Stax SR-L300 Electrostatic Headphone

$ 430.00

The Most Famous Electrostatic Headphone in the World…The Legendary Stax SR-L300.  

The first time you hear an electrostatic headphone, you’re immediately stunned by the transparent sound quality that easily outperforms dynamic and planar magnetic competitors.  The moving diaphragm is ultra low mass, making it ultra fast, for the best transient response ever. This is a true Open Air design, no back-wave interference with the natural di-pole output, just like full range electrostatic speakers.

Recordings you thought you knew become 3 dimensional, the way sound is heard in real life. The ear cups are large and rectangular because inside there’s an oval full range electrostatic speaker.  Soft Alcantara Leather ear cups provide a soft, luxurious fit with plenty of room for large ears.  They look different because they are different from every other headphone, a classic in its own time.

The SR-L300 is the entry-level full range Stax electrostatic headphone at a price never thought possible.
