64 AUDIO / Nio Universal Fit IEM 64A-8434

64 AUDIO Nio is a hybrid earphone with nine drivers, consisting of a 9mm diameter dynamic driver and eight balanced armature (BA) drivers. It delivers an unparalleled three-dimensional soundstage.

The modern mother-of-pearl inlay design on the faceplate shines beautifully like a jewel.
Nio's robust aluminum housing is ergonomically designed to fit many people's ears as a universal model. The faceplate is inlaid with a mother-of-pearl inlay that shines as beautifully as a jewel and is captivating for its sound and appearance.

Tia Technology, a revolutionary new technology that overturns conventional earphone design, dramatically improves sound quality.
Tubeless In-ear Audio (tia) technology is a new technology that revolutionizes earphone design by using a sound conduit in a conventional balanced armature (BA) type driver to produce sound through a sound conduit and a sound hole. the technology eliminates the use of conduits in BA-type drivers. Instead, it uses a unique tubeless design that allows the true sound from the driver to be delivered directly to your ear. By eliminating a sound conduit, sound resonance problems inside the conduit and sound attenuation problems caused by a filter (damper) are eliminated, which can degrade sound quality.

New "apex" technology reduces air pressure on the eardrums, reduces fatigue caused by prolonged listening, and helps protect hearing.
When earphones block the ear canal, the speakers produce air pressure (sound pressure). This air pressure can cause ear fatigue or even risk hearing loss due to excessive pressure on the eardrum. apex technology (Air Pressure Exchange Technology) was developed to reduce the risk of such hearing loss. By having a specially designed "apex module" in the earphone housing, the air pressure that would normally be continually applied to the eardrum is released through the apex module, thereby reducing the burden on the eardrum. This reduces auditory fatigue caused by prolonged listening, making maintaining hearing for longer periods easier. The reduced stress on the eardrums relieves tension and improves auditory sound quality.

Single-bore design to take advantage of the ■tia driver
The single-bore design is a new earphone design that uses a single large-diameter sound conductor hole as the sound exit. The single bore design enables a "tubeless design" that eliminates sound resonance caused by the sound conduit, allowing the "tia driver" to maximize its potential. The large-diameter sound conduit is an acoustic chamber and a key element in sound tuning, enabling more accurate tuning.

Linear Impedance Design" developed for various listening environments
LID (Linear Impedance Design) was developed to ensure that the sound balance of the IEMs (in-ear monitors) is not affected when connected to various player devices with different output impedance, such as high-resolution digital audio players (DAPs), smartphones, and portable amplifiers. This new design is designed to ensure that the sound balance on the IEM (in-ear monitor) side is not affected when connected to various player devices with different output impedance, such as high-resolution digital audio players (DAP), smartphones, and portable amplifiers.
