KZ S1 TWS - Truly Wireless Earbuds
KZ has gained experience with TWS earphones. After releasing the KZ E10, KZ T1, here come the KZ S1D / S1 TWS earphones. Both models use AAC's unique encoding technology to achieve faster transmission, better sound quality and smaller files during transmission. Although the size is small, but the energy is large, a fuller midrange and bass frequency is released than expected.
