Fully wireless earphones that pursue clarity, bass, and silence. 【Extra ANC: Up to -49 dB of Silence】2 microphones x feedforward + feedback control accurately cancels environmental noise. External sound input (ambient) can also be switched with the side button. 【FUNLOGY Pure Sound Engine】The 10 mm composite diaphragm driver combines the flexibility of PU with the high rigidity of Ti alloy. It reproduces clear high frequencies, thick mid-low frequencies, and tight deep bass in a balanced manner, making live sound sources and game sound effects clear and powerful. 【3D Fit Sound Tuning】By pursuing a fit and directivity that matches the human ear, and through unique tuning that applies head-related transfer functions, you can experience immersive sound as if there were speakers right in front of you in movies, 360° audio, and VR content. 【Unison Fit Ergonomics】Analyzing ear shape data from hundreds of people, we have achieved a balance between ANC performance and wearing comfort. It is comfortable to wear for long periods of time and won't slip even when jogging. 【Beamforming + ENC Calls】A total of 4 microphones (left and right) collect sound in a forward direction. Even when using ANC simultaneously, only your voice is delivered clearly, instantly solving the problem of "difficulty hearing" in online meetings and game voice chat. 【60 Hours of Playback & Wireless Charging】Up to 10 hours of continuous playback with the main unit alone / up to 60 hours with the case. Fully charged in about 1 hour via USB-C port, and wireless charging is also supported.
