5. What is the OAK NANO's tuning style?

  The OAK NANO adopts a beryllium metal diaphragm featuring high rigidity, extremely low density, and high sound velocity. Therefore, breakup distortion during high-speed vibration is effectively suppressed, resulting in silky smooth, soft, and fatigue-free treble. The midrange has slight coloration, giving vocals a rich and warm quality rarely found in metal-diaphragm earphones. With a warm sound signature, well-positioned vocals, and high density, it is perfect for pop and vocals. The bass delivers strong dynamics, with fast and precise drum beats, excellent control, and clean, low-noise floor. It avoids excessive reverberation that might otherwise create an overwhelming sense of bass pressure.
