Sony launches WH-1000XM4C with enhanced audio profile and lower price
Developed over time first seen 2 months ago
Sony is reviving its acclaimed WH-1000XM4 headphones as the WH-1000XM4C, alongside two new budget models, rather than releasing an entirely new upper-midrange headset. The XM4C keeps the original's design and features, including QN1-chip noise cancellation and multipoint Bluetooth, but adds Sony's newer sound profile, 10-band and gaming EQs, and Quick Access streaming shortcuts. This unusual "re-release" strategy lets Sony offer a proven, well-reviewed model at a lower price than its current flagship, the WH-1000XM6, while filling out the rest of its headphone range with fresh mid-range and budget entries.
The WH-1000XM4C will cost $300 when it launches this autumn, $50 less than the original XM4 and $150 cheaper than the XM6, though battery life drops to 27 hours with noise cancellation on, three hours less than before, offset by a faster quick-charge feature giving an hour of playback from three minutes' charging. Sony is also launching the WH-CH730N, a $180 replacement for the WH-CH720N with a redesigned folding build, improved ANC and call quality, and battery life of up to 50 hours with noise cancellation on; and the WH-CH530, a $70 successor to the WH-CH520 with no ANC but better sound, AI-assisted calls and 55 hours of battery life. Both new models also add safe-listening features to manage volume and usage over time, and all three headphones are due out this September.

Full account
Sony has revived one of its most acclaimed headphone models, relaunching the 2020-era WH-1000XM4 as the WH-1000XM4C rather than developing an entirely new upper-mid-range design. The original XM4 was praised for years for its sound quality, noise cancellation and compact folding shape before going out of production, and the new C variant brings it back largely unchanged, alongside two refreshed budget and mid-range models, the WH-CH730N and WH-CH530, due out this autumn.
Visually and mechanically, the XM4C is essentially identical to its predecessor, retaining the same folding hinge design that Sony had moved away from with the larger WH-1000XM5 in 2022 before partially returning to it with last year's XM6. The headphones keep the ageing QN1 processing chip and four-microphone array used for active noise cancellation, hardware that has since been superseded twice over: the XM5 paired the same QN1 chip with eight microphones, while the XM6 uses a newer QN3 chip with twelve. The one cosmetic change is the addition of a lavender colourway alongside the existing black and white options.
Sony has, however, updated the software side of the headphones. The XM4C gains the sound profile used across its current range, a 10-band equaliser in place of the original's 5-band version, a new gaming EQ preset, and support for Bluetooth 6 rather than Bluetooth 5. Battery life has actually dipped slightly, with Sony quoting up to 27 hours of use with noise cancellation switched on, down from 30 hours on the original model, though this is offset somewhat by a faster quick-charge function. At £/$300, the XM4C undercuts the original XM4's 2020 launch price by $50 and comes in cheaper than the current XM6, positioning it as a budget route back into Sony's flagship noise-cancelling line.
Launching alongside the XM4C are two lower-tier updates. The WH-CH730N replaces the WH-CH720N with a redesigned, now-foldable headband, a claimed 10 percent reduction in ambient noise, AI-assisted call quality improvements, the same EQ upgrades as the XM4C, and substantially longer battery life, priced at $180. The more affordable WH-CH530 also receives the new 10-band and gaming EQ features, though further details of that model were not fully covered in the available reporting.
Where outlets differ
From the full account, which is AI-written from the sources:
The two reports give different figures for how much cheaper the XM4C is than the WH-1000XM6: one puts the saving at roughly $100, the other at $150, suggesting they may be comparing against different reference prices for the XM6.
One outlet frames the relaunch with notable scepticism, with its reviewer questioning why Sony would revive six-year-old hardware when the newer XM5 is currently available near a similar price, while the other report treats the launch more matter-of-factly as a straightforward product refresh.
Battery-life reporting differs slightly in detail: one source only cites the ANC-on figure (30 hours down to 27), while the other also specifies a four-hour reduction with ANC switched off and highlights a faster quick-charge feature (roughly one hour of playback from a three-minute charge) not mentioned elsewhere.
Coverage of the two lower-tier models is uneven: one report describes the WH-CH730N in detail, including its redesigned housing, noise reduction claims and battery gains, while the other only briefly notes shared EQ features across both new budget models, with limited detail on the entry-level WH-CH530.
Explained simply
Sony's WH-1000XM4 was one of the most highly rated wireless headphones on the market when it first launched, praised for its noise cancellation and sound quality. Instead of retiring it, Sony is reissuing it as the WH-1000XM4C, keeping the same design and core technology but adding some newer software features. This sits alongside Sony's current top model, the WH-1000XM6, giving buyers a cheaper option that still carries the well-regarded XM4 reputation.
Sony is also introducing two lower-cost headphone models aimed at buyers who don't need flagship features, replacing older budget models in its range with updated versions offering longer battery life and other improvements. Together, the three headphones cover different price points, from premium to entry-level.
This matters because it marks an unusual approach for a major electronics maker, choosing to relaunch a proven older product rather than only pushing customers towards newer, pricier releases, in a wireless headphone market where Sony competes closely with rivals such as Bose and Apple.
