iBasso IT01x Audiophile IEMs (B-Stock Factory Refurbished)

iBasso Audio IT01x Audiophile In-Ear Monitor

Double-sided Beryllium-plated Diaphragm Brass Internal Cavity | 3D Suspension High Magnetic Flux | Helmholtz Resonator MMCX Connector

High-Density Brass Internal Cavity

Unlike many other IEMS with an iron internal cavity, the IT01X uses brass for the inner dynamic driver cavity. The higher density of brass can effectively reduce resonance and reduce distortion. This special internal cavity provides a deep and powerful low frequency along with an engaging mid frequency.

Dual Helmholtz Resonators

The unique brass dual Helmholtz resonators provides a deep and powerful bass that cancel standing waves and ensures full natural sound.

Double-sided Beryllium-plated Diaphragm

We tried countless times using metal plated diaphragms of magnesium, titanium, and beryllium plating with different suspensions and with many different tuning materials. Finally, we chose plating each side of the driver with beryllium for the IT01X. The density of beryllium is only 1/2 of that of titanium. The lighter weight diaphragm allows. the IT01X to be driven with ease. The double-sided beryllium-plated diaphragm has outstanding rigidity, quick response with extremely low distortion, smaller internal resistance, wider high frequency bandwidth, and better overall treble extension.

3D Suspension

The IT01X utilizes a 3D (three-dimensional) suspension. It can effectively inhibit the divided vibration of the driver, reduce the distortion, and further improve the sound purity.

High Magnetic Flux NdFeB Magnet

IT01X utilizes a high magnetic flux neodymium-iron-boron (NdFeB) magnet, which drives the thin and light double-sided, beryllium-plated diaphragm efficiently, giving the IT01X excellent dynamics and transient response.

Detachable MMCX Cable

An MMCX detachable high purity copper cable with a silver-plated shield, is a high quality standard. The 3.5mm gold-plated plug housing and the cable splitter are made of stainless steel.

Mastery of Tuning

iBasso has been deeply involved in the HiFi field for 15 years and has a rich experience in tuning from Audio players, Amps to headphones and IEM. On IT01X, not only the new technologies such as double-sided beryllium-plated diaphragms and brass internal cavities are used, but also iBasso's unique insight into sound aesthetics is brought together.

A Truly Comfortable Fit

Our ergonomically designed shell adds to long term comfort, allowing you to relax and enjoy the music.

Metallic Painted Shell

The shell of the IT01X is finished with a metallic paint that is popular on luxury cars. This metallic paint adds hardness to the shell with an appearance that has a smooth beautiful luster.
