Freedom perfected in a truly wireless design, with industry-leading noise-canceling powered by Sony’s proprietary HD Noise Canceling Processor QN1e. Form meets function with up to 24 total hours of battery life. The noise-canceling technology in the WF-1000XM3 is the most advanced ever in truly wireless earbuds, with our HD Noise-Canceling Processor QN1e. So you can lose yourself completely in your music. Dual microphones—one feed-forward and one feed-back—on the surface of the earbuds catch more of the ambient sounds from your surroundings, whether it’s in-flight noise, city traffic, or office chatter. Having caught the ambient sound, the dedicated HD Noise-Canceling Processor QN1e gets to work. It not only cancels significantly more noise across almost all frequencies but also uses less power. Packed with advanced audio technology, the WF-1000XM3 noise-canceling earbuds not only deliver noise-free listening but also offer breathtaking sound quality. Digital Sound Enhancement Engine HX (DSEE HX) up scales compressed digital music files, bringing them closer to the quality of High-Resolution Audio. Watching video content on your smartphone or tablet? The advanced wireless connection on the WF-1000XM3 syncs what you see on screen precisely with what you hear on your earbuds for more enjoyable viewing. A Bluetooth chip, which transmits sound to left and right ears simultaneously, coupled with optimized antenna design ensures a stable connection and outstanding listening. Low audio latency makes for enjoyable viewing too. On a full charge, the earbuds offer 6 hours of power, and the handy charging case provides a further three charges to keep you going throughout the day. That’s up to 24 hours of noise-free listening. With noise canceling off, it’s even longer — 8 hours of power on a full charge, with a further three charges from the charging case, for up to 32 hours of play time.
