entry model as the "WH-CH530N" and describes it as over-ear. Sony's own press release calls it the WH-CH530 and specifies an on-ear design, and that is what we have followed here.

Why this matters beyond one product

Consumer electronics rarely reverse direction, and headphones have spent a decade getting more sealed, not less. Regulation (EU) 2023/1542 sets a hard date at which that trend stops for anything sold into the European market, and the first responses to it are now appearing on price lists. Sony's chosen vehicle is a design that already has six years of goodwill behind it and no need to prove itself acoustically — which, whatever the company's stated reasoning, is a low-risk place to solve a difficult mechanical problem.

What remains unanswered is the servicing economics. Without an announced replacement-battery price or a stated availability window for spare cells, the practical value of a user-replaceable design in a $299.99 headphone is still an open question. Full specifications, colours and pricing are in Sony's press release, with further coverage at What Hi-Fi.
