Audiophile headphones planar

Planar magnetic headphones deliver high-fidelity sound with ultra-low distortion, using thin film diaphragms suspended between magnets.

About this subject

Planar magnetic headphones are a transducer technology distinct from traditional dynamic drivers. Instead of a voice coil and paper cone, they use a thin, flexible diaphragm (usually Mylar or PET) with a printed conductive circuit, suspended between two arrays of neodymium magnets. When electrical current flows through the circuit, the diaphragm moves uniformly and precisely, generating sound waves with extremely low harmonic distortion.

The principle was patented in the 1970s by companies like Yamaha (though their NS-10s were studio monitors, planar headphones gained traction in the 2000s). Today, brands like Audeze, Hifiman, Fostex, and Oppo produce iconic models such as the Audeze LCD-4 and Hifiman Susvara. These headphones are renowned for fast transient response, deep bass extension, and wide soundstage, making them favorites among audio engineers and audiophiles.

A technical curiosity: planars typically have low impedance (20, 30 ohms) but low sensitivity (85, 95 dB/mW), requiring powerful amplifiers to drive properly. Weight is another factor, models like the LCD-4 exceed 600 grams, demanding good ergonomic comfort. Despite high cost (many above $5,000), they are considered reference-grade for sound reproduction, with flat response and minimal coloration.

Frequently Asked Questions

What makes planar headphones different from dynamic ones?

Planar headphones use a thin diaphragm between magnets, while dynamics use a coil and cone. Planares offer lower distortion, faster response, and better linearity, but are heavier and more expensive.

Do I need a special amplifier for planar headphones?

Yes, most planars have low sensitivity and require dedicated headphone amplifiers or powerful DAPs to reach proper volume without distortion.

Which brands are planar headphone references?

Audeze, Hifiman, Fostex, MrSpeakers (Dan Clark Audio), and Oppo are leading brands. Models like Audeze LCD-4, Hifiman HE1000, and Dan Clark Stealth are top-tier.
