The world's first lithium-magnesium diaphragm IEM
IKKO's OH5 earphones feature the world's first lithium-magnesium diaphragm, creating an opera-like broad sound field experience. This material is usually found in high-end home audio systems and offers superb resolution and extension. IKKO is the first brand in the world to integrate this lithium-magnesium diaphragm into in-ear headphones (IEM/In-Ear Monitors). After a year of repeated adjustments, the OH5 is finalized with a 12mm single dynamic driver, encased in a titanium alloy and resin chamber for full and powerful echoes. The masterpiece of sound tuned by iKKO is similar to a sound on the cloud. It delivers a full and rich sound with deep and vibrant low frequency. Additionally, there’s no crossover network, giving you a natural and wide soundstage that resembles classic premium HiFi speakers. OH5 uses 4 strands of 24-core all-single-crystal copper silver-plated wire. Single-crystal copper can enhance sound separation silver plating can add brightness to high frequencies, thereby greatly reducing sound distortion and enabling music to restore every beat. In addition, OH5 has three interchangeable plugs of 2.5mm, 3.5mm, and 4.4mm, making it compatible with various source devices.
