The CMF Buds 2 are not a new launch. Nothing introduced them in India in April 2025 at ₹2,699, and the earbuds have been available since. Nothing’s product page shows the Light Green colour option, which was already part of the original colour lineup. Current prices and stock may vary by seller.
The gap between the spec sheet and what a pair of budget earbuds delivers in practice deserves scrutiny. Nothing’s official page lists 48dB hybrid ANC, an 11mm PMI driver, spatial audio, and up to 55 hours of total playback with the case. Each figure carries conditions that buyers should understand before making a purchase.
What the 48dB ANC Claim Actually Means
Nothing’s official product page carries a footnote many buyers may miss. The 48dB figure is a theoretical maximum measured in Nothing’s labs, and real-world noise reduction will vary by environment. It is standard industry practice, but it does mean the headline number should be treated as a ceiling, not a guarantee.
So what does this actually mean for a commuter? One independent review found that the ANC blocked much outdoor noise, although it could feel less effective in louder surroundings. At the ₹2,699 launch price, that is a reasonable trade-off.
Battery Life: Read the Conditions, Then Read Them Again
The headline 55-hour playback estimate carries conditions: it requires disabling Active Noise Cancellation, setting the volume to 50%, using the AAC codec, and including the charging case. Nothing claims up to 13.5 hours for the earbuds alone with ANC off. With ANC on, the company lists up to 7.5 hours for the earbuds and up to 32 hours with the case.
One independent reviewer reported roughly six hours of playback on a single charge at 50% volume with ANC off. The reviewer did not fully test battery life with ANC on and estimated around three to four hours. That estimate should not be treated as a completed battery test.
The fast-charging claim is also conditional: ten minutes of charging is said to provide up to 7.5 hours of playback with the case when ANC is off.
The Spec Sheet, With Conditions Attached
| Feature | CMF Buds 2 (Official Claim) | Conditions Attached |
|---|---|---|
| ANC | Up to 48dB hybrid | Theoretical lab maximum; real-world performance varies |
| Driver | 11mm Polyetherimide (PEI) + Polyurethane (PU), Dirac Opteo | Standard for the price bracket |
| Battery (buds) | Up to 13.5 hours | Up to 13.5 hours with ANC off; up to 7.5 hours with ANC on |
| Battery (case total) | Up to 55 hours | Up to 55 hours with ANC off; up to 32 hours with ANC on |
| Fast charge | 10 min → up to 7.5 hours | With case and ANC off |
| IP rating | IP55 for the earbuds | The charging case is not rated for waterproofing |
| Microphones | 6 HD mics | Clear Voice 3.0 is designed for calls |
| Bluetooth | 5.4, dual-device | AAC/SBC codecs only; no LDAC |
One point of confusion: an Amazon India listing claims LDAC support for the Buds 2, while Nothing’s official support page lists only AAC and SBC. The company has not clarified the discrepancy.
The Comparison That Matters Most
At launch, the Buds 2 sat between the Buds 2a at ₹2,199 and the Buds 2 Plus at ₹3,299. The Plus offers 50dB ANC, a 12mm LCP driver, and LDAC support, with up to 61.5 hours of total battery life when ANC is off. The 2a steps down to 42dB ANC and a 12.4mm bio-fibre driver. Current selling prices may differ from those launch prices.
Whether the launch-price gap to the Plus is worth it depends on whether LDAC and stronger ANC matter to you. For buyers who prioritise battery life and acceptable ANC, the CMF Buds 2 remain a choice to consider alongside other budget wireless earbuds.
Among these three models, the Plus is the option with LDAC support. If the budget is absolute, the 2a is another option, subject to its current price and availability.
What One Cannot Verify
Independent reviews have tested the Buds 2, including one that published measurements of their noise cancellation. Those results use the reviewer’s own test conditions and should not be treated as a direct verification of Nothing’s theoretical 48dB ceiling.
The earbuds launched at ₹2,699. Their practical compromises become clearer when buyers look beyond the headline figures and check the conditions behind battery life, noise cancellation, and codec support.
