CMF Buds Pro 2 Review — LDAC, -45dB ANC & Dual Driver Tested (2026)

CMF Buds Pro 2 Specifications

The CMF by Nothing Buds Pro 2 specification list is where the value argument starts. Dual driver architecture, LDAC at $60, and -45dB ANC together represent a combination that typically costs $80–$120 from competing brands. Here are the full specs covered in this review.

Design and Build — Nothing's Sub-Brand DNA

The CMF Buds Pro 2 earbuds carry clear Nothing DNA — transparent case with exposed internals visible through the shell, stem design with a distinctive colour accent, and the CMF logo embossed on the outer earcup. At $60, the build quality communicates Nothing's aesthetic priorities more than premium materials. The stem is plastic but solid. Touch controls register cleanly without accidental triggers.

Earcup padding uses silicone tips in S, M, and L sizes. The medium tips created a secure passive seal immediately on testing. IPX5 water resistance handled gym sweat and a light rain shower without issues across the two-week test period. Additionally, the case's transparent design shows the earbuds clearly — which makes checking whether they're seated and charging straightforward without opening the case.

What surprised me: the case lid magnetic closure is satisfying and precise — it matches the quality of earbuds costing $20–$30 more. The honest limitation is earcup depth. At the 3-hour mark during continuous WFH use, I noticed ear canal awareness — not pain, but presence. Deeper silicone tips help, but CMF by Nothing earbuds at this price can't match the long-wear comfort of the Nothing Ear (a).

CMF Buds Pro 2 Sound Quality Review — Dual Driver Difference

The CMF Buds Pro 2 sound quality review starts with the most important question: does dual driver actually make an audible difference at $60? The answer is yes — specifically on LDAC with Android. The 11mm dynamic driver handles bass and mids while the 6mm planar tweeter manages upper-mid and treble detail. The division of labour produces noticeably cleaner treble than single-driver earbuds at this price.

I tested LDAC performance on "What Was I Made For?" by Billie Eilish on Spotify lossless via my Pixel 7 Pro. Switching between LDAC and AAC, the difference was immediately audible. LDAC revealed subtle breathy detail in the vocal reverb tail that AAC compressed away entirely. The planar tweeter handles that treble resolution. At $60, this is the first earbud I've tested where LDAC sounds genuinely different rather than marginally different.

The sound signature is W-shaped — elevated bass, present mids, and boosted treble that the planar tweeter delivers cleanly without the harshness common in single-driver budget earbuds. "Hotel California" by Eagles showed surprisingly good guitar channel separation in the soundstage. Podcasts on Overcast sounded clear and natural. Furthermore, the Nothing X app's EQ presets cover most listening preferences — the "Balanced" preset reduced bass emphasis for more neutral vocal reproduction. For comparisons on how budget earbuds handle sound signatures across price brackets, our JBL vs Soundcore tested side by side review provides useful context.

CMF Buds Pro 2 ANC Performance Test — Does -45dB Hold Up?

The CMF Buds Pro 2 ANC performance test across subway commuting, open-plan office, and outdoor environments revealed a consistent pattern: strong for everyday environments, limited in extreme noise. -45dB is a marketing ceiling, not a consistent real-world measurement. However, the ANC genuinely performs above the $60 baseline — particularly in office environments where it exceeded my expectations.

On the London Underground, ANC reduced carriage ambient noise to a manageable background hiss. Podcast dialogue became clearly audible at 55% volume — versus 75% needed without ANC. I also compared the CMF Buds Pro 2 directly against the EarFun Air Pro 3 ($79) on the same journey. Both performed similarly in transit noise reduction. For $20 less, that near-parity surprised me significantly.

Transparency mode passes ambient sound naturally enough for conversations and street safety. It adds a slight electronic character at high ambient volumes — typical for earbuds at this price. Wind at walking pace causes noticeable ANC disruption, which is a consistent limitation across budget ANC earbuds. Additionally, the adaptive ANC switches between indoor and outdoor modes automatically, which occasionally creates brief mode transitions during commuting. Setting ANC to manual mode in the CMF app prevents this.

CMF Buds Pro 2 Battery Life Test — 10 Hours Reality Check

The CMF Buds Pro 2 battery life test produced reliable results. At 60% volume with ANC off, I measured 9.4 hours — close to the rated 10h figure. With ANC active, the measured result was 6.8 hours versus the rated 7h. Both figures hold close to TOZO's stated specifications — strong accuracy for a $60 earbud.

LDAC battery drain is worth noting specifically. With LDAC active (versus AAC) and ANC on, battery consumption increased noticeably — approximately 15–20% more drain in testing. Therefore, Android users running LDAC full-time with ANC should expect closer to 5.5–6 hours realistically. This trade-off is worth knowing before purchase.

What surprised me: the quick charge speed. Ten minutes in the case added approximately 1.5 hours of ANC-on playback — enough for most commute catch-up scenarios after a forgotten overnight charge. Furthermore, the battery indicator in the Nothing X app shows both earbud and case percentages accurately — a detail that many $60 earbuds skip or approximate poorly.

Gaming Mode and Low Latency — Does 45ms Actually Work?

The CMF Buds Pro 2 gaming mode reduces Bluetooth latency to approximately 45ms — a significant improvement over standard AAC's approximately 80ms. I tested gaming mode on PUBG Mobile and Genshin Impact on a Samsung S24 over three sessions. Audio cues landed noticeably tighter. Footsteps and direction audio felt more responsive in competitive play.

However, gaming mode's benefits extend beyond games. Video streaming in gaming mode reduces the lip-sync drift that standard SBC causes at ~150ms. Watching Netflix with gaming mode active produced imperceptible sync throughout two full film screenings. Consequently, I used gaming mode for all video content during the test period, not just gaming.

The limitation: gaming mode isn't available simultaneously with LDAC. Enabling gaming mode forces the codec down to SBC for the latency reduction. Therefore, audio quality in gaming mode is noticeably less detailed than LDAC listening. For casual mobile gaming and video streaming, the trade-off is worthwhile. For music-focused LDAC listening, keep gaming mode off. For budget multipoint options that also handle gaming use cases, our budget earbuds with multipoint guide covers relevant alternatives.

CMF Buds Pro 2 Call Quality Test — Zoom and Outdoor Calls

The CMF Buds Pro 2 call quality test across 10 indoor Zoom sessions and 5 outdoor walking calls produced a split result — good indoor and weak outdoor. The 6-microphone array handled quiet desk environments well. Callers consistently reported clear, present voice quality throughout the indoor Zoom test sessions with no notable background noise pickup.

Outdoors in moderate wind, the microphones over-processed. My voice became thinner and more synthetic-sounding. Callers reported "slightly robotic" quality on 3 of 5 outdoor walking calls. This is the most common limitation of aggressive noise reduction on budget earbuds — the CMF Buds Pro 2 is not exempt. Furthermore, in open-plan office environments, the microphone picked up nearby conversations more than callers preferred during louder sessions.

For professional Zoom users who primarily call from a home office, call quality is more than adequate. For people who regularly take outdoor calls in wind or busy streets, consider the limitations seriously.

CMF Buds Pro 2 vs Nothing Ear (a) and Competitors

The CMF Buds Pro 2 vs Nothing Ear (a) comparison is the most relevant for most buyers — both are Nothing-family products at a $39 price gap. The Nothing Ear (a) wins on sound signature refinement, long-wear comfort, and outdoor ANC consistency. The CMF Buds Pro 2 wins on LDAC support and the dual driver architecture that the Ear (a) lacks.

Against the EarFun Air Pro 3 at $79, the CMF Buds Pro 2 adds LDAC and dual driver for $20 less — while slightly conceding on ANC consistency and battery life. Against the Soundcore Liberty 4 NC at $79 (which also has LDAC), the CMF adds the dual driver and gaming mode at $20 less.

CMF Buds Pro 2 for Working From Home — 5-Day Desk Test

CMF Buds Pro 2 for working from home performed strongly for 5 consecutive days of WFH use. Multipoint connection between my Pixel 7 Pro and MacBook Pro 14" worked reliably — audio switched automatically between devices with an average 2.4 second switching time. ANC in indoor mode covered home distractions (street traffic, flatmate noise, HVAC) effectively enough to focus throughout the workday.

Battery across the WFH week with ANC active and LDAC on covered 5.8 hours of daily use — which didn't reach end-of-day on heavy-use days. I recharged in the case for 20 minutes mid-afternoon twice during the test week. Without LDAC, ANC-on battery extended to approximately 6.8 hours — covering full 8-hour days more reliably. The choice between LDAC quality and full-day battery is the key WFH trade-off on the CMF Buds Pro 2.

The honest WFH limitation: ear fatigue at the 3-hour mark during continuous sessions. The CMF by Nothing earbuds use standard silicone tips — switching to aftermarket foam tips (Comply Foam T-400 series, ~$10) extended comfortable wear by approximately 2 hours during testing.

Is CMF Buds Pro 2 Good for Commuting? — Transit Test

Is the CMF Buds Pro 2 good for commuting? For most urban commuters, yes — the ANC handles subway and bus ambient noise adequately, LDAC delivers the best possible audio during transit, and IPX5 handles sweat and rain. The battery covers a week of daily commutes (approximately 45–60 minutes each way) without needing a case charge mid-week.

The CMF Buds Pro 2 for commuting does have one practical nuance worth knowing. The transparent case is slightly larger than average compact TWS cases — it doesn't fit as discretely in a shirt pocket as the EarFun Air Pro 3 case. For jacket or bag carry, it's not an issue. Additionally, the touch controls work reliably in all weather during outdoor transit — no false triggers from rain or cold-gloved fingers in testing.

CMF Buds Pro 2 Review — Is It Worth It?

CMF Buds Pro 2 review conclusion on whether it's worth it depends on three specific buyer profiles — each with a clear answer.

Android user who wants LDAC + ANC under $65 → Yes, buy it. No other earbud at $60 combines dual driver audio, LDAC, -45dB ANC, gaming mode, and multipoint. The value combination is genuinely unmatched at this price. LDAC makes an audible difference via the planar tweeter, and ANC performs above the budget baseline.

iPhone user who wants the best $60 earbuds → Maybe, but consider alternatives. LDAC doesn't negotiate on iOS — you get AAC at best, which removes the primary audio quality advantage. For iPhone users, the EarFun Air Pro 3 at $79 or Soundcore Life A3i at $45 offer more relevant feature sets. See our best earbuds for iPhone under $100 guide for iOS-optimised options.

Buyer considering stretching to Nothing Ear (a) at $99 → Depends on priorities. If you primarily listen to music on Android and LDAC matters, save the $39 and get the CMF Buds Pro 2. If you wear earbuds 6+ hours daily and comfort is paramount, the extra $39 buys meaningfully better long-wear design on the Nothing Ear (a).
