Driver unit for Earspeakers

Features

The SR-003 is a 5-pin PRO bias type in-the-ear earspeaker, and can be used by connecting to a driver unit having 5-pin PRO bias output socket. Also, the inner type structure of the SR-003 enables you to enjoy excellent electrostatic sound readily without covering your ears. The SR-003 connects to STAX driver units or adapters equipped with 5-pin type PRO bias output.
