IO (Eye-Oh) presents an all new fun and engaging listening experience. IO’s sound is fast and resolving. It’s refined mid range complements extended high frequencies and articulate bass. The result is fidelity unmatched by any other in-ear monitor in its class.
Many more iterations and unique prototypes were made of IO than any other earphone in Campfire Audio’s line up to date. It was a journey to fine tune the sound and get it right. The result is an earphone that can proudly stand next Campfire Audio's best-known models.
