The Bose QuietComfort Ultra Earbuds 2nd Gen deliver up to 6 hours of battery life with the earbuds alone, dropping to around 4 hours when Immersive Audio is active. The charging case provides three additional full charges, giving you approximately 24 hours of total listening time.
Real-World Performance
Independent testing shows actual battery life closer to 5.5 hours per charge. Performance varies based on volume levels, noise cancellation intensity, and feature usage.
Quick Charge Feature
A 20-minute charge provides roughly 2 hours of playback. Full charging takes about 2 hours via USB-C or wireless charging (Qi-compatible).
New in 2nd Gen
Wireless charging support is a welcome addition, making it easier to top up the case on any compatible charging pad.
How It Compares
Battery life falls behind competitors like the Sony WF-1000XM5 (8-9 hours) and AirPods Pro 3 (8+ hours). The QC Ultra Earbuds are best suited for users who don't mind carrying the case for longer listening sessions.
