Sony is reviving its acclaimed WH-1000XM4 headphones as the WH-1000XM4C, six years after the original launch and one year after discontinuation. The move matters because it shows how slowly wearable hardware innovation moves, even as demand for compact, all-day audio devices keeps growing.
What actually happened
Sony announced the WH-1000XM4C on 7 September 2026, according to The Verge. The headphones share the exact visual design of the 2020 original, including its folding hinge, but add a new lavender color option. They use the same QN1 processing chip and four-microphone array for noise cancellation as the XM4. Sony updated the sound profile and expanded the EQ from 5 bands to 10 bands, plus added a gaming preset. The XM4C support Bluetooth 6 instead of Bluetooth 5. Battery life dropped slightly, to 27 hours with active noise cancellation on, down from 30 hours on the original XM4. The WH-1000XM4C will cost $300 (USD) and arrive later this fall, $50 less than the original XM4's launch price.
How we got here
Sony released the original WH-1000XM4 in fall 2020, during an intense noise-canceling rivalry with Bose. The XM4 topped best-headphone lists for years on the strength of sound quality, ANC performance, and a compact folding design. Sony moved away from that compact form with the WH-1000XM5 in 2022, then partially returned to it with the WH-1000XM6 in 2025, which added 12 microphones and a new QN3 chip. The XM4 went out of stock and was discontinued in 2025. The XM4C fills the gap left by that compact design, even though its core processing hardware is now three generations old.
Why this matters for you
For buyers, the XM4C sits between Sony's discounted WH-1000XM5, now $200, and its flagship WH-1000XM6, priced around $400. Anyone who prioritizes a compact folding design over the newest chipset gains a cheaper option. For builders and wearable-hardware watchers, the release shows that older audio processing chips still satisfy buyers, a data point relevant to smart glasses and AR audio components. For Sony, reviving a paused product line recaptures demand without funding new research and development.
The bigger question
If a six-year-old audio chip still satisfies buyers today, how much further can wearable hardware improve before returns diminish? The same question applies to smart glasses and AR devices, which also rely on compact processors, batteries, and microphones. Which strategy serves users better, faster annual refresh cycles, or dependable designs brought back at a lower price?
What to watch
The WH-1000XM4C, along with the WH-CH730N and WH-CH530, are set to arrive later this fall of 2026, according to The Verge. Sony's Hello Kitty bundle, featuring the WH-1000XM6, WH-CH730N, or WH-CH530, will be available in limited supply later this year on Sony's website. A full review of the XM4C is expected soon.
