Here are the first photos of Sony wh-1000xm4 wireless headset.The company's previously acclaimed wh-1000xm3 wireless headset is popular for its excellent noise reduction, comfort and battery life.

The spy photos of Sony wh-1000xm4 were initially found by Everton favretto in the manual released by FCC Anatel in Brazil, which helps to explain the lack of artistry of spy photos. The most amazing thing is that the appearance of Sony wh-1000xm4 is very similar to that of current Sony wh-1000xm3.

However, according to the draft manual, the following is the improvement of Sony wh-1000xm4 on Sony wh-1000xm3. It supports Bluetooth V5 (updated from v4.2), 2W rated power consumption (less than 8W), can run for 40 hours when connected through headphone cable, and can eliminate noise for 36 hours at most. It has a new function called "talk chat", which may enable it to communicate with Google Assistant, Siri and Alexa work together more easily.

Bluetooth 5 and lower power consumption should allow Sony wh-1000xm4 to run in wireless mode for a longer time, and Sony wh-1000xm4 may continue to maintain the price tag of $349.99.
