STAX SR-507

For more than 50 years, Stax has been dedicated to the production of premium electrostatic headphones. Based on long-term research and experience, it came in 2011 with a novelty called SR 507. This, compared to its older versions, uses a simpler structure of the speaker membrane, which is made of thin material resistant to change of shape due to temperature or humidity. The result is rich and absolutely pure sound reproduction far beyond the limits of human perception, both in low and high positions.

In addition to a perfectly precise musical interpretation, the headphones also provide a very decent portion of comfort . This is ensured especially by adjustable belt over the head and earrings made of genuine sheepskin, whose work was mainly focused on their proper breathing and sound regulation.

Electrostatic technology

Electrostatic headphones use high voltage for their operation, polarizing a thin membrane whose inertia is minimal. This is the reason why they can reproduce even the slightest realistic tone. This technology is only used for the highest quality headphones.
