This provides a consistently comfortable and immersive listening experience. 【DSP Amplifier Function & Sound Leakage Prevention Design】 The DSP amplifier optimizes the sound balance, improving the balance of low, mid, and high frequencies in the earphone output, and removes noise from the earphones through digital signal processing.
