Unique Design - Combination of Resin and Metal

When designing OH1S, IKKO designers made a bold innovation combining metal and resin, reducing the overall weight of the earphone. Resin and aviation aluminium alloy are used as the sound cavity of the moving coil and moving iron to achieve the effect of physical frequency division, minimize the interference between the units, make the sound more pure and transparent.

The sound outlet of the earphone is oval, which fits the ear canal better and is comfortable and natural.

Unexpected sound balance

32Ω10mm Deposited Carbon Nano Dynamic Coil + Knowles 33518 unit hybrid driver makes the three frequency balanced, the in-ear headphones use resin and aviation-grade aluminium alloy as the sound cavity to achieve the physical frequency division effect.

It can minimize the mutual interference between the sound generating units and make the sound more pure and transparent.

1BA+1DD Moving coil + moving iron configuration

IKKO in-ear monitor adopts unique separating vector acoustics system technology, the precisely designed cavity structure makes the sound volume, reflection and diffusion angles, and the unit performance is displayed to the greatest extent in a limited space.

Excellent treble performance

Clear highs, thick mids, steady bass, every frequency band has unexpected performance.

OH1S improves the high-frequency resolution, enhances the penetration of treble and the resolution of super high-pitched, and highly restores the resolution of the full frequency range.

Lightweight to wear

The combination of resin and metal reduces the weight of the IEM. The net weight of a single IEM is only 5g.

Through the improvement of product materials, the wearing comfort is greatly improved, and sometimes you may even forget that you have been wearing the IEM for a long time.

127um high purity OFC silver plated wire

OH1S upgrade cable is composed of 127um high-purity single crystal copper silver-plated magnetic core, the upgrade cable provides high-fidelity sound data transmission, double-strand braided wire and fully wrapped design, effectively solving the problem of cable winding and reducing the weight of the cable.
