Many people are not accustomed to in-ear earbuds since they give ears a sense of pressure. FIIL has now launched an open earbud, which does not need to be put into the ear, and also provide amazing sound quality effect by hanging it on your ear. The product has been awarded the HI-RES AUDIO WIRELESS certification. Hi-Res is the gold standard for measuring high sound quality. FIIL optimized the structure of the sound cavity of the earbuds, with the human ear bionic design, the scientific distribution of different acoustic holes position and angle for directional delivery of good sound. Multiple acoustic resistance network can effectively prevent sound leakage.
