About Fearless Audio

Founded in 2012, Fearless Audio is committed to providing perfectly fit customized earphones, including in-ear monitors specialized for professional audio engineering and stage performance. As a world-class technical audio company, Fearless Audio has established a specialized digital R&D department in 2016 for the exploration and application of 3D printing technology in customized in-ear monitors. The culminating result has been the world’s first 3D-printed lowpass tuning catheter to be utilized in earphones. Today, this technology has gone beyond to developing custom tuning tubes for balanced armature and dynamic drivers in every model that allow specific tuning engineering and minimization of unit variances.

The primary focus of Fearless Audio is on users' music listening experience. Through years of cooperation with professional musicians, Fearless Audio has developed high performance earphones that suit all types of enthusiasts and musicians. During the past 9 years, Fearless Audio has been recognized as an industry leader by global consumers who insist on an unparalleled music experience.

Barcelona: Powerful and Balanced Hybrid IEM

The Barcelona is a 1 dynamic driver and 1 balanced armature driver hybrid in-ear monitor featuring Fearless Audio’s latest technological advancements. The Barcelona utilizes the new proprietary dynamic driver, the Fearless Special Research Pole-Magnetic Dynamic Driver. This powerful 10mm driver has been specially designed to focus on low frequency performance by minimizing distortion levels while enhancing membrane responsiveness through a strengthened magnetic tension. A unique compound material membrane also adds a rich texture to the low frequencies that cannot be replicated by other driver types.

The Barcelona also features a custom mid and high frequency balanced armature that was produced through collaboration between Sonion and Colorful World manufacturers. This special 2300 series driver produces extremely precise mid and high frequency details, and has been tuned for an accurate and well-balanced signature.

The Barcelona is a 2 hybrid driver IEM with a 2 way crossover. Its sound signature can be characterized as balanced, with emphasis on a powerful bass, lush and warm mids, and comfortable and natural highs.

High Performance Cable

The Barcelona comes with an 8 strand ultra-pure oxygen-free copper (OFC) silver-plated litz cable. This high-performance grade cable was selected to best enhance the sound signature of the Barcelona. With its 0.78mm 2-pin termination and 3.5mm single-ended jack, it can also be switched with other cables or in-ear monitors.
