In this CMF Buds 2 review, we explore why the mid-tier model in Nothing’s latest budget audio lineup might actually be the smarter buy.
A few weeks ago, we examined the CMF Buds 2 Plus, the premium variant. Now, it’s time to take a close look at its sibling, the CMF Buds 2, and see whether the cost savings come with any meaningful compromises.
Price and Value
Priced at $59, £39, or INR 2,699, the CMF Buds 2 sit comfortably between budget and premium. While they do skip a few features found in the Plus model the essentials are still intact. The question becomes whether those missing pieces are truly deal-breakers for the average user.
Design
Visually, the CMF Buds 2 are nearly indistinguishable from the Plus model. The charging case shares the same dimensions, although the finish feels more plasticky compared to the soft-touch texture on the Buds 2 Plus.
One notable difference is the lid’s rotating dial. Unlike the aluminum dial on the Plus, the Buds 2 feature a clear plastic one. Its function remains ornamental unless you find joy in spinning it like a fidget toy.
The earbuds themselves are identical in shape and weight. They offer a comfortable fit and remain lightweight, but the ear tips feel just as cheap as the ones included with the Plus. For a product at this price point, better-fitting tips should have been a given.
They often slide in and out without forming a secure seal, making the listening experience less satisfying.
Other brands, like the OnePlus Nord Buds 3 Pro, offer superior ear tips for the same price, adding extra pressure on CMF to improve this detail in future releases.
Software Experience
The Buds 2 integrate seamlessly with the Nothing X app, the same platform used for other Nothing earbuds. Most features are consistent with the Plus model, so let’s focus on what sets them apart.
First, the Buds 2 come with Dirac Opteo as the default equalizer.
According to Wikipedia, Dirac uses advanced correction technology to optimize acoustic performance. However, detailed technical documentation remains scarce.
Second, this version drops the Personal Sound feature. This was the customizable hearing test available in the Plus model, but its absence here doesn’t feel significant. In fact, many users may prefer a simpler setup.
Third, the Buds 2 do not support LDAC, which means no switching between AAC and high-resolution audio. For those who value simplicity over codec flexibility, this won’t matter much.
Sound Quality
Despite a smaller 11mm driver compared to the Plus model’s 12mm, the Buds 2 deliver an impressive audio experience. The sound is warmer and bassier, with noticeable mid-bass that adds richness. Interestingly, this tuning makes vocals sound bolder and more forward in the mix.
While the Buds 2 lack some of the high-end sparkle found in the Plus, they make up for it with a fuller mid-range. That balance results in a more engaging listening experience, especially for genres like pop and hip hop.
There are multiple EQ presets available in the Nothing X app. However, switching between them introduces a noticeable break in audio and a temporary spike in volume. Only the Opteo and custom presets maintain smooth performance.
The custom preset retains the benefits of Dirac’s processing, making it a worthwhile option for those who want to tweak the sound without losing clarity. That said, Nothing’s 3-band circular EQ remains clunky and unintuitive, something we’ve noted in previous reviews.
Microphone Quality
Voice calls on the Buds 2 are clear, with minimal background noise and only slight modulation during quiet moments. Overall, the microphone quality holds up well in various environments and matches the performance of more expensive options.
Noise Cancellation and Transparency
The Buds 2 offer decent active noise cancellation, especially in low-frequency environments like buses or trains. However, the poor ear tip fit limits high-frequency isolation. For the average commuter, the ANC is good enough, though not industry-leading.
Transparency mode could use some work. The sound comes through naturally, but it’s often too quiet to be helpful, especially when music is playing. This undermines its usefulness in situations where situational awareness is critical.

Battery Life
Nothing claims up to 13.5 hours of playback with ANC turned off. In real-world testing, we achieved 13 hours and 17 minutes. A quick 10-minute charge provided over 4 hours of playback, matching the company’s advertised specs and then some.
These results make the Buds 2 one of the more reliable options for long listening sessions without constant recharging.
Final Verdict
When we first reviewed the Buds 2 Plus, it seemed like the logical recommendation due to its added features. However, after testing the CMF Buds 2, the tables have turned.
The Buds 2 bring nearly everything to the table. Most importantly, they offer a sound profile that is arguably more enjoyable than the Plus version.
The missing LDAC support and lesser build materials are minor trade-offs considering the better tuning and similar performance in key areas. If your focus is on music enjoyment and daily practicality, the CMF Buds 2 stand out as the smarter pick.
