Get to know them!

Fourté benefits from everything 64 Audio has learned about crafting world-class in-ear monitors. These IEMs boast an extremely accurate sound, along with a wide, expansive soundstage. You'll enjoy resonance- and distortion-free listening, thanks to Fourté's complete 3-part Tia system, while Apex technology ensures effortless audio reproduction and minimal wearing fatigue. These universal-fit IEMs offer detailed, lifelike sound, with incredible dimensionality. Listening to Fourté is an addictive experience, making these earphones a great choice for discerning audiophiles. Fourté boasts an eye-grabbing look as well, with ergonomic shells machined from solid aluminum and elegant copper patina faceplates.

Distortion-free sound and long-wearing comfort

Fourté delivers a first-class listening experience. Its complete 3-part 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, Fourté's Apex technology 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.

64 Audio Fourté 4-driver Universal In-ear Monitors Features:

  • Universal-fit in-ear monitors with audiophile-quality sound
  • Complete 3-part Tia system supplies resonance- and distortion-free listening
  • Apex technology ensures effortless audio reproduction and minimal wearing fatigue

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.

If you do not, interest will be charged on the promo balance from the purchase date. The required minimum monthly payments may or may not pay off the promo balance before the end of the promo period, depending on purchase amount, promo length and payment allocation.

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.
