Unique Appearance Design

Oh2S in-ear earphones adopt a unique mixed material appearance design and use a special resin material to achieve efficient sound damping.

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 tonal balanced, the in-ear headphones use resin and aviation-grade aluminum alloy as the sound cavity to achieve the physical frequency division effect.

It can minimize the mutual interference between the sound unit generator and make the sound more pure and transparent.

1BA+1DD configuration

iKKO in-ear monitors adopt unique separating vector acoustics system technology, the precisely designed cavity structure makes the sound volume, reflection, diffusion angles, and the unit performance display to the greatest extent in a limited space.

Excellent treble performance

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

Oh2S 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.
