The WF-1000XM4 is Sony's flagship true wireless earbud, built around the V1 processor and dual noise-sensing microphones per ear for strong active noise cancellation. Polyurethane foam ear tips seal the canal to block more sound, and Speak-to-Chat pauses music when you start talking. Sound is detailed and bass-rich, with Sony's app for EQ and settings. It suits commuters and frequent flyers who want top-tier ANC in a small package, though its 3.4-star average shows buyers split on fit and reliability against rivals like the AirPods Pro and Bose QuietComfort Earbuds.

Owners praise the noise cancellation and sound quality, calling them among the best in the class. Many complain about fit, foam tip durability and occasional connection or battery issues, which drags the average down.
These Sony truly wireless in-ear earbuds come with a charging case and have noise canceling. Each earbud has two noise sensor microphones on its outer surface: one feed-forward and one feed-back. Together they pick up more ambient noise so it can be blocked out.
A Sony-designed V1 integrated processor handles the noise canceling. It blocks more noise than before while using less power. The earbuds also sense when you start a conversation. They pause the music automatically and resume it when the conversation ends.
The ear tips are made of a soft, elastic polyurethane foam. They are designed to fit closely, eliminating gaps to insulate sound and reduce noise.
