Pocket-sized & Up to 36 Hours of Continuous Playback This product has undergone multiple structural adjustments and uses a 60° angle to achieve the ideal golden ratio, ensuring a comfortable fit. Weighing only 4g per earbud, it doesn't cause the pressure and stuffiness of in-ear types, so your ears won't get tired even after long periods of wear. The charging case is only 26mm thick, making it easy to slip into your pocket. Its small and lightweight design makes it easy to carry around and won't interfere with your fashion. With its incredibly low power consumption, it offers ultra-long usage. The earbuds can provide approximately 4-6 hours of continuous calls/music playback on a single full charge, and with the charging case, you can enjoy a total of up to 36 hours of use. Top-Class Sound Quality & Instant Pairing Equipped with a 13mm liquid crystal polymer composite diaphragm and supporting the high-quality AAC codec, it delivers clear high frequencies, high-resolution mid-range frequencies, and deep low frequencies, allowing you to enjoy balanced, high-quality stereo sound across all frequency ranges. It also features the latest CVC8.0 noise-canceling technology to reduce noise. Simply opening the charging case lid turns on the power and automatically enters pairing mode. It has automatic memory, allowing for instant connection from the second time onwards, eliminating the need for complex operations. Independent Left/Right Earbuds & Hands-Free Calling & Multifunctionality Either the left or right earbud can be connected to your smartphone separately. As separate left/right Bluetooth earbuds, you can use both ears, or just one. Furthermore, it has a built-in microphone that captures your voice clearly. With the external sound capture function, you can have conversations while wearing the earbuds, and even in crowded places, you can easily hear the voice of the person you're talking to, enabling clear calls. You can also call up a voice assistant and control it with your voice, as well as perform basic functions such as music playback and pause, call start, end, reject, next song, and previous song. The physical buttons on the earbuds themselves provide a smart design.
