Get a good look at the features of the Sony WF-1000XM4 in this leaked video
June 17, 2025
The Sony WF-1000XM4 are the most hotly anticipatedtrue wireless earbudsright now. While Sony is yet to announce a launch or release date, multiple leaks have already outed their refreshed, more compactdesignas well as upgradedspecifications. Now, a leaked promotional video spotted onRedditbySparrowsNewsshows the WF-1000XM4 in action, confirming all of its new features.
The video starts by teasing the “industry-leading noise cancellation” of the WF-1000XM4. It also shows that the earbuds will feature Sony’s integrated V1 processor, new drivers for a fuller, richer sound, support for LDAC and Hi-Res Audio, and DSEE EXTREME AI technology to reproduce frequency responses of the original sound source lost during compression.
Further, the leaked video of the WF-1000XM4 shows that it borrows some features from theSony WH-1000XM4wireless headset. For instance, you’ll get the Speak-To-Chat function that automatically pauses playback when you start a conversation. You’ll also get Sony’s Adaptive Sound Control for adjusting ambient sound levels based on your environment.
The WF-1000XM4 will feature bone conduction sensors to detect speech vibrations, Google Assistant and Alexa support, wireless charging, and IPX4 certification for protection against splashes.
The text in the video confirms that the earbuds can function for eight hours at a stretch with ANC switched on. The battery life can further increase to 16 hours with the charging case. So in total, you’re able to get 24 hours of playback with ANC.
With noise-cancelling turned off, you can seemingly get 12 hours of playback from the buds alone and another 24 hours with the charging case. That’s a whopping 36 hours of usage.
Clearly, the new Sony buds are all set to give theAirPods Proa run for their money. They won’t come cheap, though. The previous iteration of the true wireless earbuds launched for $230. With the new design and features, we expect the Sony WF-1000XM4 to launch around $250 or maybe a bit more.
