Bose QuietComfort Ultra 2nd Gen — Flagship Wireless Noise-Cancelling Headphones

The Bose QuietComfort Ultra 2nd Gen Black is the brand's flagship over-ear wireless headphone, engineered for listeners who want the strongest noise cancellation the manufacturer has shipped in a portable design. Active noise cancellation adapts in real time to your surroundings, while Bose Immersive Audio spatializes the soundstage for a more cinematic feel. A closed-back circumaural fit seals out external noise and keeps your music private in shared spaces. It excels on a packed commuter train, in a busy open-plan office, or during a long-haul flight.

What Sets the 2nd Generation Apart

CustomTune technology runs a personalized calibration every time you put the headphones on, tailoring the frequency curve to your ear canal's acoustic response. The new Cinema Mode spatializes video content with dialogue-forward sound for a home-theater-like experience on the go. ActiveSense reacts dynamically to sudden loud spikes — like a passing siren or a coffee grinder — and softens them without fully blocking your awareness of the environment.

Connectivity, Battery, and Build — Tuned for Daily Use

Bluetooth 5.4 with A2DP, HFP, and AVRCP profiles handles streaming, hands-free calling, and remote control of your source device. Battery life reaches up to 28 hours per charge in standard listening modes, and a quick 15-minute top-up delivers several extra hours for last-minute departures. The package ships with a hard carrying case, a 3.5 mm to 2.5 mm audio cable for wired passive listening, and a USB-C cable that also enables 16-bit / 44.1–48 kHz lossless digital audio from compatible sources.
