The Best Bone Conduction Headphones for Beginners】 Unlike conventional earphones that transmit sound through the eardrum, Erssimo's bone conduction earphones use the latest proprietary 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 you won't get tired even after long hours 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! Compatible with glasses. If you're a beginner or don't like in-ear earphones, Erssimo's bone conduction earphones are perfect! 【Perfect for Sports! The Best Running Partner】 Erssimo's bone conduction earphones use a titanium frame, which provides a soft yet secure hold, so they won't fall off even if 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 - 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 like the music has become a part of you! 【Type-C Fast Charging & 8-Hour Battery Life】 Compared to conventional magnetic charging, the newly released HS1 bone conduction earphones use a USB Type-C charging port, solving the problem of the magnetic part getting hot during charging. They also support fast charging, making charging 'safe', 'fast', and easy and convenient, providing up to 1.2 hours of use with a 10-minute quick charge.
