64 Audio’s Top-of-the-line IEMs

Get to know them!

U18t is 64 Audio’s top-of-the-line, reference-class in-ear monitors. You’ll enjoy resonance- and distortion-free listening thanks to U18t’s Tia system, while an Apex Core ensures effortless audio reproduction and minimal wearing fatigue. These universal-fit IEMs boast an industry-first design that pushes the limits of what a reference monitor can be. U18t offers unparalleled detail and unmatched clarity across all frequencies, along with muscular lows and incredible sub-bass extension. Tailor-made for mission-critical applications, these earphones are ideal for engineering, monitoring, mixing, and audiophile listening. They boast an eye-grabbing look as well, with an ergonomic shell machined from a solid piece of aluminum and an elegant copper-patinated faceplate.

Distortion-free sound and long-wearing comfort

U18t delivers a first-class listening experience. Its Tia System minimizes unwanted resonances and distortion, delivering a transparent, lifelike sound. Its open-balanced armature Tia Drivers radiate freely into a single large Tia bore, resulting in zero obstructions to the front of the drivers. We’re impressed by this design here at Sweetwater; it offers a significant step up when compared to lesser designs that constrict the sound of their drivers by cramming them into a tube. What’s more, U18t’s Apex Core employs a patented vent that releases air pressure in a sealed ear canal, all while maintaining isolation. This ensures less obstructed airflow, giving you ultra-clean audio along with long-wearing comfort.

Offer applies only to single-receipt qualifying purchases. Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
