Bose has refreshed its QuietComfort Ultra lineup with a second-generation model that keeps the familiar QuietComfort silhouette while introducing several meaningful internal upgrades. The QC Ultra (2nd Gen) preserves the classic soft-cushioned earcups and lightweight profile, but adds a sleeker polished finish on the headband bar and a slightly more refined aesthetic. More important than the cosmetics are the audio and software improvements: lossless USB-C playback, a new Cinema audio profile, upgraded adaptive ANC, and modern wireless features such as Bluetooth 5.4.
Key features
Design and comfort
The exterior remains comfortably recognizable — synthetic leather pads and plastic earcups deliver the low weight QuietComfort users expect. The updated finish gives it a premium touch without sacrificing long-session comfort and durability.
Audio upgrades: lossless USB-C and wired options
One of the headline additions is native lossless USB-C audio support, which enables low-latency, high-resolution sound when connected to a compatible source. Bose bundles both 2.5mm and 3.5mm cables for wired listening, making the headphones flexible for studio work, travel, or hi-res playback.

Noise cancellation and Aware Mode
ANC receives a software-focused boost: a new adaptive noise control algorithm smooths its reaction to abrupt environmental noises such as sirens or passing trains. Aware Mode has been retooled to blend ambient sound more naturally without interrupting playback. Users can fully disable active noise cancellation or fine-tune levels inside the Bose app.
Cinema Mode and immersive audio
Bose introduces a Cinema audio profile designed to expand the soundstage, emphasize dialogue, and add spatial effects for film and TV. The profile also improves spoken-word content like podcasts and audiobooks, making dialogue clearer and more forward in the mix.
Connectivity, codecs and battery
Wireless connectivity is modern: Bluetooth 5.4 with multipoint pairing, support for AAC, SBC and aptX Adaptive for Snapdragon Sound-certified devices, plus Google Fast Pair and Spotify Tap. Battery life ranges up to 30 hours in typical use, about 23 hours with immersive audio active, and up to 45 hours with ANC off.
Comparisons and advantages
Compared with the original QC Ultra, the 2nd Gen focuses on sound fidelity and adaptive processing rather than a radical redesign. Lossless USB-C is a standout advantage for listeners who prioritize wired, high-resolution audio. Improved adaptive ANC and Cinema Mode make the headset a stronger all-rounder for commuting, office work, and home entertainment versus its predecessor and many rivals in the premium ANC market.
Use cases
- Commuters and frequent travelers who need reliable ANC and long battery life.
- Home theater and streaming enthusiasts using Cinema Mode for a wider soundstage.
- Podcasts and audiobooks listeners who want clearer dialogue and spatial clarity.
- Professionals who require low-latency USB-C audio for editing or high-res playback.
Price and market relevance
The Bose QuietComfort Ultra Headphones (2nd Gen) are priced at $450 / £450 and are available in Black, White Smoke, plus two limited editions: Driftwood Sand and Midnight Violet. With its mix of lossless USB-C support, advanced ANC, and modern wireless features, Bose positions the QC Ultra 2nd Gen as a compelling option in the premium headphone segment, targeting listeners who want both fidelity and versatile noise control.
