Fidue Acoustics has released their latest multi-BA high-resolution in-ear monitors, the all-new Fidue Gem 4. For all those who don’t know about Fidue, they are a well-reputed brand based out of China that focuses primarily on high-resolution in-ear monitors and their cables. They have a team of highly experienced audio engineers, who are the backbone of their research and manufacturing team. Their latest Gem 4 features a four-driver composite balanced armature driver unit on each side that is tuned to deliver a natural, transparent sound that complements different genres of music well. The drivers are arranged in a self-designed acoustic cavity without any damping or ducting using precise three-way electronic crossover for distortion-free sound production. The earpieces in Gem 4 are designed with medical-grade resin material using high-precision 3D printing technology. Fidue Gem 4 is released worldwide at a price tag of 479.99$.

Quad-Driver High-Resolution Balanced Armature Configuration:-

Fidue Gem 4 features a quad-driver high-resolution BA configuration per side consisting of four custom-tuned BA drivers. The drivers are tuned to produce high-resolution crisp sound output with strong bass, accurate midrange, and sweet treble, a transparent sound according to the Fidue acoustic engineers.

Accurate Three-Way Frequency Division:-

Fidue has years of experience in multi-unit IEM tuning and designing. The Gem 4 has received a mature multi-channel electronic frequency division circuit. The energy of this circuit is finely adjusted to make each driver unit perform with its full potential. This effectively reduces distortion or overlapping of frequencies in the circuit as each driver is tuned specifically to respond to a particular portion of the frequency response range.

No Damping No Ducting, An Independent Acoustic Cavity:-

Fidue uses a specially designed independent acoustic cavity structure without any damping or ducting. This no damping not only reduces unnecessary harmonics caused by ducts and dampening tools, in fact, it also contributes to the natural, transparent sound tuning of the pair. The sound cavity modules are completely separated from the ground effectively reducing crosstalk between each driver unit. Gem 4 also features an independent air diversion AG module specially designed for Balanced Armature drivers. They provided an air vent for the powerful woofer like with DD units. It greatly improves the sound quality with strong power, clarity, and resolution.

3D-Printed Ear Cavities Made Using Medical-Grade Resin:-

In order to reduce any acoustic flaws caused by the difference in the accuracy of shell production, Fidue has opted for a high-precision 3D printing process to craft the Gem 4 earphones. They are made using skin-friendly medical-grade resin material that also helps in making the pair light-weight and comfortable. The pair has an ergonomic design which allows the users to have a comfortable & firm fit making the pair suitable for long listening sessions.

High-Purity Silver-Plated Single Crystal Copper Cable:-

Fidue Gem 4 is bundled with a high-purity silver-plated monocrystalline copper cable that has very low internal resistance to the sound signal and at the same time, it greatly improves the channel separation degree. It has standard 2-pin connectors and a 3.5mm termination plug for easy connectivity.
