Sony WF-1000XM6 Leak: AI-Powered DSEE Ultimate and Early 2026 Release Date Revealed

New details have emerged about Sony's next-generation flagship noise-canceling earbuds, the WF-1000XM6. According to a report from The Walkman Blog on October 14, the earbuds, identified by the model number YY2985, have been approved by the U.S. Federal Communications Commission (FCC). This filing suggests the WF-1000XM6 could be the first Sony true wireless earbuds to feature the advanced DSEE Ultimate audio upscaling technology.

The short-term confidentiality period for the certification documents extends until March 31, 2026. However, by referencing the release schedule of the previous model, the WF-1000XM5, which launched about a month before its confidentiality expired, the media outlet predicts the WF-1000XM6 could be officially unveiled as early as late January or early February 2026.

Based on the limited information from the FCC, the WF-1000XM6 will maintain a circular design similar to its predecessor. One minor change is the relocation of the FCC ID marking from the charging case to the packaging. The earbuds will continue to use a 3.85V internal battery, though the specific capacity has not been disclosed. The antenna retains the same monopole design as the WF-1000XM5 but features a slight gain adjustment from -3 dBi to -2.5 dBi, which may improve connection stability.

The most significant revelation from this leak is the upgrade to the core chipset. Test documents show that the WF-1000XM6 uses the same testing software as Sony's LinkBuds series, leading to speculation that it will be powered by MediaTek's new MT2855 system-on-chip (SoC). The documents also confirm that the antenna and System-in-Package (SiP) will continue to be manufactured by Goertek Inc.

Thanks to the powerful processing capabilities of this new chip, the WF-1000XM6 is expected to be the first Sony true wireless earbuds to support DSEE Ultimate. This exclusive Sony audio enhancement technology utilizes Edge-AI to upscale compressed digital music files in real-time. It can even optimize CD-quality lossless audio, restoring subtle sound details and expanding the dynamic range to deliver a richer, more complete listening experience.
