The Kojo Keyagu is an unique high-end earphone combining solid Japanese technology with Kojo’s expertise in brass. With its stunning contrast of shiny brass and subdued yellow, it lights up any music environment. With its detailed, dynamic and natural sound signature, you will never want to stop the music.

The included high-quality re-cable is made using PC-Triple C conductor to maximise signal transmission by reducing graining. The cable includes a single wire with high conductivity at the centre and an ultra-fine wire at the outer circumference to transmit high frequency signals. It also has a conductor structure that takes into account the epidermal effect in cable signal transmission.
The sheath is made of fluorine resin and the conductor and sheath intervention yarn is made of silk thread to ensure high resistance to noise and static electricity, high stability and fast transmission speed, soft and supple texture and ease of use.
In addition, the 4.4φ plug and mmcx connector are gold-plated to improve sound quality and prevent oxidation, and the branch brackets are engraved with the logo “Keyagu”(friend in Tsugaru).
