CMF Buds Pro 2
True wireless earbuds achieving dual-driver (11mm+6mm), LDAC support, and 50dB noise canceling at 80 USD. Features Smart Dial physical volume control and exceptional functionality for the price range, though retains some V-shaped sound signature coloration.
Overview
The CMF Buds Pro 2 are true wireless earbuds from Nothing’s sub-brand, CMF, featuring a dual-driver configuration (11mm dynamic + 6mm planar tweeter) at an 80 USD price point. The combination of a titanium-coated 11mm driver and a 25μm ultra-thin 6mm planar tweeter aims for wideband reproduction, from rich bass to delicate treble. It supports the LDAC codec for hi-res audio, offers powerful hybrid ANC up to 50dB, and includes distinctive features like a Smart Dial for physical volume control, 43-hour total playback, IP55 water resistance, and ChatGPT integration. This package delivers remarkable functionality for its price range.
Scientific Validity
\[\Large \text{0.7}\]The CMF Buds Pro 2 pursues wideband faithful reproduction with its dual-driver configuration of an 11mm dynamic driver and a 6mm planar tweeter. LDAC support enables data transmission up to 990kbps, which is about three times the information capacity of conventional SBC (328kbps). The hybrid ANC claims up to 50dB of noise reduction. If third-party measurements confirmed this reduces low-frequency noise by approximately 81%, it would be considered excellent performance. However, in terms of frequency response, it is said that SoundGuys measurements confirmed a significant bass emphasis of about 12-15dB in the 20-400Hz range. This is a major drawback from a high-fidelity perspective. While its ANC performance is high, the significant sound coloration prevents it from reaching ideal scientific transparency.
Technology Level
\[\Large \text{0.8}\]The technological standard of the CMF Buds Pro 2 is extremely high, considering its 80 USD price. The dual-driver configuration, especially the adoption of a 25μm ultra-thin planar diaphragm, is technically advanced and typically found in products costing 200 USD or more. The integration of multiple sophisticated technologies like the LDAC codec, hybrid ANC, and multipoint connection at a low price is highly commendable. Furthermore, the Smart Dial physical volume control mechanism is an innovative and rational design that avoids the malfunctions of touch controls. With other features like titanium-coated drivers for rigidity and lightness, and six microphones for improved call quality, its overall technology integration level is among the top tier in the industry. However, it centers on the effective combination of existing technologies rather than proprietary developments.
Cost-Performance
\[\Large \text{0.8}\]At 80 USD, the CMF Buds Pro 2’s cost-performance is not absolute. When compared to other products with key features like LDAC, ANC, and multipoint connection, a cheaper alternative exists: the SOUNDPEATS Capsule3 Pro (around 60 USD). The cost-performance calculation is 60 USD ÷ 80 USD = 0.75, indicating that its price advantage is limited when looking at functionality alone. However, the true value of this product lies in achieving a “dual-driver configuration with a planar tweeter” at this price point. Products with this specific configuration are typically sold for 150 USD or more. For users seeking a unique acoustic experience, it remains a high-value option.
Reliability & Support
\[\Large \text{0.6}\]As a brand under Nothing established in 2022, CMF is an emerging company with a limited long-term reliability track record. The product comes with a one-year warranty, which is the industry standard. Its IP55 water resistance ensures durability for daily use, but data on long-term battery degradation rates or specific failure statistics are not publicly available. Theoretically, a dual-driver configuration could have a higher risk of failure than single-driver products. Firmware update support is implemented, but the frequency of updates and long-term support continuity are uncertain. While its price competitiveness is high, its reliability and support systems are still developing compared to established brands like Anker or Sony.
Rationality of Design Philosophy
\[\Large \text{0.6}\]The design philosophy of the CMF Buds Pro 2 is to “provide advanced features at an extremely low price.” The division of labor between a planar tweeter for high-frequency extension and a dynamic driver for bass reproduction is acoustically rational. The adoption of the Smart Dial for physical control is an innovative and commendable attempt to solve the usability issues of touch controls. However, there are trade-offs between price and performance, such as a strong V-shaped sound tuning that is irrational from a high-fidelity perspective and a manufacturing strategy focused on cost reduction. The emphasis on practical features like multi-functionality and long playback time comes at the expense of sonic purity, a challenge inherent in this product’s design philosophy.
Advice
The CMF Buds Pro 2 is an optimal choice for users wanting to experience a unique “planar tweeter dual-driver” configuration in the sub-100 USD range. It offers an acoustic experience aimed at balancing delicate highs and rich bass, which is unparalleled at this price point. LDAC support will appeal to Android users, and the Smart Dial physical control is a strong selling point for those who want to avoid accidental touch activations. However, if functionality is the top priority and you’re looking for LDAC and ANC at a lower price, the SOUNDPEATS Capsule3 Pro (around 60 USD) is a strong competitor. Furthermore, due to the strong bass emphasis shown in measurement data, it is unsuitable for music that requires a flat frequency response, such as classical or jazz. This is an innovative product highly recommended for the technologically adventurous user seeking acoustic value that exceeds its price.
