by Sony has introduced the new WH-1000XM4 full-size wireless headphones. The model is based on 40mm dome-type speakers with CCAW voice coil. The range of reproducible frequencies is from 4 to 40,000 Hz.
The WH-1000XM4 is supported by Sony Edge-AI proprietary artificial intelligence technology. It allows you to recover parts of audio lost during digital compression. There is also Dual Noise Sensor active noise canceling technology. It picks up ambient noise using four microphones on the ear cups and transmits the data to the QN1 HD processor, which performs noise cancellation in real time based on the acoustic characteristics of the environment.
The processor evaluates the parameters of music and noise at a frequency of 700 times per second. Plus, the headphones use a range of smart technologies to enable hands-free listening. For example, just start talking and Speak-to-Chat will automatically pause playback. And this week Samsung introduced the Galaxy Buds Live Wireless Bean Headphones.
