Regardless of which Sony product you purchase, you can always expect them to deliver top-notch audio quality and leading active noise cancellation, making your audio experience the best ever. Both audio devices also tout impressive battery life for their respective classes along with features that allow you to multi-task while listening to music, your favorite TV show, or a movie. For instance, if you have an incoming call, the Sony WH-1000XM4 or WF-1000XM4 will automatically reduce the volume when you are having a conversation with the other person.
