4.2 out of 5 - Best Budget ANC Earbuds with Smart Case
Product Overview
The CMF Buds 2 Pro is Nothing's budget brand CMF's most innovative true wireless earbuds yet, proving that groundbreaking features don't have to come with a premium price tag. The standout feature is the revolutionary Smart Dial built into the charging case — a tactile, clicky wheel that lets you control volume, skip tracks, and activate your voice assistant without ever touching your phone or the earbuds themselves. This unique feature transforms the charging case from a passive accessory into an active control hub, something no other earbuds under $100 offer.
Beyond the Smart Dial, the Buds 2 Pro packs serious audio credentials. The 11mm dynamic drivers deliver a powerful, bass-forward sound signature that brings electronic music and hip-hop to life with deep, rumbling low-end. LDAC codec support on Android devices enables high-resolution wireless audio streaming, while the 50dB adaptive ANC creates an effective barrier against ambient noise. The Nothing X app unlocks extensive customization including Ultra Bass levels 1-5, 6 EQ presets, spatial audio, and ChatGPT integration on supported Nothing phones. Our expert team at Devixo Store has thoroughly tested these earbuds across commuting, workouts, gaming, and calls to bring you a comprehensive, honest review.
Why Buy This Product?
The CMF Buds 2 Pro stands out as the most innovative budget true wireless earbuds for several compelling reasons. First and foremost, the Smart Dial on the charging case is a genuine game-changer — no other earbuds under $100 offer this level of physical control convenience. The tactile, clicky wheel feels satisfying to use and lets you adjust volume, skip tracks, and activate your voice assistant without reaching for your phone. You can customize the dial's functions through the Nothing X app, assigning different actions to twist, single press, double press, triple press, and long press. The dial can also be deactivated entirely if you prefer to avoid accidental activation when the case is in your pocket or bag.
Second, the audio performance punches well above the $59 price point. The 11mm drivers produce a bass-heavy, energetic sound signature that makes electronic music, hip-hop, and pop tracks incredibly engaging. The Ultra Bass setting (adjustable from level 1 to 5) lets you dial in exactly how much low-end thump you want — at level 3 (default), the bass is powerful but controlled, while level 5 delivers head-rattling intensity for true bassheads. The LDAC codec on Android unlocks noticeably better detail and clarity. The 50dB ANC effectively handles low-frequency rumble like airplane engines and train noise. At our store, we rigorously test every product for audio quality, ANC effectiveness, call clarity, battery accuracy, and build durability — and the CMF Buds 2 Pro consistently earns top marks as the most feature-packed budget earbuds available.

Frequently Asked Questions
1
How does the Smart Dial on the CMF Buds 2 Pro case work?
The Smart Dial is a unique physical control wheel built into the charging case. You can twist it to adjust volume with satisfying clicky feedback, press it to control playback (skip tracks, pause/play), and customize its functions through the Nothing X app. The app lets you assign different actions to twist, single press, double press, triple press, and long press. You can also deactivate the dial entirely to prevent accidental activation when the case is in your pocket. The dial works on both Android and iOS devices once configured in the app. Note that the notification sound played when turning the dial can be much louder than your current listening volume, which some users find startling at high volumes.
2
How long does the battery last on the CMF Buds 2 Pro?
The CMF Buds 2 Pro delivers up to 11 hours of continuous playback on a single earbud charge with ANC turned off. With ANC enabled, battery life drops to approximately 6.5-8 hours per charge. The charging case provides an additional 32-35 hours, bringing the total to approximately 43 hours (ANC off) or 26-32 hours (ANC on). A 10-minute quick charge provides approximately 3 hours of playback with ANC off, or under 2 hours with ANC on. The case charges via USB-C and does not support wireless charging. If you enable LDAC high-resolution audio codec on Android, battery life per charge drops to approximately 4 hours due to the higher bandwidth requirements.
3
How good is the active noise cancellation on the CMF Buds 2 Pro?
The CMF Buds 2 Pro features 50dB adaptive ANC that performs well for the price, especially in the low-frequency range. It effectively reduces constant noises like traffic rumble, airplane engines, and air conditioning hum by around 80%. However, it is less successful at blocking sudden sounds like door slams, keyboard typing, and people talking — these still creep through. High-pitched noises like horns and alarms are also not fully eliminated. The ANC produces some audible white noise, which is noticeable in very quiet environments. The transparency mode works reasonably well for hearing your surroundings, though it is not as natural-sounding as premium competitors. Overall, the ANC is comparable to other earbuds in the $50-70 range like the Soundcore P30i, but slightly weaker than the SoundPEATS T3 Pro and QCY MeloBuds Pro.
4
What is the sound quality like on the CMF Buds 2 Pro?
The CMF Buds 2 Pro delivers a bass-heavy, energetic sound signature that is immediately noticeable. The 11mm drivers produce deep, rumbling sub-bass and powerful mid-bass thumps that bring electronic music, hip-hop, and EDM to life. By default, the Ultra Bass is set to level 3, which provides substantial low-end without completely overwhelming the mids. At level 5, the bass becomes extremely powerful — some users describe it as head-rattling. The lower mid-tones are thick and warm, giving body to guitars and pianos. Vocals have a warm undertone but can sound slightly thick rather than airy. Higher frequencies like violins and cymbals are darker than average and do not extend very far. The soundstage is modest — these are not spacious earbuds, but the spatial audio mode in the app adds a layer of reverb that simulates width. For a more balanced sound, switch to the Pop EQ preset or create a custom EQ in the Nothing X app.
5
Does the CMF Buds 2 Pro support high-resolution audio?
Yes, the CMF Buds 2 Pro supports LDAC codec for high-resolution wireless audio streaming on compatible Android devices. LDAC transmits audio at up to 990 kbps, which is nearly three times the bitrate of standard SBC Bluetooth audio. This results in noticeably better detail retrieval, tighter bass, and a more spacious sound compared to AAC or SBC. The earbuds are also Hi-Res Audio certified by the Japan Audio Society. However, there are trade-offs when using LDAC: it significantly reduces battery life to approximately 4 hours per charge, can cause Bluetooth instability in crowded wireless environments, and introduces slight audio lag during video playback. For most users, the default AAC or SBC mode provides perfectly adequate quality with better stability and battery life. LDAC can be enabled manually in the Nothing X app under Bluetooth settings on Android.
6
Can I use the CMF Buds 2 Pro for phone and video calls?
Yes, the CMF Buds 2 Pro features a six-microphone array with AI noise suppression for calls. In quiet environments, your voice comes through clear and natural with good volume. Background noise like office chatter or traffic is reasonably suppressed, though not completely eliminated. Wind performance is decent — your voice remains understandable in light wind, though some rumbling may accompany your voice. In very noisy environments like food courts, the earbuds apply heavier noise gating which can occasionally cut into your voice. The CMF Buds 2 Pro handles calls slightly better than the standard CMF Buds 2, with clearer voice reproduction. Overall, call quality is good for the price and suitable for daily phone calls, video conferences, and virtual meetings.
7
Is the CMF Buds 2 Pro good for working out and running?
Yes, the CMF Buds 2 Pro is well-suited for workouts and running thanks to its IP55 water and dust resistance rating. The first digit (5) means the earbuds are protected against dust ingress, while the second digit (5) means they can withstand water jets from any direction — making them resistant to sweat, light rain, and splashes. The lightweight design and included ear tip sizes (typically S, M, L) help achieve a secure fit that stays in place during movement. The diagonal earpiece design is easy to insert and comfortable for extended wear. However, these are not designed for swimming or submersion in water. For intense gym sessions, weight training, jogging, and outdoor activities, they perform reliably. The bass-heavy sound signature also makes them particularly motivating for workout playlists.
8
Can I connect the CMF Buds 2 Pro to two devices at once?
Yes, the CMF Buds 2 Pro supports multipoint Bluetooth connection, allowing simultaneous pairing with two devices. You can connect to your smartphone and laptop at the same time, and switching between them is seamless — when a call comes in on your phone while music plays from your laptop, the earbuds automatically route the call audio. Similarly, pausing playback on one device and starting on another triggers an automatic switch with minimal delay. This feature works on both Android and iOS. Note that you need to enable multipoint connection in the Nothing X app. Some users report that third-party media apps may experience brief audio output issues when switching, which can be resolved by toggling the multipoint feature off and on again in the app settings.
9
What customization options are available in the Nothing X app?
The Nothing X app offers extensive customization for the CMF Buds 2 Pro. You can check battery levels for each earbud, adjust ANC strength (Adaptive, High, Moderate, Low, or Off), and toggle transparency mode. For sound, you get 6 EQ presets (Balanced, Pop, Rock, Jazz, Classical, Custom) plus a 3-band custom equalizer, Ultra Bass levels 1-5, and spatial audio on/off. The Smart Dial can be customized with different actions for twist, single press, double press, triple press, and long press. You can also set up ChatGPT integration on supported Nothing phones for voice assistant control. Additional features include low-latency gaming mode, in-ear detection toggle, find my earbuds, ear tip fit test, firmware updates, and the ability to switch to LDAC codec on Android. The app is available for both iOS and Android and is widely praised for its sleek, user-friendly design.
10
What is the difference between CMF Buds 2 Pro and CMF Buds 2 Plus?
The CMF Buds 2 Pro ($59) and Buds 2 Plus ($69) share many similarities but have key differences. The Pro features the unique Smart Dial on the case for physical volume and playback control, while the Plus replaces this with a non-functional rotating lanyard loop. The Plus offers Smart Adaptive ANC (vs standard adaptive on Pro), Personal Sound powered by Audiodo for personalized hearing profiles, and significantly longer battery life — 10+ hours per charge vs 6.5-8 hours on the Pro. The Plus also has slightly better overall sound refinement with tighter bass and cleaner treble. However, the Pro's interactive dial is a genuinely useful feature that many users prefer. The Plus is $10 more expensive. If you value the Smart Dial's convenience and don't mind slightly shorter battery life, the Pro is the better choice. If you prioritize battery life, personalized sound, and don't care about the dial, the Plus offers more for the extra $10.
