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, with sound reaching the brain as vibrations through the bones! The first-ever bone conduction earphones feel 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 use! Furthermore, we have succeeded in reducing sound leakage by about 50% compared to conventional bone conduction earphones. They also work well 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】 These 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. They are compatible with the waterproof and dustproof standard 【IP55】, so they are also resistant to rain and sweat! You can easily control "music playback/pause, skip forward, skip back, volume up, volume down, answer/hang up/end calls" with one hand. 【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! 【Type-C Fast Charging & 8 Hours of 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. The HS1 bone conduction earphones are slim and lightweight, yet have a long battery life. Continuous playback time is up to 8 hours. * Shipping method may be changed from Rakuraku Mercari to Yu-Yu Mercari. * Will be shipped using the cheapest method, including regular mail. ☆Instant purchase is welcome☆ Please check the profile before purchasing♪ #Hiyokotachi'sShop 2795/286.520 $$2780
