This connection standard is commonly used in professional audio interfaces, headphone amps, and mixing consoles, making the ET-H3.0N7UB well-suited for both home and studio applications. The secure fit and durable materials ensure long-term performance across thousands of plug-in cycles.

Rhodium-Plated 2-Pin Headphone Connectors for Precise Fit
On the headphone end, the ET-H3.0N7UB uses rhodium-plated 2-pin connectors for a stable and exact connection with Fostex headphones. These connectors provide excellent durability and electrical integrity, ensuring a solid, noise-free link that won't loosen with repeated use. The rugged housing and quality plating make this cable reliable even in demanding daily use.

It's not a third-party workaround—it’s the real replacement, built to match the quality of the headphones it supports. That means no compromises in soundstage, imaging, or frequency response due to mismatched components.
