These tables were decoded as source data without executing scripts or accessing a private API. Current claims belong to this selected sales listing, without asserting an independently tested physical revision.","bluetooth_version":"Current US table explicitly states Bluetooth 5.4. Generic support FAQ and original B172 documents say 5.3. Current listing is represented, with the historical conflict retained. No firmware-only radio upgrade or physical revision code is invented.","drivers":"Current table names an 11 mm bass driver and 6 mm micro-planar tweeter. Dual-driver acoustics establishes one of each per earbud. The maker does not explicitly name the magnetic architecture or bass transducer technology, so type cells and the aggregate driver_type are left unknown.","driver_diaphragm_material":"Current Sound table publishes two diaphragm descriptions alongside the two named driver rows. Material text retains their bass/tweeter order and the exact micro-planar description. No original-review driver architecture is imported.","anc_claimed_attenuation_db":"Current maker names up to 50 dB Hybrid ANC with coverage up to 5000 Hz. Its footnote calls 50 dB a theoretical laboratory maximum. Coverage up to 5000 Hz does not establish the frequency at which maximum attenuation occurs. No reviewer-measured overall attenuation is substituted.","anc_adaptive":"Current maker describes automatic detection and compensation for ear-canal noise leakage, plus environment-adaptive mode in Nothing X. This does not prove real-time adaptive EQ.","microphone_count":"Current Call functions table states six microphones in total across the pair. They serve voice capture. Shared ANC functions do not add microphones.","microphone_count_total":"Six total microphones across the earbud pair, counted once. Current table calls the call processing Clear Voice Technology 3.0 and wind processing Wind Noise Reduction 3.0, while other page text retains 2.0 wording. Processing-version conflict does not create extra physical microphones.","battery_capacity_mah":"Current battery table explicitly 60 mAh for one earbud. Typical or rated capacity is not stated.","case_battery_capacity_mah":"Current battery table explicitly 460 mAh for the case. Input current and output capacity are not substituted.","charge_time_0_100_min":"Current table explicitly full charge with charging case: 60 minutes, earbuds only. The separate 85-minute number is for the charging case and earbuds together, not an empty-case charge.","charging_notes":"Current 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.","max_sample_rate_khz":"Current LDAC section directly states up to 24 bits/96 kHz/990 kbps with a compatible LDAC source. This does not establish lossless playback.","max_bit_depth_bits":"Direct current LDAC claim, conditional on a compatible source and enabled codec. Not inferred from Bluetooth version.","virtual_surround":"Current maker explicitly names Spatial Audio Effect based on HRTF. No Dolby format, dynamic head tracking or object-audio decoding is inferred.","weight_g":"Current Buds design table explicitly one-bud mass 4.9 g. Tip size is not stated. This is a maker claim, not a reviewer weight measurement.","dimensions_mm":"Current Buds design table explicitly labels height 33.1, width 20.2 and depth 23.8 mm. Axis labels are retained without reordering by appearance.","case_dimensions_mm":"Current Case design table explicitly height and width 53.4 mm, depth 23 mm.","case_weight_g":"Current Case design table gives 46 g separately from the one-bud 4.9 g figure. No case-inclusive total is used.","in_the_box":"Current table lists earbuds, S/M/L tips, charging case, safety/warranty information and user guide. Specific maker note says cable omitted from new sales starting May 15, 2025, with transitional retailer stock potentially retaining a cable. No cable is treated as a current standard item and no blanket absence is asserted for every stock revision.","feature_requirements":"Current Android minimum is 6.0 and iOS minimum is 13. Generic older FAQ says Android 5.0. Current table is used without claiming all advanced functions operate identically across platforms. Case Smart Dial requires configuration in Nothing X and includes microphone mute. It does not establish an earbud mic mute control.","frequency_response_hz":"Current maker acoustic comparison explicitly labels Buds Pro 2: 20~40000Hz. This is the earbud frequency range, not inferred from the LDAC sample rate.","battery_life_claimed":"Current battery table states 11 hours earbuds-only and 43 hours with case for ANC off, matching the model-specific FAQ. A page-body sentence instead says ten hours from the 60 mAh earbud. The specified table/FAQ claim is represented with that body conflict explicit, without claiming a rounding method or tested revision.","wind_noise_reduction":"Current Call functions table explicitly names Wind Noise Reduction 3.0, so this is call-processing evidence. Other page prose retains 2.0 wording. No separate user-selectable listening/ANC wind toggle or physical wind-mesh design is inferred.","compatible_platforms":"Current features table lists Android and iOS with minimum Android 6.0 and iOS 13. Bluetooth audio route only. Console, PC and Mac support is not stated.","platform_connections":"Both mobile systems connect over Bluetooth per the Android and iOS features row. Microphone behaviour per platform is not stated, so microphone_works is left out.","voice_assistant":"Nothing X app section: \"Use Buds Pro 2 to call up ChatGPT from your CMF and Nothing phones.\" The original user guide lists wake up voice assistant as an optional earbud function without naming an assistant."}},{"url":"https://support.nothing.tech/hc/en-us/articles/26468752574481-What-audio-formats-does-CMF-Buds-Pro-2-support","kind":"manufacturer_page","accessed":"2026-10-08","fields":["bluetooth_codecs"],"notes":{"bluetooth_codecs":"Current exact-model support answer explicitly lists LDAC, AAC and SBC.
