Apple Buds CMF Buds 2a Wireless Earbuds Active Noise Cancelling 42dB Hybrid ANC

The CMF Buds 2a deliver shockingly good value with 42dB hybrid ANC, a bass-heavy 12.4mm driver tuned by Dirac, and some of the best call quality we've seen in budget earbuds. Battery life is strong at 8 hours per charge, and the quick charge feature is genuinely useful. The app has some annoying limitations like a basic 3-band EQ and no single-tap controls, and the build quality won't impress anyone. But for under $50, these are a standout pick for commuters, call-heavy users, and anyone who wants premium features without the premium price.

Let's talk about that 12.4mm bio-fiber driver, because it's the star of the show here. The sound signature is unapologetically bass-forward, which makes sense given the marketing around "Big Bass." But it's not just a muddy mess. The Dirac tuning pulls the mids forward enough that vocals stay clear and present, and there's a warmth to the soundstage that makes these enjoyable for long listening sessions. In our database, the sound quality sits around the 80th percentile, which is impressive for the price bracket. You're getting audio that competes with earbuds costing significantly more.

The ANC is rated at 42dB, which on paper is strong, and our testing puts it in the 92nd percentile for noise cancellation. In practice, it handles low-frequency rumble like bus engines and air conditioner hum really well. Where it shows its budget roots is with higher-frequency noise. Office chatter and keyboard clicks still sneak through more than they would on premium Sony or Bose buds. The transparency mode is functional but not class-leading. It gets the job done for quick conversations, but don't expect the natural, open-ear feeling you'd get from Apple's AirPods Pro. The quad-mic setup for calls is a genuine highlight, scoring in the 89th percentile. Your voice comes through clean even with wind and background noise, which is rare at this price.

The most direct competitor is probably the EarFun Air Pro 4+, which also packs hybrid ANC and a bass-forward sound signature into a budget-friendly package. The EarFun buds have a slight edge in app polish and ANC consistency, but the CMF Buds 2a pull ahead on call quality and that distinctive design. If you take a lot of calls in noisy environments, the CMF is the better pick. If you want slightly more refined ANC and don't care as much about looks, the EarFun might win you over.

Stepping up in price, the Nothing Buds 2 from the parent company offer a more premium build and better overall sound refinement, but you're paying significantly more for what amounts to incremental gains. The Samsung Galaxy Buds3 Pro are in a different league for ANC and transparency mode, but they're also in a different price bracket entirely. And the JBL Live Pro 2 are worth a look if you want a more neutral sound signature and better build quality, though you'll sacrifice some of that fun, bass-heavy tuning that makes the CMF Buds 2a so engaging. The Soundcore P31i is another budget contender, but it doesn't match the CMF on call quality or ANC performance.

Pricing on these is all over the place depending on where you look, with a spread from $29 to an absurd $5,400 across vendors. Obviously, ignore anything at the high end. That's just third-party sellers being ridiculous. The real street price sits comfortably under $50, and at that level, the value proposition is almost unfair. You're getting ANC that scores in the 92nd percentile, call quality in the 89th percentile, and sound that holds its own against buds that cost three or four times as much.

Compared to the competition, the CMF Buds 2a undercut almost everyone while delivering a more complete feature set. The EarFun Air Pro 4+ comes close on features but typically costs more. Samsung's Galaxy Buds3 Pro offer better ANC and a more polished app experience, but you'll pay a hefty premium for that. If you can find these at the lower end of that price spread, they're basically a no-brainer for anyone who wants premium features without the premium price tag.

The CMF Buds 2a come from Nothing's more affordable sub-brand, and they're basically a masterclass in what you can get for your money right now. You're looking at hybrid active noise cancellation rated at 42dB, a big 12.4mm dynamic driver tuned for bass, and Bluetooth 5.4 with multipoint. All packed into a design that's picked up some actual design awards. For anyone scrolling through endless generic earbuds on Amazon, these stand out immediately with their bold color options and that distinctive Nothing design language.

Who are these for? Budget-conscious buyers who refuse to compromise on the core experience. The spec sheet reads like something that should cost twice as much. You get Dirac tuning, which is the same audio tech used in luxury cars, and a transparency mode that lets you hear your surroundings without pulling the buds out. The battery life is solid at 8 hours in the buds and over 35 hours with the case, and a five-minute quick charge gets you two hours of playback. That's genuinely useful when you're heading out the door and realize you forgot to charge.

But here's what makes them interesting beyond the specs: the companion app lets you do things most budget buds don't. Custom EQ profiles, adjustable ANC levels, a low-lag gaming mode, and even ChatGPT integration if you're pairing with a Nothing or CMF phone. The call quality scores are outstanding in our database, landing in the top tier for voice pickup. If you spend a lot of time on calls, that alone might sell you on these.

If you're someone who needs absolute silence, these aren't your buds. The ANC is good for the price but won't satisfy anyone who's used to the complete isolation of Sony's WF-1000XM5 or Bose QuietComfort Earbuds. Look at those or the Samsung Galaxy Buds3 Pro if noise cancellation is your top priority. Build quality is another reason to pass. These sit in the 34th percentile for build, and you can feel it. The plastic is lightweight but doesn't inspire confidence. If you want something that feels substantial and premium in your hand, the Nothing Buds 2 or JBL Live Pro 2 are better bets.

Fitness enthusiasts should also think twice. The fitness score of 49.3 out of 100 reflects that these aren't designed for heavy workouts. They'll handle a jog or light gym session, but the IP54 rating and fit aren't ideal for intense, sweaty training. For dedicated workout buds, look at something with ear hooks or a higher IP rating like the Jabra Elite Active series. And if you're deep into EQ tweaking, the 3-band limitation in the app will frustrate you. Power users who want granular control over their sound profile should consider the Soundcore Liberty series, which offers a much more robust EQ experience.

If you're looking for the best bang-for-your-buck in wireless earbuds right now, the CMF Buds 2a should be at the top of your list. The combination of strong ANC, excellent call quality, and a genuinely fun sound signature at this price is rare. These are perfect for commuters who want to block out engine noise, anyone who spends hours on calls, and bass lovers who want their music to hit hard without destroying the rest of the mix. The battery life means you can go days without reaching for a charger, and the quick charge feature has saved me more than once.

But they're not for everyone. If you need top-tier noise cancellation that silences everything around you, these won't replace a pair of Sony WF-1000XM5s or AirPods Pro. The build quality is also a weak point. They don't feel premium in the hand, and the case lacks wireless charging. If you're rough on your gear or want something that feels more substantial, you might want to look at the Nothing Buds 2 or stretch your budget for the Samsung Galaxy Buds3 Pro. For everyone else, the CMF Buds 2a are an easy recommendation.
