I used on and off this for 2 weeks before I realized that I don’t like noise-cancelling headphones! I also work in an environment where I am constantly in meetings so I don’t really have a need for this! Here’s a full description: Beats and Apple are changing the way you listen to music with the Apple W1 chip in Beats Studio3 Wireless headphones. Incorporating the efficient W1 chip brings seamless setup and switching for your Apple devices*, up to 22 hours of battery life for all-day full-featured playback with Pure ANC on, and Fast Fuel technology for 3 hours of play with a 10-minute charge. Pure ANC-off for low power mode provides up to 40 hours of battery life.
