The Pioneer SE-700 are vintage headphones first introduced in 1974, notable for their unique piezo-electric drivers. This type of driver, rarely seen in other headphone models, results in an airy and crisp sound profile, often compared to electrostatic headphones. The bass response is minimal, aligning with the characteristics of piezo-electric technology. The headphones feature an elegant metal frame and gimbals, designed for comfort and usability, although their fit differs slightly from contemporary models. The lightweight design incorporates leather cushions and an adjustable headband for improved ergonomics. The wiring connections for the drivers are delicate and require careful handling to avoid damage. Pricing for these headphones typically ranges from $80 to $150, with many users opting to replace aging components such as the wiring, headband, and ear pads to restore their functionality and comfort.
