The natural sound quality resonates comfortably in your ears. ■【Newly Designed Sleep Earphones: Eliminating the "Painful to Wear While Sleeping" Problem】 Innovative ergonomic design: The shark fin-like ear hook design fits snugly in the ear and doesn't easily fall out, so it won't come loose even when worn during sleep. Furthermore, it's made of soft material and shaped to be less painful to the ears when lying down, perfectly fitting the ear canal and allowing you to sleep freely without feeling uncomfortable pressure. You can wear it for long periods without discomfort, and it effectively blocks out surrounding noise in noisy environments such as sleep, travel, study, work, subways, airplanes, trains, and buses. ■【Lightweight Design for Comfortable Wear】 The small in-ear design doesn't put a burden on your ears even when lying down. Weighing only 10g, it's easy to carry around. ■【Improved "No Sound Due to Disconnection" Problem】 Have you ever felt stressed when your earphone cable gets pulled or tangled while enjoying music? To solve this problem, these sleep earphones add a tough material to the cable, making it less likely to tear. Also, the soft cable is less likely to tangle and prevents shorts and disconnections. ■【Remote Control Function】 These sleep earphones are equipped with a remote control function, allowing you to control volume adjustment, answer/end calls, skip to the next/previous song, and play/pause. This is very convenient because you can easily operate the remote control buttons on the earphones while keeping your smartphone at hand.
