4ears: Italian Excellence in Custom In-Ear Audio Monitors
4ears, an Italian brand of Munarato Srl, founded in 1993, specializes in the production of custom high-quality multi-way in-ear monitors. Based in Arre (PD), Italy, 4ears combines over twenty-five years of experience (as of 2018, now more than 30 years) in custom earphone manufacturing with ongoing research and development in the audio sector, working closely with musicians and sound engineers.
The philosophy of 4ears is to offer musicians, producers, and enthusiasts a better musical experience, with products perfectly tailored to their needs and ear shape. Each in-ear monitor is a unique piece, handcrafted in their specialized workshop.

Artisanal Craftsmanship, Multi-Way Technology, and Biocompatible Materials
The distinctiveness of 4ears in-ear monitors lies in their construction process and employed technologies:

Custom-Made: Using detailed ear impressions taken through a network of over 200 distributors throughout Italy, each earpiece is built to ensure maximum comfort, fit, and acoustic isolation (about 26dB).
Multi-Way Technology: They employ systems with dedicated drivers for specific frequency ranges (low, mid, high). The use of multiple drivers and passive crossovers or acoustic filters (Acupass Technology) ensures high-fidelity audio reproduction, detailed sound, and excellent timbre across the entire audible frequency spectrum.
Biocompatible Materials: The shells of the in-ear monitors are made with biocompatible resins certified for medical use, guaranteeing safety and hypoallergenic properties.
Premium Components: They use miniaturized, state-of-the-art drivers and components (balanced armature transducer technology) for maximum reliability and sound quality.

Models and Aesthetic Customization Options
4ears in-ear monitor models mainly differ by the number of drivers used (single, double, triple-way systems, or more). The catalog includes models such as:

SM221, DM111, SM631B.

They offer extensive aesthetic customization options, allowing customers to choose from a wide range of colors and finishes for the shells, making each in-ear monitor a unique and distinctive accessory.
