The Stax SR-X MK2 is an electrostatic headphone model manufactured by Stax, a company recognized for its electrostatic audio technology. The SR-X MK2 is characterized by its lightweight design and detailed sound reproduction, making it a compelling choice for audiophiles. It employs electrostatic transducer technology, which helps achieve a very low distortion level and an extended frequency response, resulting in clear, dynamic audio playback across a wide spectrum of music genres. The headphones feature a circumaural design, providing a comfortable fit that aids in sound isolation. They require a dedicated electrostatic headphone amplifier to operate effectively, as they operate on a different principle compared to traditional dynamic headphones. The build quality incorporates high-grade materials, ensuring durability and a premium feel. Specifications typically include an impedance of around 145 kΩ, a frequency response range from approximately 10 Hz to 30 kHz, and a weight of around 240 grams, making them suitable for long listening sessions without fatigue. The SR-X MK2 is also known for its ability to convey an open, airy soundstage, which enhances the listening experience, particularly for classical and acoustic music.
