ACMF Buds Pro 2

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.

Low latency mode	The product page footnote lists the Xiaomi 14 Ultra, Xiaomi 14, Xiaomi 13, Xiaomi 13 Pro, Xiaomi 13 Ultra and POCO F6 as models that support low latency and says more models are being adapted. The support FAQ says it turns on by holding the touch area of both earbuds for 1.5 seconds outside calls, or in the Xiaomi Earbuds app.
Google Fast Pair	Android devices with Google Play services 11.7 or later, which covers Android 6.0 and later. Fast Pair switches off for 5 minutes after three cancelled attempts.
Xiaomi Earbuds app	Android 6.0 or later (app version 1.20.0i or later) or iOS 14.0 or later (app version 1.11.0 or later). Touch control settings are only available in the app.
Pop-up with battery levels	Only some Xiaomi phones with Pair compatible devices turned on in the Bluetooth additional settings.
10-minute fast charge for 3 hours of music	The charging case needs at least 35 percent battery.

Charging guidanceiPublished charging guidance or estimates that do not separate earbuds and case. Preserve the maker’s component scope and limits. Do not assign an unspecified or combined estimate to a component-specific numeric field.

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.

Charging case input is 5 V 800 mA max and output is 5 V 340 mA max. The earbuds take 5 V 170 mA max. A fully charged case recharges the earbuds about 3.5 times. A charging cable is not in the box.
