[Popular Model with Specialized Noise Cancellation] The EarFun Air Pro 4i, an evolution of the popular EarFun Air Pro 4, features Hybrid ANC and proprietary QuietSmart 3.0 ANC technology. It effectively blocks out ambient noise with up to 50dB of noise reduction. Adaptive ANC automatically adjusts noise reduction based on ambient conditions and fit for a natural, less oppressive sound. Furthermore, optimized filters for each frequency band and a feedback microphone positioned closer to the eardrum improve noise detection and cancellation accuracy. The improved vent design stabilizes air pressure balance for sustained sound isolation. This new standard in noise cancellation promises clear sound and a comfortable fit in any situation. Note: Noise cancellation effectiveness varies depending on the fit of the earphones. For maximum noise cancellation, ensure the earphones fit snugly in your ears. [11mm Titanium Diaphragm x LDAC for Hi-Res Audio Playback] The 11mm titanium-coated composite diaphragm driver delivers high rigidity and fast response, faithfully reproducing the original sound. It delivers a balanced sound with clear highs, rich mids, and deep bass. LDAC compatibility delivers high-resolution wireless sound quality and has earned Hi-Res certification from the Japan Audio Society. Furthermore, 3D sound technology delivers a three-dimensional sound experience with clear instrument and vocal positioning. Enabling "Theater Mode" puts you in the center of a live music venue. Note: LDAC is not available in Theater Mode or multipoint connection. [Clear Calls with 6 Microphones + AI Technology & IP55 Dustproof and Waterproof] Enjoy clear conversations during meetings and phone calls.

[Ultimate sound quality and comfort achieved through shape and materials] The oval-shaped sound tube is larger and shorter, reducing sound dispersion and concentrating the sound direction, resulting in high sound quality and excellent noise cancellation. The earpieces feature a dual-hardness design, with silicone of different hardness used for the earbuds and shafts. The shafts are made of a harder material, firmly securing the base and ensuring bass is delivered to the eardrum. The thinner earbuds ensure compatibility with various ear canals and excellent wearing comfort. In addition, the earpieces feature a unique design with a circular outer surface and an oval inner surface. In addition to structural innovations that take sound quality into consideration, they also provide a comfortable fit and a tight seal.
