IKKO OH10 In-Ear Headphones

Pure copper cavity hybrid structure

The cavity of OH10 is made of pure copper combined with the hybrid acoustic design to reduce the internal harmonic resonance. A titanium coating is used on the outside of the cavity to prevent scratching. It also inhibits bacterial growth. The cavity inside is coated with platinum. The overall design lowers the distortion and delivers more delicate and natural sound. 

Dual titanium driver

The hybrid design consists of one Knowles 33518 balanced armature driver supplying treble with good extension and one 10mm polymer titanium diaphragm dynamic driver delivering low end with nice transient response.

2-pin 0.78mm detachable design and high purity OFC silver-plated cable

OH10 comes with a high-purity OFC silver-plated cable. It has a 2-pin 0.78mm detachable design and can be replaced if the cable is damaged accidentally. The cable provides nice treble airiness and bass authority.
