Sony WF-1000XM6 earbuds leak shows USB-C lossless audio, 40-hour battery, and $329 September US launch
Sony announced the WF-1000XM6, its new flagship true wireless noise-cancelling earbuds, set to launch in the U.S. in September with a $329 price tag. According to leaked specifications, the earbuds feature USB-C lossless audio support and a 40-hour battery life, aiming to improve on previous models in sound quality and noise cancellation.
The Sony WF-1000XM6 earbuds are the latest addition to Sony’s 1000X series of high-end true wireless noise-cancelling headphones, succeeding the WF-1000XM5 released earlier in 2023. Positioned as a flagship model, the WF-1000XM6 aim to compete with other premium ANC earbuds such as Apple’s AirPods Pro. Official listings from European retailers and Sony’s regional websites confirm that the earbuds are already available in markets including Germany and Austria, though Sony has not officially announced U.S. pricing or a September launch date.
Battery performance for the WF-1000XM6 is rated at up to eight hours of playback per charge with ANC enabled and up to 12 hours with ANC disabled, according to Sony and multiple independent tests.
The earbuds weigh approximately 6.5 grams each and come with multiple sizes of in-ear silicone tips designed for passive noise isolation combined with active noise cancellation (ANC). The charging case weighs about 47 grams and features a compact clamshell design suitable for pocket storage. Sony rates the earbuds with an IPX4 water resistance certification, protecting them against splashes from any direction, which reviewers have noted is adequate for sweat and light rain. The shape and ergonomics have been slightly revised from previous models to enhance comfort during extended listening sessions while maintaining a secure fit.
Connectivity is provided via Bluetooth 5.3, supporting the SBC, AAC, LDAC, and LC3 audio codecs, but notably excluding aptX. Reviewers have highlighted the inclusion of LC3 and Auracast broadcast audio features, which depend on compatible smartphones and software. The charging case includes a USB-C port and supports Qi wireless charging, allowing users to recharge the earbuds via cable or wireless charging pads. However, publicly available specifications and official Sony documentation do not confirm support for USB-C lossless audio playback through a wired connection, despite some leaks suggesting otherwise.
Including the additional charges provided by the case, total battery life is approximately 24 hours. This figure is consistent with previous models and has been corroborated by lab tests such as those conducted by ComputerBase, which measured about eight hours and 33 minutes with ANC on and nearly 12 hours and 45 minutes with ANC off at medium volume. The earbuds also support a fast-charge feature, providing roughly 60 minutes of listening time after three to five minutes of charging.
Sony has equipped the WF-1000XM6 with an updated ANC processor and increased the number of microphones to four per earbud—two outward-facing and two inward-facing—to enhance noise cancellation and voice pickup. Reviews consistently describe the ANC performance as among the best available in true wireless in-ear models. The earbuds also offer a natural ambient sound mode that allows users to hear outside noise for conversations and situational awareness. Sound quality has been characterized as balanced and detailed, with clear mids and controlled bass, especially when using the LDAC codec with high-quality audio sources. Call quality has improved over previous generations due to better voice isolation and microphone technology.
Smart features include multipoint Bluetooth support, enabling simultaneous connections to two devices with automatic switching managed via Sony’s Headphones app. The earbuds also incorporate adaptive sound control, which adjusts ANC and ambient sound levels based on user activity and location patterns. An Auto-Switch function coordinates playback between the WF-1000XM6 and compatible Sony LinkBuds speakers, automatically shifting audio when the earbuds are worn or removed. Auracast broadcast audio support is included via Bluetooth 5.3, though full app-level integration depends on the source device.
Pricing information from European retailers lists the WF-1000XM6 in the range of approximately €275 to €300, placing them firmly in the premium category. While some leaks have suggested a U.S. price of $329 and a September launch date, no official Sony announcements or documentation confirm these details. Additionally, claims of a 40-hour total battery life and USB-C lossless audio support have not been substantiated by official specifications or independent testing, which consistently report a 24-hour battery life and no wired USB-C audio playback capability.
The WF-1000XM6 continue Sony’s evolution of the 1000X series, building on previous models with improved noise cancellation, sound quality, and smart features. With availability confirmed in select European markets, further announcements regarding U.S. release and pricing are anticipated but have not yet been made public.
