64 Audio U18t Earphone
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. 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. 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.
A revolutionary technology that eliminates pneumatic pressure that causes excessive eardrum movement.
tia HIGH DRIVER
The tia high driver is located in the tia single bore (canal stem). Because of the extremely short sound path of the high driver, we’ve achieved a remarkable high-frequency extension and smoothness.
By removing pneumatic pressure from the ear canal, sound is felt to be more spacious and outside the head when compared to traditional earphones.
Sound bores are used to channel the sound from a driver or a group of drivers to the eardrum. Multi-bore designs allow unique frequency shaping capabilities.
