They are clip-type, which clips onto the earlobe from the side, so anyone can wear them the same way, regardless of the shape of their ears. Because the ear canal is not completely blocked, you can hear the surrounding sounds, pay attention to your surroundings while listening to music, and also talk to people. [No In-Ear Design] Completely wireless Bluetooth earphones with an ergonomic and comfortable design, no ear shape, no in-ear, and no pain when worn. Noise reduction function, dual-microphone design, and ENC noise reduction effect allow for clear calls, just like face-to-face communication. [Smart Touch] Fully wireless earphones with smart touch operation design, easy to operate, and can control volume adjustment/music playback/pause, call/hang up/reject/next/previous/Siri activation, etc. [Compatibility] Ear clip earphones can be used with all Bluetooth-enabled devices such as iPhone, Android, and laptops. They are lightweight headphones that you'll forget you're wearing. There is still a battery that allows you to listen to music continuously for 3-4 hours. When the charging case is attached, the binaural playback time is up to 25 hours. [Bluetooth 5.3] Bone conduction earphones adopt Bluetooth 5.3 chip, which greatly improves sound quality and connection convenience compared to conventional wireless headphones.
