EARS PRO is a professional headphone test fixture for accurate, repeatable acoustic measurement in R&D and manufacturing applications. Based on the extensive feedback from the original EARS platform, we went back to the drawing board to design a no compromise, all in one testing jig. It pairs a sturdy, adjustable fixture and human‑like soft silicone pinna with IEC 60318‑4 couplers, unique per‑unit calibration files, and a precision 1/2" prepolarized measurement capsule for low‑noise, traceable frequency response.

The integrated USB Audio 2x2 (UAC2) interface with XMOS processing and ASIO drivers delivers low‑latency connectivity to Windows, macOS and Linux. Onboard electronics include low‑noise mic preamps, adjustable analog gain, an internal headphone amplifier and a stereo DAC. Together, they form a complete system for your testing application.

Engineered for headphone R&D, production QA and calibrated binaural recording, EARS PRO’s quick‑change adapters, precise positioning and robust build enable high‑throughput testing without sacrificing laboratory accuracy, providing manufacturers and labs a compact, traceable solution for objective and subjective evaluation.



WARNING: The USB 2x2 interface used in EARS PRO is a very specific interface for ICP microphones requiring low noise, high gain and correct phantom power supply (24V). A simple USB microphone preamp for audio recording isn't an acceptable replacement (E.g. RME/Motu..etc) as they could damage the microphone and void warranty. Please contact our support team first if you are planning for an alternative microphone interface so we can help guide your selection.
