The 64 Audio U18 Tzar™ is the world’s first universal-fit earphone with 18 balanced armature drivers per ear. It is the pinnacle of in-ear sound, designed for the most discerning listeners, audiophiles, and musicians who are searching for the ultimate reference sound. Pairing up a massive collection of 8 low drivers and 8 mid drivers with the tia™ high and high-mid drivers, all in a shell that's actually smaller than our previous universal-fit flagship 12 driver model!
The result is an incredibly tight low end, super transparent mids, remarkable high-frequency extension, and an out-of-this-world depth and soundstage. The U18 is designed with a combination of tia drivers and conventional drivers. Sound from the low and mid drivers combines in the tia single-bore and blends with amazingly detailed highs from the proprietary open balanced armature tia high driver.
A protective mesh covering at the end of the stem helps to keep out debris while apex™ module technology allows for customizing the sound signature and reduces air pressure inside the ear canal for fatigue-free listening.
All of this technology is housed in an aluminum shell for unmatched durability and beauty with elegant copper inlay patina faceplates. We pushed the limits with innovation and design to pack this kind of punch in a super ergonomic universal-fit design and are thrilled to finally drop this bomb on the in-ear monitor industry.
