【Keep Moving Forward, Never Be Satisfied! ▶ Ear Cuff Earphones】 For many years, Erssimo has been pursuing wireless earphones that combine new designs and high performance. The industry's first "ear cuff" design, open-ear earphones have finally arrived! These 4th generation latest Bluetooth earphones adopt a completely new open-ear audio solution developed ahead of the world. Instead of using bone conduction technology that transmits sound through vibrations, the sound emitter is positioned above the ear canal. Unlike conventional canal-type earphones that are inserted into the ear, these are worn like an ear cuff, clipped to the earlobe. This wearing style not only eliminates the vibrations of bone conduction Bluetooth earphones but also offers a different wearing experience. Furthermore, it brilliantly overcomes the shortcomings of traditional TWS earphones, realizing a new listening style. Whether in the city, outdoors, or in the office, you can enjoy music safely without blocking your ears, anytime, anywhere, and without being limited by the scene. 【Enjoy Ear Cuff High-Quality Earphones That Suppress Sound Leakage and Don't Block Your Ears!】 Equipped with a 15mm dynamic driver, these earphones clearly reproduce everything from thick bass to delicate high frequencies. Songs sound expansive, and even the melodies are clear, creating a sense of immersion, allowing you to clearly hear even the slightest whispers. As open-ear Bluetooth earphones, ear cuff earphones not only provide better sound quality compared to bone conduction Bluetooth earphones but also minimize sound leakage. By using directional sound transmission technology to deliver sound directly to the eardrum, we have succeeded in minimizing sound leakage. Whether in a quiet library or a noisy cafe, you can enjoy your favorite music and immerse yourself in your own world without worrying about those around you.
