Bose QuietComfort Ultra Earbuds (2nd Gen) - Premium Noise Cancelling

In this review of the QuietComfort Ultra Earbuds (2nd Gen) the bottom line is simple: these earbuds are for listeners who want the best in-ear noise cancellation and personalised sound in a compact, daily-wear package. The standout reason to buy is the combination of world-class noise cancellation and CustomTune audio that adapts to your ear shape, delivering immersive sound and reliable call clarity whether commuting, working, or relaxing at home.

Key Features

• ActiveSense noise control: Smooths sudden spikes in surrounding sound so Quiet Mode stays consistently effective without harsh transitions.
• CustomTune technology: Analyses ear fit and adjusts both noise cancelling and audio for a tailored listening profile on every use.
• Multiple listening modes: Quiet, Aware, and Immersion Modes let users choose full cancellation, maximum transparency, or spatialised audio for media.
• Secure fit options: Nine eartip and stability band combinations provide a snug seal that improves noise isolation and all-day comfort.
• Clear call performance: SpeechClarity mics reduce background noise and wind so voices come through clearly on calls.
• Charging convenience: A wireless charging case plus USB-C support offers up to six hours per charge and multiple full recharges from the case.

Who It's For

These earbuds suit commuters, frequent travelers, and anyone who prioritises noise cancellation and personalised sound. The combination of immersive audio and Cinema Mode is also useful for viewers who want a wider soundstage for video and streaming on phones or tablets.

Those who need the simplest, most budget-friendly earbuds or who require extreme water resistance should look elsewhere, since these are targeted at premium audio performance with an IPX4 rating for sweat and light splashes rather than heavy water exposure.
