Leaked Sony WH-1000XM4 headphones promo video reveals wearing detection feature and handy Speak-to-Chat mode

Sony is holding an audio-related event on August 6 and it is widely believed that this is when the much-heralded Sony WH-1000XM4 ANC headphones will be officially launched. Various leaks concerning the headphones have already revealed some details, including an expectedly hefty price tag. But with the WH-1000XM4 headphones you do seem to be getting what you pay for, as a leaked promo video has unveiled many of the features the device will boast of (see below to watch the clip).

For instance, the Sony WH-1000XM4 headphones have a wearing detection sensor, which means they will stop playing audio if you remove them from your head. There is also a useful Speak-to-Chat mode where audio is paused if you start talking to someone while wearing the headphones. The audio is paused for a default period of 30 seconds, although this can be altered in the accompanying app. The WH-1000XM4 headphones are fitted with a QN1 processor, Bluetooth audio SoC, 40 mm HD hybrid drivers and they feature touch controls.

The list of features doesn’t stop there though. The Sony WH-1000XM4 headphones have adaptive sound control depending on your activity and location (walking, sitting on a train, etc.) and you can program the device to play your favorite sounds in certain registered places. Hands-free calling is onboard, as is the use of Google Assistant or Amazon Alexa where available. Users can expect to enjoy 360-degree reality audio that is enhanced by the DSEE Extreme engine, which offers real time audio up-scaling based on the music genre or instrument type.

The Sony WH-1000XM4 personal audio device, which is shown both in black and silver-gray, has dual noise sensor technology to help provide the best sound possible for buyers of the premium ANC headphones, and up to 30 hours of playback can also be expected. With fast-charge technology, the Sony headphones can get a quick 10-minute power boost and last five hours just from that. It’s a lot of technology built into a pair of headphones, but you would expect that from a device that is rumored to be priced in the region of US$349/€379.90.
