Cayin YD01 Fantasy IEM Earphone

Cayin Fantasy has got a low impedance rating of just 37 ohms with high sensitivity rating of 108dB. It can be powered easily using smartphones but using a Hi-res player is recommended for best performance.

Traditionally dynamic drivers have a single cavity design usually on the front. Cayin has specially designed a large 10.3mm dynamic driver unit with a dual-cavity design. There's a cavity on the front and another on the back of the dynamic driver unit. These dual-cavities have better air pressure management as compared to single-cavity drivers resulting in the swift movement of the diaphragm coil. This results in an overall smoother, low-distortion output for its users.
