64 AUDIO / 64A8434

64 AUDIO Nio is a 9-driver hybrid earphone consisting of a 9mm dynamic driver and eight balanced armature drivers (BA drivers), delivering an unparalleled three-dimensional sound stage.

■Modern mother-of-pearl design on faceplate that shines beautifully like a jewel
・The robust aluminum housing used in Nio is ergonomically designed and designed to fit the ears of many people as a universal model. The faceplate is finished with mother-of-pearl that shines beautifully like a jewel, and is captivating not only for its sound but also for its appearance.

■Dramatically improves sound quality with the revolutionary new technology ""tia technology"" that overturns conventional earphone design
・tia (Tubeless In-ear Audio) technology is a new technology that revolutionizes earphone design itself by using a sound guide tube in the balanced armature driver (BA type driver), which is the conventional earphone design, and outputting sound from the sound guide hole through the sound guide tube. tia technology does not use a sound guide tube for the BA type driver, but instead adopts a unique tubeless design, allowing the original sound emitted from the driver to be delivered directly to your ears. By not using a sound guide tube, it is possible to eliminate factors that deteriorate sound quality, such as sound resonance problems that occur inside the sound guide tube and sound attenuation problems caused by using a filter (damper).

■Apex is a new technology that not only reduces the air pressure on the eardrum and reduces fatigue caused by long-term listening, but also helps protect your hearing.

When earphones block the ear canal, the earphone speaker generates air pressure (sound pressure). This air pressure can cause ear fatigue and even put excessive strain on the eardrum, which can lead to hearing loss. Apex technology (Air Pressure Exchange Technology) is a technology developed to reduce the risk of hearing loss. By installing a specially designed ""apex module"" in the housing of the earphones, the air pressure that would normally be applied to the eardrum is released through the apex module, reducing the strain on the eardrum. This reduces hearing fatigue caused by long-term listening, makes it easier to maintain your hearing for longer, and reduces stress on the eardrum, relieving tension and improving the sound quality.

■Single bore design that makes the most of the tia driver

The single bore design is a new earphone design that uses a single large-diameter sound guide hole as the sound outlet. The single bore design enables a tubeless design that eliminates sound resonance caused by the sound guide tube, maximizing the potential of the tia driver. This large-diameter sound guide hole itself acts as an acoustic chamber, and also functions as the key to sound tuning, allowing for more accurate tuning.

■ Linear impedance design developed to accommodate various listening environments

- LID (Linear Impedance Design) is a new design designed to ensure that the sound balance of the IEM (in-ear monitor) is not affected even when connected to various player devices with different output impedances, such as high-resolution digital audio players (DAPs), smartphones, and portable amplifiers.
