【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 latest 4th generation 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 speakers are positioned above the ear canal. Unlike typical 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 while protecting your ears anytime, anywhere, without being limited by the scene. 【Enjoy Ear Cuffs: High-Quality Earphones That Don't Block Your Ears and Minimize Sound Leakage!】 Equipped with a 15mm dynamic driver, these earphones clearly reproduce everything from deep bass to delicate high frequencies. Songs sound expansive, and even the melodies are clear, creating a sense of immersion. You can even hear subtle breaths clearly. 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. Directional sound transmission technology successfully delivers sound directly to the eardrum, minimizing sound leakage. Whether in a quiet library or a bustling cafe, you can immerse yourself in your own world while enjoying your favorite music without worrying about those around you.
