The details of the SONY WF-1000XM4 continue to be exposed. This time, the promotional video of this headset is directly exposed. Although the original version has been removed from YouTube, enthusiastic netizens have left a backup on Reddit. Friends who are interested in the released headset may wish to check it out.
In the film, SONY WF-1000XM4 is equipped with a newly designed monomer to improve the sound quality, plus a 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 did not explain much is the “Speak-to-chat” mode, which can automatically mute the music when it detects that you are speaking.
Other specifications are consistent with the previous news, 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 believe it is not far from being released. WF-1000XM3 was priced at RM949 when it was launched. The next price of SONY WF-1000XM4 is very worth looking forward to.
