Bose QuietComfort 45 vs Bose QuietComfort Headphones
The Verdict
Both Bose over-ear headphones deliver excellent active noise cancellation and 24-hour battery life, but they diverge in refinement and features. QuietComfort 45 weighs 240g versus 296g for the newer model, offering superior comfort during extended wear. QuietComfort Headphones introduces CustomTune personalized audio calibration and Bluetooth 5.3 for more stable connections, plus faster charging at 2.5 hours complete versus the 45's longer charge time. Fast-charge capability favors the 45 with 15 minutes yielding 3 hours playback compared to 2.5 hours on the newer model. Sound quality remains impressive across both, though CustomTune optimization on the QuietComfort Headphones provides personalized audio tuning. Battery life matches at 24 hours with ANC enabled. For listeners prioritizing comfort and quick top-ups, QuietComfort 45 edges ahead despite being $20 cheaper. Those wanting advanced personalization and latest Bluetooth technology should consider the newer QuietComfort Headphones. Choose based on comfort priority versus feature preference.
