Overview

The Beats Fit Pro, released in 2022, is a true wireless earbuds featuring Apple’s H1 chip. Characterized by excellent fit stability through flexible wingtip design, it supports active noise cancellation and spatial audio. With IPX4 sweat resistance suitable for sports applications, it delivers balanced sound quality through proprietary 9.5mm transducers. Currently priced around 19,000 yen, it positions itself as a cost-performance focused model, approximately 6,000 yen cheaper than Apple’s genuine products.

Scientific Validity

\[\Large \text{0.6}\]

Professional measurement analysis shows good weighted harmonic distortion (THD) performance, with a sharp peak between mid-low to high frequencies that remains difficult to detect in real-world content due to its narrow affected frequency band. The 9.5mm proprietary transducers achieve excellent frequency balance, providing clear vocal reproduction despite a V-shaped sound profile. Adaptive noise cancellation automatically adjusts to environmental conditions, effectively blocking bus engine low-frequency noise. However, it falls short of Bose-level sound isolation performance, showing limited effectiveness during train use. Overall acoustic transparency meets industry standards, though measurable objective improvement effects remain moderate.

Technology Level

\[\Large \text{0.6}\]

Apple H1 chip integration achieves Class 1 Bluetooth connection stability and low latency, providing solid technical foundation. Dual beamforming microphones with digital processor wind noise suppression represent advanced design, though actual call quality tends toward thin, dark, and muffled voice reproduction. The design utilizing 3 microphones for single-ear and 5 microphones for dual-ear use is technically superior, but background noise separation performance remains limited. Adaptive ANC system features real-time adjustment capabilities but doesn’t reach industry-leading noise cancellation performance. Flexible wingtip fit stability represents practical technical innovation, though direct contribution to acoustic performance improvement is limited.

Cost-Performance

\[\Large \text{0.6}\]

Against the current market price of 19,000 yen, comparable functionality products include Soundcore Liberty 5 (14,990 yen, 32-hour battery, ANC, app support) and Anker Soundcore Life P3 (8,990 yen, 35-hour battery, ANC, customizable EQ). While Apple H1 chip connection stability and spatial audio support provide differentiation factors, basic acoustic performance and ANC functionality show no decisive advantages justifying the price difference. Comparison with AirPods Pro (2nd generation) shows approximately 6,000 yen price difference with limited audio quality differences. CP = 14,990 yen ÷ 19,000 yen = 0.79, indicating relatively good price competitiveness.

Reliability & Support

\[\Large \text{0.5}\]

IPX4 sweat resistance handles exercise sweat and light water splashes but doesn’t support underwater use due to non-waterproof design. Apple/Beats brand quality control maintains standard levels, though 1-year warranty period remains at industry standard. Battery life of 6 hours (ANC enabled) performs as advertised, but long-term battery degradation data is limited. Firmware updates are provided through Apple ecosystem, though Android usage shows lower update frequency. Repair services are available through authorized dealers, but regional variations may cause extended repair periods.

Rationality of Design Philosophy

\[\Large \text{0.5}\]

Design philosophy emphasizing sports applications and Apple ecosystem integration is clear, with wingtip fit stability matching intended purpose. However, against the 19,000 yen price point, smartphone + external DAC solutions show limited audio quality advantages. Apple H1 chip adoption contributes to connection stability improvements, but differences from equivalent general-purpose Bluetooth chips remain minimal at practical usage levels. Specialized device necessity primarily depends on Apple ecosystem convenience, raising rationality questions from pure acoustic performance improvement perspectives. Microphone performance limitations result in insufficient business call quality, presenting design philosophy consistency challenges.

Advice

Beats Fit Pro suits users primarily within Apple ecosystem who prioritize exercise fit stability. Wingtip design provides excellent fit comfort that resists displacement during intense activity. Audio quality delivers bass-focused balanced sound sufficient for general music listening. However, against the 19,000 yen price point, call quality and noise cancellation performance may fall short of expectations. Particularly for business-focused calling, consider alternative options. Within the same price range, Nothing Ear (14,800 yen, transparent design, ANC) and Soundcore Liberty 5 (14,990 yen, 32-hour battery, ANC) offer superior price-performance ratios. These alternatives merit consideration for users not prioritizing Apple product integration.
