EarFun

【Noise-Canceling Enhanced Version of Popular Model】The EarFun Air Pro 4i, an evolution of the popular EarFun Air Pro 4, features hybrid ANC and EarFun's proprietary QuietSmart 3.0 ANC technology. With a maximum noise reduction capability of 50dB, it effectively cuts out ambient noise. Adaptive ANC automatically adjusts the strength of noise reduction according to the surrounding environment and wearing condition, resulting in a natural sound with less pressure. Furthermore, filters optimized for each frequency band and feedback microphones positioned close to the eardrum improve the accuracy of noise detection and removal. Improved ventilation design stabilizes air pressure balance, maintaining sound isolation performance. This is a new standard in noise cancellation, promising clear sound and comfortable wear in any situation. Note: Noise cancellation effect varies depending on the degree of fit. To achieve maximum noise cancellation, please ensure the earphones are securely fitted to your ears.

【11mm Titanium Diaphragm x LDAC for High-Resolution Audio Playback】The 11mm diameter titanium-coated composite diaphragm driver faithfully reproduces the original sound with high rigidity and fast response. It expresses clear highs, rich mids, and deep bass in a well-balanced manner. LDAC compatibility achieves high-resolution wireless sound quality and has obtained Hi-Res certification from the Japan Audio Society. Furthermore, 3D sound technology allows you to experience a three-dimensional sound with clear localization of instruments and vocals. Enabling "Theater Mode" allows you to enjoy an immersive experience as if you were in the center of a live concert. Note: LDAC cannot be used in Theater Mode or with multipoint connection.

【Clear Calls with 6 Microphones + AI Technology & IP55 Dustproof & Waterproof】Whether in a meeting or on a call, you can have clear conversations—EarFun Air Pro 4i is equipped with six high-performance microphones that capture voice from 360°. AI technology detects ambient noise and effectively removes surrounding noise. Enjoy clear voice calls that ensure your voice is transmitted clearly to the other party. Furthermore, with IPX55 dust and water resistance, you can rest assured that it will withstand accidental spills and sweat during exercise. Note: The charging case is not waterproof.

[Up to 40 Hours Playback & Multipoint Connection & Earphone Tracking] Enjoy up to 9.5 hours of music on a single charge, and a total of 40 hours with the charging case. Fast charging allows for 2 hours of playback with just a 10-minute charge, perfect for busy mornings. Wireless charging is also supported, so simply place the earphone on the charging case for quick and easy charging. Multipoint connection is also supported, allowing simultaneous connection to two devices. Android devices can be paired quickly using Google Fast Pair. In addition, you can find your earphones by making them emit a sound using the EarFun Audio app's "Find My Earphones" function, and they also support location tracking with the latest Android Find Hub tracker. Never worry about losing your earphones again!

[Shape and materials designed for ultimate sound quality and comfort] The oval-shaped sound tube is designed to be larger and shorter, which reduces sound dispersion and concentrates the direction of the sound, resulting in high sound quality and excellent noise cancellation. The eartips have a dual-hardness design, using silicone with different hardness levels for the umbrella and shaft. The shaft uses a harder material to firmly fix the bass, allowing it to transmit low frequencies to the eardrum without loss. The umbrella part is designed to be thinner, achieving a wider range of ear canal compatibility and superior wearing comfort. Furthermore, the eartips adopt a unique design with a circular outer surface and an oval inner surface. In addition to structural considerations for sound quality, this also achieves comfort a
