Review on 🎧 Sony WH-1000XM4 Noise-Canceling Wireless Headphones with Alexa & Mic, Blue by Kai Shift ᠌

My text today is about my use of the product Sony WH 1000XM4 Canceling Headphones Phone Call. While the headphones are turned on, and no audio is playing, the left and right channels are unbalanced in terms of noise reduction - the level of background noise in the left earphone is noticeably stronger than in the right one. With a high level of external noise and when playing audio, the effect is not noticeable.
