This week on the Internet there has been detailed information on new fully wireless submersible type Sony WF-1000XM4 type, which must be officially represented soon. Now this data confirmed the official video Sony, which for some reason it appeared on YouTube for some reason, but soon it was removed. Fortunately, one of the users of the Reddit community managed to copy it.
The video says that new headphones provide higher sound quality, as well as support LDAC codec, which makes it possible to play high-resolution sources. The device supports DSEE EXTREME technology, which, according to Sony, makes compressed audio files with better and more alive. Headphones are capable of playing the sound of Hi-Res Audio and are equipped with a system of active noise cancellation (ANC).
One of the features that was not known before the appearance of the video mentioned earlier is the presence of a SPEAK-TO-CHAT brand mode, in which the audio audio mode is automatically disabled if the headphones define that the user is talking to someone. Video also confirms many features of the WF-1000XM4, which were previously reported. It is underlined by water resistance of the device (protection according to IPX4 standard), as well as support for wireless charging technology Qi. It is argued that the user will receive up to 8 hours of autonomous operation WF-1000XM4 with an activated ANC mode and up to 12 hours without it. Using a complete charging case, you can get up to 36 hours of autonomous work, and only five minutes of charging will be enough to listen to the audio within an hour.
Unfortunately, the video does not say about the timing of the receipt of new Sony headphones in retail sales and their cost. It is assumed that in Europe the WF-1000XM4 will cost € 280, while WF-1000XM3, the model of the previous generation, at the time of launch was sold for $ 230.
