Planar magnetic
A headphone driver that uses a thin diaphragm with an embedded conductor sandwiched between magnet arrays. Lower distortion and faster transients than dynamic drivers; heavier and pricier.
In a planar magnetic driver, the conductor (a flat conductive trace) is bonded to a thin film diaphragm. Magnets on both sides push the whole surface uniformly — versus a dynamic driver where only the voice coil pushes the diaphragm.
Strengths
- Distortion. Sub-0.5% across the band on premium models.
- Transients. Faster than dynamics — meaningful for orchestral and electronic transients.
- Bass. Extension matches dynamics; less roll-off.
Weaknesses
- Weight. Magnets are heavy; planar headphones often exceed 400 g.
- Drive requirements. Generally low impedance + low sensitivity; benefit from a dedicated amp.
- Cost. Entry-level planars start where dynamic-driver headphones top out.
Notable: Audeze, HiFiMan, Meze (hybrid), DCA. Sennheiser's HD 800 line is dynamic; the HE 1 is electrostatic.
How to use Planar magnetic in a real comparison
A headphone driver that uses a thin diaphragm with an embedded conductor sandwiched between magnet arrays. Lower distortion and faster transients than dynamic drivers; heavier and pricier. In practice, this is most useful as one part of a decision rather than a standalone quality badge. Compare it alongside the workload, room, ecosystem, budget, and ownership constraints that apply to you; the strongest published figure is not automatically the best outcome for every buyer.
What to check next
Open a product page and check the stated value, configuration, price, and related trade-offs before treating this term as decisive. It is especially relevant in .
Avoid the one-number trap
Manufacturers can describe the same capability under different conditions. Compare like-for-like variants, check the unit and test condition where available, and use a head-to-head page to see whether a measurable difference is material for your own use.
