CMF's answer to the flagship ANC earbud
Nothing's budget sub-brand has made a specific bet with the Buds Pro 2: buyers don't want fewer features at a lower price, they want the same features minus the premium markup. That's the pitch here. Hybrid ANC rated at 50dB, LDAC hi-res audio, and a 6-microphone array aren't features usually associated with earbuds in this price bracket, and CMF is leaning on that gap directly.
The design carries over CMF's transparent-accent aesthetic, which has become a recognizable signature for the brand rather than a Nothing knockoff. It's a small thing, but it means the Buds Pro 2 don't disappear into the sea of identical black earbud cases at every price point.
It's aimed at someone who wants the feature checklist of a premium product without paying premium prices, and mostly delivers on that promise on paper.
Fifty decibels of ANC at this price is unusual
Most earbuds in this price range treat noise cancellation as an afterthought, something to check off a box rather than genuinely engineer. CMF's claimed 50dB reduction, paired with a frequency range up to 5000 Hz, is a spec typically reserved for far pricier earbuds. As with any ANC claim, steady low-frequency noise (engine drone, HVAC hum) will get canceled far more effectively than sudden sounds like a dog bark or a stranger's phone call.
The adaptive ANC mode is a genuinely useful addition: it detects leakage between the earbud and ear canal and compensates automatically, which matters more than raw dB numbers for anyone whose ear shape doesn't perfectly match a standard eartip.
LDAC support is the other headline feature, and it's a real differentiator. Most budget earbuds cap out at AAC or SBC, which are fine but leave meaningful audio detail on the table. LDAC's higher transmission rate can deliver a noticeably crisper listen, though only for Android users pairing with a source and streaming service that actually pushes high-bitrate audio. IPhone owners won't see the benefit at all, since LDAC isn't supported on iOS.
The Smart Dial on the case is a small but clever piece of hardware. Physical controls that don't rely on tapping a touch-sensitive earbud stem (and accidentally skipping a track while adjusting your earbud) are underrated, and CMF deserves credit for building one in rather than relying purely on the app.
Living with the case, the dial, and the app
Day to day, the Nothing X app is where most of the customization happens: five adjustable levels of the Ultra Bass 2.0 low-end boost, ANC mode switching, and presumably firmware updates. Buyers who skip the app entirely will still get a usable pair of earbuds out of the box, but they'll miss most of what makes the Pro 2 worth the price.
Battery life follows a familiar pattern for wireless earbuds: roughly 10 hours per charge from the buds themselves, stretching to 43 hours total with the case topped off. That's enough for a long flight or several days of commuting without needing to think about charging, though as with any ANC-equipped earbud, running noise cancellation and higher volumes will pull that number down.
IP55 water resistance means sweat during a workout or a sudden downpour on the walk home won't be a concern, though it's not rated for submersion, so swimming or heavy rinsing is off the table.
Where the budget shows through
Specs are one thing, sound signature and fit are another, and CMF doesn't have the decade of acoustic engineering reputation that companies like Sony or Sennheiser carry. The Buds Pro 2 look competitive on paper, but that's a different claim than being competitive in a side-by-side listen.
LDAC is a genuine feature, but it's also an easy one to oversell. Most streaming happens over standard Bluetooth codecs regardless of what the earbuds support, and if your phone is an iPhone, the entire feature is irrelevant to your listening experience.
This is also a newer entrant from a newer sub-brand, so there isn't the same long history of user reports on things like case hinge durability or ANC performance holding up after a year of daily use that older, more established earbud lines have built up over time.
The specs that matter
Strong reduction of steady noise like engine hum or office HVAC, though sudden sounds and voices will still get through to some degree.
Covers a long workday or flight without a recharge, though ANC and higher volume will shorten the single-charge number.
Android users streaming high-bitrate audio can get a noticeably richer sound; iPhone owners won't see any benefit since iOS doesn't support LDAC.
Handles sweat and rain fine for workouts and commutes, but isn't built for swimming or submersion.
More mics generally means better voice pickup on calls and more accurate ANC leakage detection.
Lets you adjust volume and switch modes without tapping the earbud stem, avoiding accidental skips or mode changes.
Unlocks bass tuning (5 adjustable levels), ANC mode selection, and other customization not available from the earbuds alone.
Who this product fits
The daily transit commuter
The 50dB ANC rating and adaptive leakage compensation should take the edge off subway rumble and bus engine noise, making a crowded commute noticeably less fatiguing without needing to max out the volume.
The Android listener chasing better sound
With LDAC support and a 12.4 mm bio-fibre driver, an Android user streaming from a hi-res-capable service can expect a clearer, more detailed listen than typical budget earbuds deliver over standard Bluetooth codecs.
The gym-and-rain commuter
IP55 water resistance means sweat during a workout and a sudden rain shower on the walk home aren't a concern, though these earbuds still aren't meant for swimming.
The iPhone-only shopper
An iPhone user should treat the LDAC feature as irrelevant since iOS doesn't support the codec, and should judge this purchase mainly on ANC performance, fit, and price instead.
What else to compare
A few other paths are worth knowing before settling on the Pro 2.
CMF by Nothing CMF Buds Pro 2 FAQ
Does the CMF Buds Pro 2 work with iPhones?
Yes, it pairs over standard Bluetooth, but the LDAC hi-res codec only works with Android devices that support it, since iOS doesn't offer LDAC. IPhone users will still get ANC, the app features, and standard audio quality.
How long does the battery actually last?
CMF rates the earbuds at about 10 hours per charge, with the case providing additional recharges for a total of roughly 43 hours. Running ANC or listening at higher volumes will reduce the single-charge number.
Is the Smart Dial necessary, or can I just use touch controls?
The dial is a physical alternative to touch controls on the case itself, useful for adjusting volume or switching ANC modes without tapping the earbud stem. It's a convenience feature, not a requirement.
Are these earbuds waterproof enough for the gym?
The IP55 rating covers sweat and light rain, which suits gym use and commuting, but the earbuds aren't rated for submersion or swimming.
Do I need the Nothing X app to use these earbuds?
No, but skipping the app means missing out on ANC mode switching, the five-level bass adjustment, and other customization that differentiates this model from a basic pair of earbuds.
Worth it if the codec and features actually apply to you
CMF has assembled a spec sheet that reads like it belongs to a much pricier pair of earbuds: strong ANC, LDAC support, a 6-mic array, and a genuinely useful physical control on the case. For the right buyer, an Android user who wants noise cancellation and better wireless audio without flagship pricing, that combination is hard to beat at this level.
The honest caveat is that several of the headline features only pay off under specific conditions. LDAC needs the right phone and streaming source, and no earbud's ANC claim tells the whole story once you're dealing with a crying toddler instead of a droning engine. Judge the Buds Pro 2 on what it does well, real ANC, real battery life, a case that doesn't feel like an afterthought, rather than on the spec sheet alone, and it's a sound buy for anyone shopping in this price range.
