PRODUCT DESCRIPTION
Ergonomic Clip-On Ear-Cuff Design & Pressure-Free Comfort
The UGREEN HiTune S3 adopts an open-ear clip-on design that securely sits on your ear but leaves your ear canal unobstructed. Thanks to the memory nickel-titanium alloy material used in the construction, every earbud weighs only 5.3 grams and has a silicone coating for skin-friendliness. As a result, it eliminates pressure build-up on ears and complications associated with the use of regular ear tips, whilst keeping you aware of your surroundings, when jogging outdoors or cycling.
Directional Sound Acoustics and 12mm Dynamic Drivers
With 12mm custom-made dynamic acoustic drivers installed, the HiTune S3 is capable of producing highs nature of sound, intricate mid end sounds, and bass. Directional sound technology has been identified and applied in order to resolve the problem of sound bleeding from the open-ear type of earphones and to deliver sound waves straight to the ear canal while preventing external sound from leaking by about 98%.
AI Call Noise Cancellation, Bluetooth 5.4, 30-Hour Battery Life
With Bluetooth 5.4, HiTune S3 allows for quick pairing, reduced power consumption, and a reliable wireless range of up to 10 metres. The HiTune S3 utilizes the dual microphones which combined with AI ENC technology provide a good level of separation between human voice and noise. The total battery capacity reaches 30 hours, while a single charge of the unit is enough for approximately 7.5 hours of use. Additional features include a low latency mode intended for gaming, which works in just 0.06 seconds, and IPX5 protection against water and sweat.
