Bone Conduction Earphones】 Unlike conventional earphones that transmit sound through the eardrum, Erssimo's bone conduction earphones use the latest unique bone conduction technology, where sound reaches the brain as vibrations through the bones! The first-time wearing experience of these bone conduction earphones is as light as a feather, weighing only 29g!! You can hear music without blocking your ears, so there's no feeling of pressure, and they're comfortable even for long periods of use! Furthermore, we have succeeded in reducing sound leakage by approximately 50% compared to conventional bone conduction earphones. In the city, outdoors, or in the office, you can enjoy music safely in any situation while protecting your ears! They also work well with glasses. Bone conduction earphones are perfect for beginners or those who don't like in-ear earphones! 【Perfect for sports! The best running partner】 Erssimo's bone conduction earphones use a titanium frame, which provides a soft yet secure hold and won't fall off even when you shake your head from side to side or strain yourself. The neckband is also soft and flexible while maintaining its holding power, providing a secure fit even during intense training such as weight training! 【Truly wireless, bone conduction earphones bluetooth, and enjoy music more freely!】 Bluetooth 5.0 communication provides a stable Bluetooth connection that won't be affected by congested radio wave environments outdoors! Because they are completely wireless, you'll be free from the hassle of cables, and you'll feel as if the music has become a part of you! 【Type-C fast charging & 8-hour battery life】 Compared to conventional magnetic charging, the newly released portable earphones bone conduction HS1 uses a USB Type-C charging port, solving the problem of the magnetic part getting hot during charging.
