Bose QuietComfort Ultra 2nd Gen
ActiveSense adaptive noise canceling and CustomTune personalization define the Bose QuietComfort Ultra 2nd Gen, providing 6-hour earbud battery life, a 20-minute quick charge for 2 hours, and 24-hour total with the Qi case. The spatial audio with Immersion mode delivers head-tracked 3D sound, while the 7-gram design and IPX4 splash resistance keep them comfortable for daily wear. These are best for frequent travelers and commuters who demand adaptive ANC and immersive audio, rather than those needing sweatproof earbuds for intense workouts.
