High-driver-count IEMs with Unparalleled Sound

Get to know them!

Nio is 64 Audio’s first high-driver-count hybrid, offering a universal-fit earphone with a 9mm dynamic driver and eight balanced-armature drivers — that’s nine drivers altogether. You’ll enjoy resonance- and distortion-free listening, thanks to Nio’s Tia system, while an Apex Core ensures effortless audio reproduction and minimal wearing fatigue. What’s more, LID technology ensures consistent sound regardless of what playback device you plug your earphones into. These IEMs yield unparalleled sound, with extended lows and a rich, three-dimensional soundstage, along with smooth highs and a natural warmth that will have you listening for hours. They boast an eye-grabbing look as well, with an ergonomic shell machined from a solid piece of aluminum and an elegant abalone faceplate.

Distortion-free sound and long-wearing comfort

Nio delivers a first-class listening experience. Its Tia System minimizes unwanted resonances and distortion, delivering a transparent, life-like sound. Its 9mm Dynamic Driver and 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, Nio’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.

Consistent performance with any playback device

Armed with LID Technology, Nio accounts for the nonlinear impedances of the multiple driver-sets comprising its 9-driver design. This ensures proper interaction regardless of what you plug into. Whether you’re listening from a smartphone, bodypack, or headphone amplifier, your source material will sound the same.

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.
