CCA Polaris Earphones HIFI Bass Earbuds Monitor 4-Level Tuning Switch Headphone Sport Stereo Sound Noise Reduction Headset
Audio/IEMs
“CCA Polaris IEMs combine a hybrid driver tuning and a four‑position hardware tuning switch with a ~107dB sensitivity and switchable high impedance mode (≈50Ω) that noticeably 'opens up' the sound when engaged. Good for listeners who want on‑the‑fly tonal shaping and amp‑paired head‑fi behavior; expect average stock cable, itchy KZ-style tips, and plasticky inner finishing.”
