Bose QuietComfort Ultra Wireless Noise Cancelling Headphones, Spatial Audio, Over-the-Ear Headphones with Mic, 24H Battery Life, 2023, White Smoke

Bose describes the microphone system on this model as delivering the clearest calls of any headphone it has made. Bose QuietComfort Ultra White Smoke uses a dedicated noise-rejecting array that locks onto your voice and discards the room around it, which is the specification that matters if you work from cafes, airports or an open-plan office.

QuietComfort Ultra White Smoke: Microphones That Only Want Your Voice

The microphones that handle noise cancellation and the microphones that carry your voice are doing opposite jobs. One set has to hear the room accurately. The other has to ignore it completely.

Bose separates them, giving the call path its own noise-rejecting array that isolates speech from the background before transmitting. The person on the other end hears you, not the coffee machine, which is a very different outcome from headphones that simply reuse the cancellation microphones for calls.

Bose QuietComfort Ultra White Smoke on a Call

Use Aware Mode while you are speaking. Full cancellation removes your own voice from your ears as well as the room, and the reliable result is that people talk far too loudly without realising it. Aware Mode restores natural self-monitoring.

For a noisy space, a saved custom mode at partial cancellation is usually the better compromise: enough isolation to concentrate between calls, enough awareness to hear yourself and anyone approaching your desk.

QuietComfort Ultra White Smoke: Bluetooth 5.3 and aptX Adaptive

Connection runs on Bluetooth 5.3 with a working range of about 9 metres, which covers walking to the kitchen without your call breaking up. On compatible Android devices the headphones also support aptX Adaptive, a codec that carries more data than standard SBC and adjusts bitrate as signal strength changes.

iPhone users fall back to AAC, which remains perfectly capable — the advantage simply does not apply. Full specifications are on the official Bose QuietComfort Ultra Headphones page.

QuietComfort Ultra White Smoke: Who White Smoke Suits

White Smoke is a soft off-white with a faint grey cast rather than a bright white, so it does not glare on camera under a ring light or office ceiling panel. For anyone whose headphones appear in video calls several times a day, that is a real consideration rather than a cosmetic one.

The upkeep is the same as any pale finish: the protein leather cushions pick up marks from skin and hair products faster than dark colours, and a wipe every couple of weeks keeps them looking new. Black asks nothing and sounds identical.

QuietComfort Ultra White Smoke: Two Battery Numbers, Not One

Bose quotes up to 24 hours with Immersive Audio off and up to 18 hours with it on. If your day is mostly calls and podcasts, spatial audio adds little and you live at the higher figure. If you use Immersion Mode for music and film, plan for the lower one.

A full charge takes roughly three hours over USB-C, and fifteen minutes on the cable between meetings returns around two and a half hours of use.
