FollowingGossipAfter that, there is now a more direct official video to introduce the new features of Sony’s unpublished WF-1000XM4 in-ear headphones.Of course, this is obviously not what Sony is willing to release, and the original version on YouTube has also been removed, but A copy of the movie is backed up on Reddit, So we still get a glimpse of its complete content.
In the video, Sony said that the WF-1000XM4 is equipped with a newly designed monomer to improve the sound quality, plus V1 processor, LDAC Bluetooth encoding, DSEE Extreme upscaling, 360 Reality Audio and other technologies, of course, it is also Hi-Res Audio certified. . One of the previously leaked messages that didn’t add much ink to the feature is Sony’s “Speak-to-chat” mode, which can automatically mute the music when it detects that you are speaking.
Other specifications are consistent with the previous gossip, including IPX4 waterproof and Qi wireless charging. When the active noise reduction is turned on, WF-1000XM4 claims to have 8 hours of continuous use, and after it is turned off, it can last up to 12 hours. With the addition of the charging carrying case, the total playback time can reach 36 hours, and it can be used for an hour after 5 minutes of charging in an emergency.
Of course, this kind of video will not include price or time to market information, but I think it shouldn’t be too long. For reference, WF-1000XM3 was priced at US$230 when it was launched.
