We are excited to present our newest offering, the Bellos Audio X3 In-Ear Monitors. The X3 is the result of years of research and development, and it delivers a sound quality that exceeds expectations. The X3 provides a natural energetic tonal coloration, especially in the lower register, thanks to the implementation of a 6mm dynamic low driver.

The X3 delivers an exemplary level of space and headroom for a triple driver IEM. With every instrument having its own space, the X3 provides a natural and dynamic sound that captures every nuance of your music. We are confident that the X3’s unique design, featuring our revolutionary In-Air Canal Technology, will set a new standard for custom in-ear monitors in the market today.

Like all X-Series, the X3 comes with a host of additional proprietary technologies such as ATOM Venting which greatly expands the soundstage, beautiful 3D Printed Matte Shells, the ultra-durable RCX Cable Connector, Modular Drivers and Removable Faceplates for quicker service and repairs.
