Dynamic vs Planar vs Electrostatic Headphone Drivers

What the driver word on a listing means

The driver is the part of a headphone that turns an electrical signal into sound. Listings often name the driver type in the title or in the bullet list: dynamic, planar, or electrostatic. Each word describes a different way of building that part, so the first step in reading a listing is knowing which word you are looking at and what it names.

The driver word is a construction name, not a quality claim. Comparing two pairs on the driver word alone does not tell you which one suits a commute, a desk, or a recording room. This site compares listings on stated details: fit, connection, closed-back or open-back, battery figures when a title prints one, and the words a listing names.

Titles may also print driver size, for example 40 mm. The size is another construction detail, explained in the driver size and type guide. The same listing may name the driver type, the driver size, and the earcup back, and each word is read separately.

Dynamic drivers: the common listing word

A dynamic driver uses a voice coil, a magnet, and a diaphragm. Current passes through the coil, the coil sits in the magnet's field, and the movement of the coil moves the diaphragm. The diaphragm pushes air, and that movement is the sound you hear.

Dynamic is the most common driver word on headphone listings. Apple's AirPods Max page describes an Apple-designed dynamic driver, and soundcore's page names 40 mm dynamic drivers on its over-ear headphones. beyerdynamic's site names Tesla headphones, including the T1 and T5 models made at its Heilbronn site. Most wireless headphones, earbuds, studio pairs, and DJ pairs use dynamic drivers.

When a listing says dynamic, the word tells you the construction. What it does not tell you is whether the pair cancels noise, how long the battery lasts, or whether the cable is detachable. Read those details from the title and the maker's page. For wireless pairs with a dynamic driver, see the best wireless headphones guide.

Planar magnetic drivers: a flat diaphragm

A planar magnetic driver, also called planar or isodynamic, uses a flat diaphragm with a conductor trace. The diaphragm sits between two magnets, and current in the conductor moves the whole surface. Because the entire diaphragm moves as one piece, the construction is different from a dynamic driver's coil-and-diaphragm design.

HIFIMAN names planar headphones on its site, including the HE1000 WiFi Media Planar Headphone. Fostex's RP series, such as the T50RP and T60RP, are planar stereo headphones. A title that prints "planar magnetic" tells the reader the construction before the bullet list.

Planar pairs are often over-ear and often open-back or semi-open, and many are wired. The earcup back is a separate detail from the driver type. For the difference between the two words, read the dynamic vs planar magnetic drivers guide and the closed vs open-back guide.

Electrostatic drivers: a charged film

An electrostatic driver uses a very thin, charged film as the diaphragm. The film hangs between two perforated plates, and an electric field moves it. This is a different construction from dynamic and planar types.

Electrostatic headphones need a special amplifier with a bias supply. A phone, a laptop, or a Bluetooth connection cannot drive them. The maker's page will state what amplifier the pair is designed for, and that statement is part of the listing word set you compare. If the page names no amplifier, the listing leaves a needed detail unstated.

Electrostatic listings are rare on headphone marketplaces. When a title says electrostatic, read the maker's page for the amplifier requirement and the included parts before you buy. The headphone DAC and amp needs guide explains what to look for in a desktop setup.

Power and your listening setup

Dynamic headphones connect to the widest range of sources in general terms: a phone, a laptop, a headphone amp, or a mixing desk. For a commute, a train, or a flight, a wireless dynamic pair with noise cancelling is a common match. See the best noise cancelling headphones guide.

Planar magnetic headphones are often wired and may be paired with a headphone amplifier. Read the maker's page for the stated amplifier needs, since some planar listings state they work with a phone or laptop and others name an amplifier as a companion. For a home desk, the best over-ear headphones guide compares wired over-ear pairs.

Electrostatic pairs sit outside the common marketplace range because of the amplifier requirement. If a listing says electrostatic, treat the amplifier as part of the purchase decision. For wired listening, the best wired headphones guide is a starting point.

How to compare listings with different driver words

A driver word alone does not decide a purchase. Compare pairs on stated details: over-ear or on-ear, wireless or wired, closed-back or open-back, battery figures when a title prints one, and the Hi-Res or codec words a title names.

If two listings differ only in the driver word, read both maker's pages. The page may state the driver size, the magnet type, the amplifier needs, and whether the cable is detachable. These are the details the site compares. When one page states a detail the other leaves out, the unstated detail is a reason to read the listing carefully.

For a recording desk, a closed-back dynamic pair is a common choice on studio listings; see the best closed-back headphones guide. For a wired pair with Hi-Res words on the title, see the best Hi-Res headphones guide. For an open-back pair in a quiet room, see the best open-back headphones guide.

What to pick for your situation

Questions

What is a dynamic driver in a headphone?

A dynamic driver uses a voice coil, a magnet, and a diaphragm. Current in the coil moves it inside the magnet's field, and the coil moves the diaphragm to create sound. Dynamic is the most common driver word on headphone listings, and most wireless, earbuds, studio, and DJ pairs use dynamic drivers.

What is a planar magnetic driver?

A planar magnetic driver uses a flat diaphragm with a conductor trace between two magnets. The whole diaphragm moves when current flows through the conductor. HIFIMAN and Fostex name planar headphones in their product lines, often on wired over-ear listings.

What is an electrostatic driver?

An electrostatic driver uses a thin charged film as the diaphragm, placed between two plates. An electric field moves the film. Electrostatic headphones need a special amplifier with a bias supply and appear on few marketplace listings.

Do electrostatic headphones need a special amplifier?

Yes. Electrostatic headphones need an amplifier with a bias supply. A regular headphone jack or a Bluetooth connection cannot drive them. Read the maker's page for the stated amplifier requirement before buying.

Which driver type is most common on listings?

Dynamic. Most wireless headphones, earbuds, studio pairs, and DJ pairs use dynamic drivers. Planar magnetic pairs appear on wired over-ear listings, and electrostatic pairs are uncommon on marketplaces.

Does the driver word on a title tell me how a pair compares?

No. The driver word names the construction method, not a comparison. This site compares stated details only: fit, connection, earcup back, battery figures, and codec words. The driver word is one of those details, read as a name.

Can I use planar headphones without a headphone amplifier?

Read the maker's page for the stated amplifier needs. Some planar listings state they work with a phone or laptop; others name a headphone amplifier as a companion. The page states what the pair is designed for.
