Enquire about this product

In excellent secondhand condition the Stax SR-L700 is an electrostatic ear speaker (commonly referred to as a headphone) from the renowned Japanese brand, Stax. Stax is well-known for their electrostatic technology and the high-quality audio reproduction that their ear speakers deliver. Here’s an overview of the SR-L700 and its features:

Pricing available on application which will includes installation and shipping costs to your nominated location
  1. Electrostatic Design: Unlike conventional dynamic or planar magnetic headphones, electrostatic headphones use a thin diaphragm placed between two stator plates. When music is played, an electrical charge is applied to the diaphragm, causing it to move and produce sound. This design typically results in very fast transient response, high resolution, and a lack of distortion.
  2. Sound Quality: The SR-L700 is often praised for its detailed and transparent sound signature. The highs are crisp, mids are clear, and bass is tight and precise, though it may not have the weight that some dynamic headphones provide.
  3. Comfort: The SR-L700 features large, rectangular ear cups that are designed to go around the ears. They are relatively lightweight, which contributes to comfort during long listening sessions.
  4. Design and Build: The SR-L700 features a high-quality build with metal and high-grade plastic components. The earpads are made from a combination of leather and other materials for comfort.
  5. Special Amplifier Requirement: Electrostatic headphones require a dedicated electrostatic amplifier to operate, due to the unique way they produce sound. This means you can’t just plug them into any standard headphone jack. Stax produces a range of amplifiers to pair with their ear speakers.
  6. Price Point: Stax ear speakers, including the SR-L700, are premium products with price tags to match. They are an investment but are often considered worth it by audiophiles for the unique listening experience they offer.

If you’re considering purchasing the SR-L700 or any other Stax product, it’s essential to audition them first, if possible, to see if the sound signature and feel match your preferences. Remember, sound is subjective, and what sounds amazing to one person might not be to another.
