STAX

Founded in 1938, STAX brought the world's first electrostatic headphone to market in 1960. Today they continue their long tradition by offering the finest audio products for both professional and audiophile applications.

All STAX headphones are referred to as "earspeakers" - the company states that such ultra-high fidelity devices can only be compared with the best cost-no-object loudspeakers, not other headphones. Their unique amplifiers, earspeakers and drivers are highly sought-after products, and extremely well considered by aficionados in the audio industry.

Unilet Sound & Vision are one of the oldest STAX dealers in the UK, and one of the very few official outlets stocking their products. Do get in touch with us if you would like to audition the range, or need advice or assistance with choosing the right system for your needs.
