The following is quoted from a website: The fully wireless earphone market, which rapidly expanded around 2018, has grown with the spread of smartphones and tablets. After the COVID-19 pandemic, the demand has shifted towards "multi-purpose" use, not only for listening to music but also for watching videos and SNS, and as high-performance voice devices for meetings. Furthermore, with changes in lifestyle, "while-listening" earphones that can be used while doing chores like cleaning, laundry, and cooking, or during fitness and remote work, while incorporating ambient sounds, have become a notable trend. Especially, open-ear types that don't block the ears are gaining support for their comfort and safety. "JBL Sense Lite" is the standard model of JBL's open-ear fully wireless earphones. It uses ear hooks made of high-quality liquid silicone, also used in medical devices. Combined with shape-memory wire, it naturally fits various ear shapes. In addition, the 3D ergonomic design, based on ergonomics and thorough verification, achieves a "snug fit" that conforms to the curve of the ear. Along with a lightweight design of about 9.5g per side, it provides a comfortable listening experience even during long hours of use or when used with glasses. Furthermore, it is equipped with an 18x11mm dynamic driver and a bass boost algorithm, achieving rich bass and balanced sound. In addition, JBL OpenSound technology minimizes sound leakage, balancing consideration for surroundings with immersion. It also reproduces mid-high frequencies naturally and clearly, providing uncompromising sound quality despite being an open-ear type. It also features four beamforming call microphones, enabling clear calls even outdoors by suppressing noise. In addition, it supports up to approximately 32 hours of playback, and approximately 3 hours of playback with a 10-minute quick charge. Furthermore, it is equipped with various convenient features for daily use, including IP54 waterproof and dustproof performance, multi-point support, Google Fast Pair, dual connect, and the JBL Headphones app. Experience a new "while-listening" experience where music and daily life connect comfortably, created by the balance of comfort that doesn't block the ears and authentic JBL sound. ■ Weight: Earphone body approx. 9.5g each, charging case approx. 64.5g
