With an impedance of 6.2 Ohms, these IEMs are highly sensitive and easy to drive. While they will work with standard mobile devices, they are designed to reveal the high-resolution output of premium digital audio players or dedicated DACs.
The Radial Venting Acoustic Chamber is designed to optimize the airflow of the dual dynamic drivers. This results in a more natural, expansive bass response that feels punchy and resonant without overpowering the rest of the frequency spectrum.
Yes, the PathFinder features an ergonomic housing design crafted from aluminum and stainless steel. While the build is durable and premium, the shape is contoured to sit securely and comfortably in the ear for extended periods.
The package includes a high-quality silver-plated copper litz cable. It comes with interchangeable terminations for 2.5mm, 3.5mm, and 4.4mm jacks, ensuring compatibility with a wide range of audio sources.
