Infinity ES-1 Electrostatic Headphone System

This ES-1 / ME-10D was only built in limited quantities (500 pieces).

The ES-1 headphone system includes a completely new so-called low-mass membrane made of polyurethane. This follows dynamic changes much faster and more precisely than polyester or other electrostatics systems. The system consists of a headphone and an amplifier in a walnut case, in which the ME-10D adapter, power supply and matching transformers are installed.
