Bose QuietComfort 45 vs Sony WH-1000XM4
The Verdict
Both headphones deliver exceptional noise cancellation, but they excel in different areas. Bose QuietComfort 45 offers 24-hour battery life with a lighter 240g frame, plus the convenient 15-minute quick charge that delivers 3 hours of playback. Sony WH-1000XM4 counters with superior 30-hour battery endurance and a faster 10-minute charge yielding 5 hours of use. Sound quality differs meaningfully: Sony supports LDAC hi-res wireless audio alongside aptX codecs, enabling higher bitrate streaming for audiophiles, while Bose sticks with standard SBC and AAC. Sony's Dual Noise Sensor ANC technology and DSEE Extreme upscaling provide more refined noise cancellation and audio enhancement. Bose compensates with adjustable EQ customization via its app and Aware mode transparency feature. Both include multipoint connection and are similarly priced at $329 versus $349. If battery longevity and hi-res audio matter most, Sony wins decisively. For those prioritizing lightweight comfort, quick charging flexibility, and EQ tweaking, Bose remains competitive. Sony's technical advantages in ANC sophistication and codec support make it the stronger all-around choice for serious listeners.
