【Innovative Bone Conduction Technology】Utilizing advanced bone conduction technology, sound vibrations are transmitted directly to the inner ear through the bones near the temples, allowing you to enjoy clear sound quality without blocking the ear canal. Because sound is not transmitted through the ear canal, there is no risk of damaging the eardrum, and it provides comfortable wear even for extended periods. You can always be aware of your surroundings while both ears are open, providing peace of mind when outdoors.
【Bluetooth Functionality】Supports Bluetooth 5.3 for easy connection to smartphones and other devices. Music playback and call answering/rejecting can be done using the sound amplifier without removing the device. The sound amplifier function and Bluetooth function can be seamlessly switched by simply double-clicking the power key.
【APP Smart Operation & Custom Settings】The FIIL sound amplifier allows for volume adjustment, mode switching, and custom settings via a dedicated app. In custom mode, you can adjust the sound amplification frequency to your preference. The set frequency is automatically saved, and the next time you activate the same mode, the previous setting will be applied by default.
【4 Sound Amplification Modes & 5 Volume Levels】The sound amplifier function features four modes: "Vocal," "Indoor," "Outdoor," and "Custom." You can freely choose the setting that suits your usage scenario and surrounding environment. The volume can also be adjusted in 5 levels. It can be comfortably used in various situations such as conversations, watching TV, and listening to music.
