Stax was formed in 1938 in Japan and in 1960 they released their first electrostatic Headphone or ‘Earspeaker’ as they are better known. Being an electrostatic design, a Stax Earspeaker requires an energiser unit to drive them making it a complete package. Over the last 50+ years Stax have refined their designs making them the leaders in electrostatic headphones and arguably the leaders in high performance headphones today.
The first SR-Lambda series was introduced 36 years ago and it has further developed into a new-generation SR-Lambda with its newly designed enclosure – the new SR-L700 advanced-Lambda series Earspeaker.
