【Earaku's Unique Incus Algorithm Technology - Astonishing Audio Experience】The "Aircuff" OWS earphones employ Incus algorithm technology, which automatically adjusts the output levels of high, mid, and low frequencies based on the actual sound source and output sound pressure, optimizing the balance of the three frequency bands. This ensures a consistently comfortable and immersive listening experience. 【DSP Amplifier Function - Sound Leakage Prevention Design】The DSP amplifier optimizes sound balance, improving the balance of bass, mid-range, and treble output from the earphones, and removes noise through digital signal processing. The subtle nuances of music and the tones of instruments are conveyed more clearly, providing an immersive music experience. The adjustment of air pressure and sound cavity design in the speaker effectively suppresses sound leakage. While being open-ear, it protects the user's privacy, creates a personal space, and allows you to enjoy immersive Hi-Fi sound as it is. 【Multi-functional Touch Display - 10 Music Functions】Innovative and original design for 2025! The charging case equipped with a touch display even reduces the frequency of taking out your mobile phone. It is more compact than a mobile phone and more specialized in music functions, while reducing the power consumption issues caused by mobile phone operations. Music player, equalizer switching, all reflect Earaku wireless earphones' pursuit of sound quality and acoustic effects. Functions such as the earphone search function, timer function, and camera controller give the charging case a new role. Pursuing new functions and innovative designs is the unique experience we want to deliver to everyone! 【Lightweight Fit - IPX5 Waterproof Specification】The weight of a single earphone is only 5.8g, and the total weight is only 53g, which is about the weight and size of one egg, making it very convenient to carry when going out. The OWS earphones with IPX5 waterproof function are resistant to daily rain and sweat. This allows you to use them with confidence in humid environments, such as running and outdoor activities. In addition, simple maintenance such as wiping with a damp cloth is also possible. *After exercising and sweating a lot, wipe the sweat off the surface of the earphones before returning them to the charging case.
