Review on Sony WF-1000XM3 Black Truly Wireless Earbuds with Mic, up to 32 Hours Battery Life, Stable Bluetooth Connection, Wearing Detection and Alexa Built-in for Noise Cancelling by Velizar Botev ᠌

No indication of the severity of the charges. White noise is muted or played at very low volumes when noise cancellation is on. The left earbud is in charge and can function independently from the right. This is a major drawback. Separately, I'd want to point out that using the headset to communicate is a major pain. You hear your conversation partner as if in a shell, and he hears you as if via a pipe. The noise reduction is functional, but subpar. Adaptive noise reduction is dishonest; it will only make a change if it feels like it. There is little practical use for translating environments.
