The U6t boasts the same groundbreaking technology as their flagship IEMs. While looking towards U12t for sonic inspiration, the U18s influenced the new dark grey matte aluminum shell finish. In standard 64 Audio fashion, U6t is a balanced natural sounding earphone, slightly set apart from our other UIEM models by offering a softer presentation of a mix. Beautiful upper-mid imaging, realistically presenting instruments as well as breathing life into saturated mid-bass mixes.
