What changed in the second generation?
Bose QuietComfort Ultra Headphones 2nd Gen updates the flagship over-ear line with longer battery life, USB-C digital audio, revised adaptive noise cancellation and Cinema Mode. It remains aimed at travel and daily listening, with a folding design, carry case and approximately 264 g headphone weight.
- Adjustable ANC with Quiet Mode, Aware Mode and ActiveSense.
- Up to 30 hours with ANC, 23 hours with Immersive Audio, or 45 hours with ANC off.
- Bluetooth 5.4 and Bose app support.
- USB-C digital audio at 16-bit/44.1 or 48 kHz.
- Included 3.5 mm-to-2.5 mm analogue cable.
Battery and wired listening
Bose specifies a three-hour full charge and around three hours of playback from a 15-minute quick charge. USB-C can carry audio as well as charge the headphones, while the analogue cable provides compatibility with traditional headphone outputs.
Noise control and Immersive Audio
Quiet Mode applies full noise cancellation, while Aware Mode lets surrounding sound through. ActiveSense can automatically adjust cancellation when sudden environmental noise appears. Bose Immersive Audio adds spatial processing, but it lowers the official battery rating compared with standard ANC playback.
Who should consider it?
This model is best suited to frequent travelers and commuters who value strong noise control, a relatively light fit and both USB-C and analogue wired options. Buyers prioritizing maximum battery life or advanced Bluetooth codecs should compare rivals.
Alternatives
- Sony WH-1000XM6 — compare for LDAC, LC3 and multipoint support.
- Apple AirPods Max — compare for Apple Spatial Audio integration.
- Sennheiser Momentum 4 Wireless — compare for its 60-hour rating.
Final verdict
QuietComfort Ultra Headphones 2nd Gen offers a travel-focused mix of adjustable ANC, USB-C audio, analogue fallback and improved battery life. The central trade-offs are premium pricing, reduced battery with Immersive Audio and USB audio limited to standard 16-bit sample rates.

Who should buy the Bose QuietComfort Ultra Headphones 2?

Frequent flyers, office users and commuters who place long-session comfort and adaptive ANC above codec experimentation or the lowest possible price.
