64 Audio Nio
Design & Construction
First high driver-count hybrid UIEM featuring a 9mm dynamic driver and 8 balanced armature drivers. The drivers and other patented components are housed in an ergonomic shell machined out of solid aluminum. Finished with a naturally sourced striking blue abalone faceplate making each pair truly unique.
Sound Signature
Sound signature characterized by extended lows and a rich 3-dimensional soundstage. Smooth treble and natural warmth will provide hours of enjoyable listening for all genres of music. With the included variety of tips and apex modules you can take Nio from a saturated tube-like warmth all the way to a neutral reference monitor tonality.
Tubeless In-Ear Audio (tia)
Tubeless In-Ear Audio (tia) is a patented IEM design methodology that aims to reduce unwanted resonance and distortion for a transparent and lifelike sound signature. The tia system is comprised of three major elements: open balanced armature tia drivers, the tia single-bore design, and tia acoustic chambers. Nio features two major elements of the tia system: the tia driver and the tia single-bore design.
Air Pressure Exchange (Apex)
Air Pressure Exchange (Apex) is a patented vent that releases air pressure in a sealed ear canal all while retaining standard IEM levels of isolation; enabling musicians and music enthusiasts to listen more comfortably for longer. This venting alleviates listener fatigue and allows for a much more realistic soundstage. Apex comes in three module variations for Nio: mX, m15 and m20.
Linear Impedance Design (LID)
Linear Impedance Design (LID) is a patented circuit that corrects the non-linear electrical resistance of the multiple driver-sets comprising this 9 driver IEM. Varying source amplifier output impedance in devices like smartphones, body packs, DAC/amps, and DAPs typically results in varying frequency response across them, depending on the increase in resistance. Restoring proper interaction with the source and preserving the desired sound signature enables a consistent reliable sound.

Value for Money
85/100
Built around a nine-driver, four-way design, the 64 Audio Nio pairs ambitious engineering with interchangeable Apex isolation options. Available evidence is limited on sound, but Audiophilepure found the included foam tips stayed securely attached during use. Its premium specification and configurable isolation make it an intriguing in-ear monitor for listeners who favor the supplied tips.
What Reviewers Are Saying
Pros
Included foam tips held securely to the nozzle during the reviewer's use.
&
Cons
The nozzle lacks a retaining lip, so some third-party silicone tips may remain in the ear canal when removing the IEMs.
The review sample showed a paint chip on one shell, raising a finish-quality concern for that unit.
SOUND QUALITY PERFORMANCE 50/100
The supplied review excerpts do not discuss the Nio's tuning, detail retrieval, staging, or dynamic performance. No reliable listening consensus can be drawn from the available material.
Bass
50/100
The available review excerpts contain no comments on sub-bass extension, impact, control, texture, or bass-to-midrange balance. Bass performance is therefore not established by the provided evidence.
Midrange
50/100
Reviewers provide no observations about vocal placement, timbre, instrument body, or upper-midrange presence. The supplied material is silent on midrange performance.
Treble
50/100
There is no reviewer commentary on treble extension, air, smoothness, sibilance, or fatigue. The available evidence does not support a specific treble assessment.
Resolution Separation
50/100
The excerpts do not address microdetail, layering, instrument separation, or performance in dense recordings. Reviewers offer no direct evidence on resolving ability.
Soundstage Imaging
50/100
No comments are provided on soundstage size, depth, image placement, or spatial precision. The supplied review material does not assess imaging.
Dynamics Coherence
50/100
The review excerpts do not discuss transient response, punch, rhythmic drive, or integration between drivers. There is no direct evidence about dynamic behavior or coherence.
FIT COMFORT ISOLATION PERFORMANCE 57/100
Fit can be dependable with the supplied foam tips, which the reviewer found held securely on the nozzle. However, third-party silicone tips could remain in the ear during removal, and the excerpts do not address long-term comfort or real-world isolation.
Seal Stability
67/100
Audiophilepure reports that some third-party silicone tips could be left in the ear canal when removing the Nio, creating a practical fit concern. The supplied foam tips held tightly to the nozzle and were the reviewer's preferred solution.
Comfort
50/100
The supplied excerpts do not describe shell pressure, nozzle comfort, insertion depth, or fatigue during extended listening. Comfort is not meaningfully assessed in the available review evidence.
Isolation
50/100
Although the product offers interchangeable Apex isolation modules, the supplied review excerpts do not report actual passive isolation performance. No reviewer evidence establishes how effectively it attenuates outside noise.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Accessories
63/100
Audiophilepure identifies two finish and usability concerns: a nozzle without a retaining lip and a paint chip on the review sample's shell. The included foam tips appear more secure than third-party silicone alternatives, but the excerpts provide little broader information about cable quality, case, connectors, or long-term durability.
Value for Money
85/100
At roughly $1,649-$1,699, the Nio sits in a premium IEM segment. The supplied review excerpts do not directly assess whether its performance, construction, or accessories justify that asking price against competing models.
