CMF by Nothing Buds 2 wireless earbuds

If you want earbuds for commuting, workouts, and calls, active noise cancellation and water resistance may matter more than a stripped-down listening setup.

CMF by Nothing Buds 2 bring those features together with an 11mm driver and app controls for sound and ANC.

The trade-off is that the headline 55-hour figure includes the charging case, a single charge is listed for up to 13.5 hours.

How it fits

Hybrid ANC is the main reason to consider these for noisy surroundings. CMF lists noise cancellation up to 48dB across a 5200Hz range, plus an Environmental Adaptive mode that adjusts reduction to the surroundings. That may suit a commute where the noise changes from a steady rumble to a busier platform, though the listing alone can’t show how much noise you’ll notice in your own routine.

For music, the 11mm PMI driver, Dirac Opteo tuning, and Ultra Bass settings point toward a fuller, adjustable sound. A spatial audio effect is also included for movies and games. Do you want one pair to move between a playlist, a video, and a call without changing devices? The feature mix is aimed at that kind of everyday switching.

Calls get six microphones, AI-powered Clear Voice Technology 3.0, and Wind Noise Reduction 3.0. IP55 water and dust resistance adds some reassurance for a sweaty workout or a walk in light rain, but it isn’t a reason to treat the earbuds as waterproof. Bluetooth 5.4 and in-ear detection are listed, the product details don’t specify supported audio codecs.

Pros

• ANC includes an adaptive mode, rather than relying only on a fixed setting.
• The Nothing X app offers EQ, Ultra Bass, ANC controls, and a Low Lag Mode for gaming.
• Battery life is listed at up to 13.5 hours per charge and 55 hours with the case. A 10-minute top-up is listed for up to 7.5 hours of playback.
• Six microphones and wind-noise reduction target clearer calls outdoors.
• IP55 protection makes the earbuds more practical for exercise and occasional rain than an unprotected pair.

It’s a great fit if you want noise control, app-based sound adjustments, and long listed battery life in one set of true wireless earbuds. It may not suit you if you need a particular codec, or want published details about how the ANC performs in specific environments. The battery figures are useful for planning, but keep the distinction between one charge and the case’s total in mind.

Buying verdict

On the spec sheet, Buds 2 cover several daily-use priorities: adjustable ANC, call-focused microphone features, a spatial audio effect, and battery claims that include a quick top-up. The Nothing X app adds useful control if you’re willing to adjust EQ or noise reduction instead of leaving everything at its default.

Compared with choosing a simpler pair for basic playback alone, these make more sense if you’ll use ANC, take calls, or wear earbuds during workouts. Their clearest limitation is the gap between the per-charge figure and the larger case-inclusive total, frequent listeners should weigh both. The supplied details also don’t establish a specific codec or real-world ANC result. Buy them if the listed features match your routine and IP55 protection is enough for your use, look elsewhere if you need confirmed codec support or more detailed performance information.
