Audio Technica ATH-CK9

The Audio Technica ATH-CK9 in an in-ear headphone equipped with balanced armature drivers that deliver high-fidelity audio. An affordable downgrade from the ATH-CK10, the ATH-CK9 supports a lower impedance (30 ohms versus 55 ohms) and sensitivity (104 dB versus 107 dB).

The ATH-CK9, however, maintains the ATH-CK10’s 3 mW maximum input power. The ATH-CK9 also features an acoustic seal for improved sound isolation, a hard protective case, interchangeable S/M/L earpieces, and a reversible design that allows the earphones to be worn with the cord extending either above or below the ear. The Audio Technica ATH-CK9 is available in either black or white, and is priced at $179.95, a whopping $170 savings from the $349.95 ATH-CK10.
