4ears - in-ear headphones

The story of 4Ears began in 1993 within Munarato Srl, a workshop specialized in custom earphone manufacturing. Based in Arre (PD), 4ears is today one of the Italian references for the production of custom multi-driver in-ear monitors for musicians and sound professionals.

With over thirty years of experience, the company combines artisanal craftsmanship with technological research, developing custom earphones with optimal acoustic isolation, premium components, and high-fidelity sound. Each piece is unique, built from the customer’s ear molds to ensure absolute comfort and professional performance.

Construction Philosophy, Techniques, and Materials

4ears construction techniques

The philosophy of 4Ears is summed up in three words: anatomical adaptation, premium sound, and safety. Each earphone is created from the impression of the ear canal for a perfect fit and about 26 dB of noise isolation.

Main features:

  • Artisanal construction: each piece is hand-finished in the workshop.
  • Multi-way technology: dedicated drivers for low, mid, and high frequencies for maximum fidelity.
  • Biocompatible materials: medically certified resins and safe components.
  • Premium components: Balanced Armature transducers and proprietary acoustic filters.

The integration of artisanal know-how and 3D printing techniques guarantees precision and consistent performance.
