The physical revision code is not proven for this sales SKU. Original guide B172, a 2025 declaration B187, and currently linked B195 declarations are not silently mapped to it.9Maker spec sheet (PDF)cdn.shopify.com/s/files/1/0376/5420/0459/files/CMF_Buds_Pro_2_EU_DoC_Multilingual.pdfRead 8 October 2026Current family-linked declaration prints B195, software V1.0.1.33, signed August 17, 2026. Family PSTI likewise prints B195. A 2025 declaration prints B187, while the downloadable user guide prints B172. None supplies an exact bridge to the selected current US sales SKU, so physical model-code mapping and revision-specific certifications remain unknown.

Feature Needs Android and iOS compatibility Current listing specifies Android 6.0 or above and iOS 13 or above. Some older family FAQ wording says Android 5.0. LDAC audio Use a compatible LDAC source and enable high-quality audio in Nothing X. Up to 24-bit/96 kHz is a codec claim, not lossless playback. Current physical-revision support for simultaneous LDAC and Dual Connection or Dirac is not established. Spatial Audio Effect Enable HRTF spatial processing in Nothing X. No specific source format or dynamic head tracking is claimed. Smart Dial on the case Configure the case dial in Nothing X. It supports volume, playback, noise-mode, voice-assistant, low-lag and mic-mute commands. Case-only mute does not establish on-ear microphone mute. Earbud volume controls Assign double tap and hold in Nothing X Controls. Hold after the double tap to change volume. Case dial rotation is a separate option. Source2Maker product pageus.nothing.tech/products/cmf-buds-pro-2Read 8 October 2026Current Android minimum is 6.0 and iOS minimum is 13. Generic older FAQ says Android 5.0.

- Charging guidance
- Current maker table claims 60 minutes to fully charge earbuds in the case and 85 minutes for the charging case and earbuds together by USB-C. The historical family page claimed 70 minutes for the combined set. No current empty-case full-charge duration is established. The headline claims up to seven hours after a ten-minute charge, without clearly identifying its earbud-only or case-inclusive scope. It is not assigned to the earbuds-only quick-charge field. A cable is omitted from current new-sale box lists, while transitional retailer stock may still include one. Generic CMF Buds disclaimer figures on the page do not match this Pro 2 table and are not substituted.2Maker product pageus.nothing.tech/products/cmf-buds-pro-2Read 8 October 2026Current US table names 85 minutes combined, versus the historical 70-minute family claim. The page also contains generic CMF Buds disclaimer text about 35.5-hour playback, two microphones per bud and other charge times that conflicts with the exact Pro 2 table. Those generic statements are not used as Pro 2 numeric facts. No charger input wattage or case-only duration is inferred.
