However, with bone conduction (ear cuff type earphones), sound vibrations are transmitted directly to the skull, allowing sound to be transmitted without going through the ear or eardrum. 【Doesn't put a strain on the ears】 The difference from conventional wearing methods is that wearing regular earphones for extended periods can cause itchy or painful ears, and in severe cases, can lead to "otitis externa" or "hearing loss," but this method can better protect the ears. 【Prevents sound leakage】 Equipped with excellent sound leakage protection, allowing you to fully immerse yourself in the world of music. 【Flexible ear hooks & IPX7 waterproof】 The ear hooks are flexible and can be bent, allowing you to adjust them to a fit that suits you and secure them firmly to your ears, making them less likely to fall out. Even during intense exercise like running, you don't have to worry about the running earphones bluetooth falling off. They don't hurt at all even after long hours of use. You can use them with confidence even if you sweat during exercise, as they are IPX7 waterproof. 【56 hours of playback & LED display】 The earphones themselves can play for up to 8 hours on a full charge, and when used with the charging case, you can enjoy up to 56 hours of music playback. The LED display is also designed to show the charging status of the left and right earphones, and the remaining charge of the charging case is clearly displayed in numbers from 1% to 100%. With rapid Type-C charging, it only takes about 1 hour to fully charge the case and earphones. 【Bluetooth 5.3 stable connection, automatic pairing, CVC 8.0】 Bluetooth has been upgraded from the previous older version to Bluetooth 5.2 technology, which allows for a more stable and faster connection. "Sound skipping" and "sound interruption" can be significantly improved. The transmission distance also reaches up to 10M (without obstacles). After the first use, there is automatic memory, and automatic connection is possible when the product is started from the second time, eliminating the need for complex manual pairing. Furthermore, it is equipped with CVC 8.0 noise-canceling technology.
