CMF Buds Pro Review: Worth The Hype?

The wireless earbud market keeps getting crowded every year. Many brands promise great features at low prices. But most fall short when you actually test them. The CMF Buds Pro 2 arrives with big claims and an even bigger value proposition.

This product comes from CMF by Nothing, a sub-brand known for making affordable tech that works. Today we dig deep into whether these earbuds deliver on their promises or just add to the noise.

This review tests every claim to see if CMF created something special or just another overhyped product.

Key Takeaways

• Outstanding Value for Money: The CMF Buds Pro 2 delivers premium features at just $59, making it one of the best budget wireless earbuds available today. You get 50dB hybrid noise cancellation, LDAC hi-res audio support, and a unique smart dial charging case that most competitors charge double for.
• Impressive Sound Quality: These earbuds feature 11mm dynamic drivers with Dirac tuning that produces powerful bass and clear vocals. The sound signature leans toward bass-heavy, which makes them perfect for gym sessions, commuting, and casual listening without sounding muddy.
• Smart Dial Innovation: The rotating dial on the charging case lets you control volume without touching your phone or earbuds. This unique feature sets CMF apart from every competitor in this price range and adds genuine convenience to daily use.
• Strong Battery Performance: You get up to 6.5 hours of playback on a single charge with ANC on, extending to 43 hours total with the charging case. Fast charging gives you 2.2 hours of playback from just 10 minutes, which saves you during rushed mornings.
• Solid Build Quality: Despite the budget price, these earbuds feel well-made with IP55 water resistance rating. They survive sweaty workouts and light rain without issues, though they lack the premium metal finishes of expensive alternatives.
• Minor Compromises: The main trade-offs include slightly weaker call quality compared to flagship models, no wireless charging support, and bass that might overwhelm treble-sensitive listeners. These compromises feel reasonable given the aggressive pricing.

Design and Build Quality

The CMF Buds Pro 2 makes a strong first impression right out of the box. The charging case features a circular design with a rotating dial on the front. This dial serves as the main control mechanism, letting you adjust volume levels with satisfying clicks. The case comes in multiple color options including Dark Grey, Blue, and Orange. Each color option maintains the same minimalist aesthetic that Nothing products are known for.

The earbuds themselves sit snugly in the case with strong magnets. They pop out easily when you need them but stay secure during transport. Each earbud weighs just 4.8 grams, making them light enough for extended wearing sessions. The stem design resembles Apple AirPods Pro but with a slightly thicker profile. The fit feels comfortable with the included silicone ear tips in three sizes.

Build materials consist mainly of plastic, which keeps costs down. But the plastic feels solid, not cheap or flimsy. The case has a matte finish that resists fingerprints better than glossy alternatives. One interesting design choice involves removable backplates on the earbuds. You can swap these for different colors or accessories, adding a personalization element rarely seen in budget products.

The IP55 rating means these earbuds handle sweat and light rain without problems. You can wear them during workouts without worry. The rating falls slightly below the IP67 standard of premium models, but proves sufficient for daily use. The charging case lacks water resistance, so keep it dry.

Smart Dial Charging Case

The smart dial represents the most innovative feature of the CMF Buds Pro 2. This rotating wheel on the case front controls volume levels for your connected device. You twist the dial clockwise to increase volume and counterclockwise to decrease it. The mechanism provides tactile feedback with each step, making adjustments feel precise and satisfying.

This feature solves a real problem. Many users find touchpad controls on earbuds finicky. Accidentally triggering controls happens constantly. The smart dial removes that frustration. You adjust volume without touching the earbuds or pulling out your phone. The convenience becomes apparent during commutes, workouts, or any situation where your phone stays in your pocket.

The dial also functions as a customizable button. A single press plays or pauses music. Long presses can switch between ANC modes or activate voice assistants. The Nothing X app lets you customize these actions based on your preferences. The dial spins smoothly with minimal resistance. It feels durable enough to withstand daily use for years.

Battery life for the case remains strong despite the smart dial feature. The case holds enough charge to refill the earbuds five times. The dial draws minimal power, so it does not significantly impact overall battery performance. An LED indicator on the case shows remaining charge levels at a glance.

Sound Quality and Audio Performance

Sound quality stands as the most critical aspect of any earbuds. The CMF Buds Pro 2 delivers impressive audio for its price point. The 11mm dynamic drivers produce rich, full-bodied sound with emphasis on bass frequencies. Bass lovers will appreciate the punch these earbuds deliver. Electronic music, hip hop, and pop genres sound particularly engaging with deep, resonant low end.

The Dirac tuning helps balance the sound signature. Mids come through clearly, which means vocals and instruments maintain good separation. You can hear distinct layers in complex tracks without everything mushing together. The treble extends reasonably well, though it takes a backseat to the bass-forward profile. Some listeners might find the highs lack sparkle compared to neutral-tuned alternatives.

The earbuds support LDAC codec over Bluetooth 5.3. This codec enables hi-res audio streaming with compatible devices like Android phones. LDAC transmits three times more data than standard SBC codec, preserving more detail and nuance. Apple users get AAC support, which provides decent quality though not quite LDAC level.

The soundstage feels intimate rather than expansive. These are not audiophile earbuds that create a huge sense of space. But for casual listening during commutes or workouts, the presentation works well. Gaming performance proves adequate for mobile games, though serious gamers might notice slight latency. A low-latency gaming mode helps reduce lag during competitive play.

Customization options exist through the Nothing X app. The app includes multiple EQ presets plus a custom EQ with adjustable frequency bands. You can tune the sound to your preferences, reducing bass or boosting treble as needed. The app also supports firmware updates to improve performance over time.

Top 3 Alternatives for CMF Buds Pro 2

The wireless earbud market offers plenty of competition in the under $60 range. The TOZO NC9 sells for around $28 and provides hybrid ANC, IPX8 waterproofing, and 59 hours of total playtime. These earbuds deliver solid value though they lack the smart dial and LDAC support of CMF.

The Soundcore P30i by Anker costs $30 and includes noise cancellation, 45 hours of playtime, and a case that doubles as a phone stand. Anker’s reputation for quality and customer service makes these a safe choice, though sound quality leans more neutral than bass-heavy.

The Adaptive Hybrid ANC earbuds at $60 match CMF’s price point with 6-mic ENC, Hi-Res audio, and 48 hours of playtime. These offer multipoint connection for switching between devices easily, a feature CMF lacks. However, they miss the unique smart dial interface that makes CMF special.

Noise Cancellation Performance

The CMF Buds Pro 2 advertises 50dB of hybrid active noise cancellation. This spec puts it on paper with much more expensive models. In real-world testing, the ANC performs well for the price. It effectively reduces low-frequency rumble from airplane engines, bus motors, and air conditioning units. The reduction feels substantial enough to create a quieter listening environment.

Mid-range frequencies like office chatter and keyboard typing get attenuated reasonably well. You still hear voices in quiet environments, but they become less intrusive. The earbuds do not isolate you completely from your surroundings, which actually helps with safety awareness during outdoor walks.

High-frequency sounds like sibilance and sharp noises cut through more easily. The ANC struggles with sudden sounds like dog barks or door slams. This limitation exists in most earbuds under $100, so it does not count as a specific weakness. Premium models from Sony or Bose handle high frequencies better but cost three times as much.

The transparency mode works adequately. It amplifies outside sounds through the microphones so you can hear announcements or conversations without removing the earbuds. The quality sounds slightly artificial compared to high-end alternatives, but it serves its purpose. You cycle between ANC, transparency, and off modes through the app or earbud controls.

Wind noise affects the microphones during outdoor use. Walking on windy days creates noticeable interference. The earbuds lack dedicated wind-reduction algorithms, so this becomes a minor annoyance during certain weather conditions.

Battery Life and Charging

Battery performance exceeds expectations for budget earbuds. The CMF Buds Pro 2 delivers up to 6.5 hours of continuous playback with ANC enabled. Turning off ANC extends this to around 8 hours. These numbers match or beat many competitors in the same price range.

The charging case provides approximately five full charges, bringing total playtime to 43 hours. This means you can go nearly a week between case charges with moderate daily use. Heavy users might need to charge the case every three to four days. The case charges via USB-C cable, which has become the universal standard.

Fast charging support proves genuinely useful. Placing the earbuds in the case for just 10 minutes provides up to 2.2 hours of playback time. This feature saves you when you forgot to charge overnight and need to leave quickly. A full charge of the earbuds takes about 90 minutes, while the case needs roughly 2 hours to reach 100%.

The case lacks wireless charging capability. This feature exists in some competitors but adding it would likely increase the price. For users who already have wireless charging pads, this represents a minor inconvenience. But USB-C charging works fine and remains widely available.

Battery degradation will occur over time like all rechargeable devices. CMF does not specify the expected number of charge cycles, but lithium-ion batteries typically maintain 80% capacity after 500 cycles. With proper care, these earbuds should provide reliable battery life for at least two years.

Call Quality and Microphone Performance

The CMF Buds Pro 2 includes six microphones total across both earbuds. This setup enables beamforming technology that focuses on your voice while reducing background noise. Call quality performs adequately in quiet indoor environments. Your voice comes through clearly with minimal distortion or robotic artifacts.

Background noise reduction works reasonably well in moderate noise. Coffee shop chatter or office sounds get suppressed to manageable levels. The person on the other end can hear you without too much interference. However, very loud environments like busy streets or construction sites overwhelm the noise cancellation. Your voice becomes harder to understand in these situations.

Wind noise during outdoor calls remains problematic. The microphones pick up wind buffeting sounds that interfere with voice clarity. This issue affects most wireless earbuds without physical wind screens. Making calls while walking on windy days produces poor results.

The Clear Voice Technology 3.0 helps enhance vocal clarity. This AI-powered processing identifies speech patterns and amplifies them relative to background noise. It works better than older CMF models but still falls short of premium earbuds with more advanced algorithms. Business users who make frequent calls might want to invest in specialized headsets.

Video call performance mirrors voice call quality. Apps like Zoom, Teams, and FaceTime all work without major issues in controlled environments. The microphones provide sufficient clarity for casual video chats with friends and family. Professional presentations requiring crystal-clear audio might demand better equipment.

Software and App Features

The Nothing X app controls all aspects of the CMF Buds Pro 2. The app works with both iOS and Android devices, providing cross-platform compatibility. The interface follows a clean, minimalist design philosophy that matches Nothing’s brand aesthetic. Navigation feels intuitive with clearly labeled sections.

The app displays real-time battery levels for both earbuds and the charging case. This helps you monitor charge status at a glance. You can customize touch controls through the app, assigning different actions to single, double, triple taps, and long presses. Control options include play/pause, skip tracks, volume adjustment, ANC mode switching, and voice assistant activation.

Multiple EQ presets exist for different music genres and listening preferences. The “Bass Boost” preset enhances low frequencies for electronic music. “Vocal” mode emphasizes mid-range frequencies for podcasts and audiobooks. “Treble Boost” brightens the sound signature for classical music. A custom EQ allows precise adjustments across multiple frequency bands.

The app includes a fit test that plays sound through each earbud to verify proper seal. This test helps you choose the right ear tip size for optimal sound quality and noise cancellation. Firmware updates download and install directly through the app. CMF has released several updates since launch, addressing bugs and improving performance.

Find My Earbuds feature makes locating misplaced earbuds easier. The app plays a loud tone through the earbuds to help you locate them. This works only when the earbuds remain in Bluetooth range, so it will not find earbuds left across town.

Comfort and Fit

Comfort matters for earbuds you wear for hours daily. The CMF Buds Pro 2 achieves good ergonomics despite not using custom molding. The earbuds weigh just 4.8 grams each, which reduces fatigue during extended sessions. The light weight means you barely notice them after initial insertion.

The stem design distributes weight efficiently. Most of the earbud mass stays outside your ear canal rather than pressing inward. This design prevents the sensation of objects being jammed into your ears. The smooth plastic housing avoids sharp edges or pressure points.

Three sizes of silicone ear tips accommodate different ear canal sizes. Small, medium, and large options come in the box. Most users find the medium tips work well as a starting point. The tips create a secure seal for both sound quality and noise isolation. Passive isolation from the ear tips blocks external sound even with ANC disabled.

The earbuds stay secure during movement. Light jogging and gym workouts pose no problems. The earbuds do not work loose or require constant adjustment. However, intense activities like running or jumping might cause some shifting. Users who want maximum security during vigorous exercise might prefer earbuds with ear hooks or fins.

Hot weather affects comfort negatively. The plastic housing and silicone tips trap some heat and moisture during summer workouts. Your ears might feel sweaty after long sessions. Taking breaks to air out your ears helps maintain comfort. This issue affects most in-ear designs regardless of brand or price.

Connectivity and Bluetooth Performance

The CMF Buds Pro 2 uses Bluetooth 5.3 for wireless connectivity. This version of Bluetooth provides stable connections with lower power consumption than older standards. Pairing new devices takes just seconds through the standard Bluetooth menu. The earbuds enter pairing mode automatically when removed from the case for the first time.

Connection range extends to approximately 30 feet in open spaces. Obstacles like walls reduce this range as expected. Walking around a small apartment with your phone in one room works fine. Moving to different floors might cause dropouts depending on building construction.

The earbuds remember up to eight previously paired devices. Switching between devices requires manual disconnection and reconnection through Bluetooth settings. The lack of multipoint connection means you cannot stay connected to two devices simultaneously. This limitation prevents seamless switching between your phone and laptop.

Connection stability remains solid during testing. Music playback continues without interruptions or stutters in typical use cases. Crowded areas with many Bluetooth devices like airports or shopping malls might cause occasional interference. But these situations affect most wireless earbuds regardless of price point.

Latency feels acceptable for video watching and casual gaming. You notice minimal delay between on-screen action and corresponding audio. The low-latency gaming mode reduces lag further for competitive mobile gaming. However, serious gamers and audio professionals might still detect slight delays compared to wired connections.

Gaming Performance

Mobile gaming represents a growing use case for wireless earbuds. The CMF Buds Pro 2 handles gaming reasonably well for casual players. The low-latency mode reduces audio delay to approximately 60ms. This improvement makes rhythm games and shooters more playable than standard mode.

The bass-heavy sound signature benefits action games with explosions and environmental effects. The powerful low end adds impact to gaming audio, making experiences feel more immersive. Battle sounds and engine noises come through with satisfying weight.

The soundstage limitation becomes more apparent during gaming. Positional audio cues work adequately but lack the precision of gaming-focused headsets. Determining exact enemy locations in competitive shooters proves challenging. The stereo imaging helps but does not match the spatial accuracy of products designed specifically for gaming.

Voice chat quality through the microphones works for casual gaming sessions with friends. Your teammates can understand you in quiet environments. Background noise suppression helps but does not eliminate all interference. Dedicated gaming headsets with boom microphones provide superior communication quality.

The battery life supports extended gaming sessions without running out of charge mid-game. Six hours of continuous use covers most gaming marathons. The fast charging feature helps when you need quick top-ups between sessions.

Durability and Longevity

The CMF Buds Pro 2 feels well-constructed despite the budget pricing. The plastic housing withstands normal handling without creaking or flexing. The earbuds survive accidental drops from table height onto hard floors. However, the plastic will show scratches and scuff marks over time with regular use.

The IP55 rating provides decent protection against sweat and moisture. Gym sessions and light rain do not damage the earbuds. But heavy rain or submersion will cause problems. The rating sits below the IP67 standard of premium models, so exercise caution around water.

The charging case hinge mechanism operates smoothly with no wobble or looseness. The magnets holding the earbuds remain strong after weeks of testing. The smart dial continues functioning normally with consistent resistance and tactile feedback. The case shows minor scratches on the matte finish but nothing that affects functionality.

Battery longevity depends on usage patterns and charging habits. Lithium-ion batteries degrade gradually over hundreds of charge cycles. Following best practices like avoiding extreme temperatures and not letting batteries fully discharge helps maximize lifespan. Expect the earbuds to maintain acceptable performance for two to three years of regular use.

The removable backplates on the earbuds add durability concerns. The attachment mechanism could weaken over time with frequent swapping. Users who leave the default backplates installed avoid this potential issue. Replacement parts do not appear readily available if pieces break or get lost.

Value Proposition and Competition

The CMF Buds Pro 2 delivers exceptional value at $59. The feature set competes directly with products costing $100 to $150. The smart dial alone represents innovation you will not find in competing budget models. The inclusion of LDAC hi-res audio support, 50dB ANC, and respectable sound quality makes these earbuds a standout value.

Competitors in the same price range make compromises. The Soundcore P30i lacks LDAC and features weaker ANC. The TOZO NC9 costs less but misses premium features like advanced tuning and smart controls. Nothing Ear (a) offers similar performance but costs more without the smart dial. The QCY MeloBuds Pro competes on sound quality but lacks the unique case design.

The value proposition extends beyond raw specifications. The Nothing X app provides robust customization options. Regular firmware updates improve performance over time. The build quality exceeds expectations for a $59 product. The included accessories like multiple ear tips and USB-C cable complete the package.

The main competition comes from CMF’s own products. The CMF Buds 2 Plus costs more but provides better sound quality and longer battery life. The standard CMF Buds costs less but sacrifices the smart dial and LDAC support. Users must decide which features matter most for their needs and budget.

Who Should Buy CMF Buds Pro 2

The CMF Buds Pro 2 suits buyers who want premium features without premium prices. First-time wireless earbud buyers get an excellent introduction to the category. The combination of good sound quality, effective ANC, and innovative controls creates positive first impressions.

Budget-conscious consumers who want the best bang for their buck should strongly consider these earbuds. The $59 price point delivers far more value than competing products. Students, young professionals, and anyone watching their spending can enjoy high-quality audio without financial strain.

Bass lovers will appreciate the sound signature. The powerful low end makes these earbuds ideal for gym workouts, commutes, and casual listening. Electronic music, hip hop, and pop genres sound particularly engaging. The EQ customization lets you dial back bass if needed, but the default tuning favors bass enthusiasts.

Android users benefit most from the LDAC codec support. Apple device owners still get good sound quality through AAC codec but miss the hi-res audio capabilities. Multi-device users might feel frustrated by the lack of multipoint connection.

Audiophiles and critical listeners should look elsewhere. The bass-forward tuning and limited soundstage do not satisfy demanding ears. The treble extension and detail retrieval fall short of audiophile-grade earbuds. But those products cost significantly more.

Limitations and Drawbacks

No product achieves perfection, especially at budget prices. The CMF Buds Pro 2 makes some compromises worth understanding before purchase. The call quality underperforms in noisy environments. Wind noise interferes with outdoor calls. Users who make frequent calls might prefer earbuds with more advanced microphone systems.

The lack of wireless charging disappoints users with existing charging pads. Adding this feature would increase costs, but some competitors include it at similar prices. The USB-C charging works fine but feels less convenient than dropping the case on a wireless pad.

The bass-heavy sound signature will not please everyone. Treble-sensitive listeners might find the highs recessed. Classical music and acoustic genres lose some detail and sparkle. The EQ helps but cannot completely transform the fundamental tuning.

The absence of multipoint connectivity limits functionality. Users who switch between phone and laptop frequently must manually reconnect each time. This extra step becomes tedious for people juggling multiple devices. Premium earbuds offer seamless device switching.

The plastic construction shows wear over time. Scratches and scuff marks appear on the case and earbuds with regular use. The matte finish hides some damage but does not prevent it entirely. Users who value pristine appearance might feel disappointed after several months.

Comparison With Premium Models

Comparing budget earbuds to premium models highlights both strengths and limitations. The Sony WF-1000XM5 costs more than three times as much at $200+. Sony offers superior noise cancellation, better call quality, and wireless charging. The sound quality provides more detail and refinement. But CMF delivers 80% of Sony’s performance at 30% of the cost.

The Apple AirPods Pro 2 at $249 provides the best experience for iPhone users. The H2 chip enables features like Adaptive Audio and Conversation Awareness. Spatial audio creates immersive soundscapes. The MagSafe charging case adds convenience. But Android users cannot access many features, making AirPods a poor value outside the Apple ecosystem.

The Nothing Ear (2) represents the premium offering from CMF’s parent brand. It costs around $149 and delivers better overall performance. The sound quality shows more balance and refinement. The ANC performs slightly better. The build materials feel more premium. But the Nothing Ear (2) lacks the smart dial that makes CMF unique.

The Jabra Elite 85t at $180 offers excellent call quality and reliable connectivity. The hear-through mode sounds natural. The build quality inspires confidence. But the Elite 85t shows its age with older Bluetooth technology and bulkier design. The CMF Buds Pro 2 feels more modern despite costing a third as much.

These comparisons illustrate an important point. Premium earbuds provide incrementally better experiences in multiple areas. But the improvements do not justify triple or quadruple the cost for many users. The CMF Buds Pro 2 offers the best features most people actually use at a price anyone can afford.

Final Verdict

The CMF Buds Pro 2 represents outstanding value in the wireless earbud market. The $59 price point delivers features and performance that compete with products costing significantly more. The innovative smart dial charging case provides genuine convenience that other brands should copy. The sound quality satisfies casual listeners with its engaging bass-forward profile.

The earbuds excel at their intended purpose. They provide enjoyable audio for daily commutes, gym sessions, and home listening. The effective noise cancellation creates peaceful environments in noisy settings. The battery life lasts through long days without requiring frequent recharging. The comfortable fit accommodates extended wearing sessions.

Minor compromises exist throughout the product. The call quality stumbles in challenging environments. The lack of wireless charging and multipoint connectivity feels limiting. The bass-heavy tuning will not please everyone. But these trade-offs feel acceptable given the aggressive pricing strategy.

Buyers seeking the best bang for their buck should strongly consider the CMF Buds Pro 2. The combination of sound quality, features, and innovation creates a compelling package. Few products deliver this much value at such a low price point. The smart dial alone justifies trying these earbuds.
