Sony’s next flagship earbuds, the Sony WF-1000XM6, are drawing attention for more than just sound quality. A recent teardown based on FCC filings suggests Sony has quietly made the new model easier to repair, particularly when it comes to battery replacement.
That may not sound flashy, but for long-term owners of these expensive earbuds, it’s a big deal.
The analysis, published by The Walkman Blog, pulls from internal photos and schematics included in US FCC documentation. One key change stands out: Sony has removed the ribbon cable that previously connected the top cover to the main internal components.
Why does that matter? Ribbon cables are fragile. During disassembly, especially when trying to replace aging batteries, they’re easy to tear. Removing that component simplifies the process and reduces the risk of accidental damage. For a product category often criticized for being difficult to repair, that’s a meaningful step.
Inside the earbuds
Internal photos reveal Bluetooth antenna contacts, touch sensor connectors, microphone openings, and a MEMS mic mounted directly on the board. There’s also a transparent plastic layer on top, a small design touch that visually separates this generation from earlier leaks.
The battery is listed as model Z55FA, rated at 3.85V. Multiple suppliers are mentioned, including Springpower, Highpower (TH), VDL, and Zhuhai ZeniPower Battery Co., Ltd., with signs pointing to ZeniPower as a primary source. Capacity isn’t disclosed in the FCC paperwork.
On the silicon side, the teardown confirms an updated system-in-package module labeled GSBR-005 (version 3-2), integrating an MT2833 Bluetooth chip. Although resin coating obscures some details, component sizing suggests the new QN3e noise-canceling chip is noticeably larger than the previous QN2e.
Sony’s XM series has long been considered among the best in the noise-canceling true wireless category. By improving internal design for easier servicing, without compromising premium hardware, Sony seems to be addressing one of the biggest long-term pain points in wireless earbuds: battery degradation.
Of course, real-world performance will ultimately decide how compelling the upgrade is. But on paper, the WF-1000XM6 look like a refinement in more ways than one. It’s already available for $329.99 on Sony’s US website.
