The planar starter guide

What planar magnetic means in practice

An ordinary headphone driver is a cone pushed from one point by a voice coil. A planar magnetic driver is a thin film with the conductor traced across its whole surface, suspended between magnets and driven evenly everywhere at once. Three things follow. Notes start and stop faster, so drums, plucked strings and dense mixes come through less smeared. Bass arrives as texture rather than one warm thump — you hear the kick and the bass line as separate events. And distortion stays low as volume rises, so busy passages hold together instead of blurring.

The trade-offs are physical too. Magnet arrays make planars heavier than most dynamic headphones. Nearly all of them are open-backed. And although their impedance is low, their sensitivity usually is too — they want current, which phone and laptop jacks were never built to deliver in quantity.

Open versus closed, without the romance

Open backs are a large part of why planars sound spacious: the film breathes in both directions. The cost is that sound travels both ways too. The room hears your music, thinly, and you hear the dishwasher. A planar is a headphone for a desk or a sofa in a room you control.

Said plainly: if your listening happens on the bus, in an open office or next to a sleeping partner, do not buy an open planar and hope. A closed dynamic like the Beyerdynamic DT 770 PRO will serve that life better — the 32 Ω version if it has to run from a phone. The Sundara Closed-Back exists for exactly this problem and is a good headphone, but closing the back softens some of the openness you came for — treat it as the compromise it is, not a loophole.

Power, honestly

Planar impedance numbers look reassuring — most HiFiMans sit well under 50 Ω — but sensitivity is modest, and that is what decides real-world volume. From a laptop or a phone dongle, the HE400se, Sundara, Edition XS and Ananda Stealth all play at sensible desk levels. What you give up without an amp is headroom: the top of the volume range arrives strained, and bass loses some of the grip that is the point of the technology.

A small desktop unit fixes it. The EF499 is the sensible first amp — enough current for everything up to the Ananda, with a proper DAC built in. The EF500 adds power and is the better buy if you already know you are climbing. The Arya Organic is where "runs from a laptop" stops being usefully true: it will make noise from one, but it only sounds like an Arya on a desktop amp — EF500 at minimum, EF600 comfortably. The EF600 also drives everything else on our shelf, Susvara included, which makes it the last amp purchase rather than the first.

The ladder, with honest stopping points

• HiFiMan HE400se — the cheapest way to find out whether the planar presentation suits you. Fed from a laptop at a desk, it already does the speed-and-texture trick. If you were curious rather than committed, stop here and feel no shame.
• HiFiMan Sundara — the step that changes the most per euro on this page: cleaner treble, firmer bass, a metal build that takes years of daily use. This is our default recommendation, and most people should stop here.
• HiFiMan Edition XS — a wider, deeper picture and more bass reach than the Sundara. The catch is fit: the cups are large, the clamp is light, and smaller heads never feel quite held. Try one on before committing if you can.
• HiFiMan Ananda Stealth — the refinement step: smoother treble and an easier fit for long sessions. Worth it if you listen for hours at a stretch; skippable if you do not.
• HiFiMan Arya Organic — the top of the sensible ladder. More of everything the XS hinted at, with enough resolution that recordings start sounding different from each other rather than just better. It assumes a desktop amp from day one. Beyond it sit the HE1000 V4 and the Susvara — real gains, but they assume matching electronics and a quiet, dedicated room. They are not starter purchases, and the Arya is the correct place for this guide to end.

One maintenance note

Planar pads compress with use, and the tuning shifts with them. Dekoni's HE-series pads fit the HE400se and Sundara; the Arya and Ananda series have their own set. A pad refresh every couple of years keeps the headphone you bought sounding like the headphone you bought.
