How Do Planar Magnetic Headphones Work?

Planar magnetic headphones are less distortion-free than dynamic drivers. This is because they vibrate the entire diaphragm, not only the part that is attached to the voice coil.

They also have a wider soundstage with better instrument separation and differentiation capabilities. They leak more, and require isolation to stop disturbing those nearby.

The diaphragm

The diaphragm plays an essential function in nearly all transducers of sound (headphones and loudspeakers, as well as microphones) that move air to create sound. In headphones it's a flat part of diaphragm, suspended between two magnets that create an electromagnetic field when stimulated by audio signals. In a planar magnetic headphone the electric current that comes from the headphone's source reaches the diaphragm through an electric coil that creates an electric force that causes it to vibrate.

The sound generated is transmitted to your ear through the diaphragm's suspended, which is often made of an artificial material, such as titanium or neodymium. The diaphragm will then resonate with your ear using different frequencies. Planar magnetic headphones are able to provide high SPLs without sounding distorted.

In addition to being able to reproduce high SPLs, planar magnetic headphones also provide a more immersive soundstage. The reason for this is because the flat diaphragm produces an asymmetrical sound wavefront instead of the spherical focused wavefront that is found in many dynamic drivers. This means that the headphones provide a more natural soundstage that's easier to localize.

The transient response is yet another benefit of headphones with planar magnets. This is the ability of headphones with planar magnetics to reproduce short-lived peaks, like cymbal smacks and kick drum hits. The huge size of the diaphragm as well as the fact that it is able to move evenly across its surface ensures that there is no distortion at these peaks.

Planar magnetic headphones have some disadvantages you should take into account when choosing a pair. One of the main reasons why they cost more is that they tend to be significantly larger than their counterparts with dynamic features. The main reason is the complexity of the drivers and the image of the brand.

There are many low-cost planar magnet headphones that are that cost less than $100. In addition to their impressive performance, these headphones are available in open-back and closed-back designs which means you can pick which one suits your listening habits best. The HIFIMAN Arya Stealth Magnets Edition and Audeze LCD-2 Classics are some of the top choices on the market.

The voice coil

Planar magnetic headphones are well-known for their accuracy and precision with incredible clarity and detail across the entire frequency range. This is due to their flat, thin diaphragm which is sandwiched between two arrays of magnets. When an electrical signal from your source of audio is sent through the conductive materials, the that wind the vocal coil react with the magnet field, and cause the dialyms to vibrate. This results in sound waves.

The planar-type driver has the advantage that every vibration occurs at the same rate and is uniform regardless of the position of the diaphragm within the magnetic field. This results in a more uniform sound quality with less distortion and an even wavefront that's easier on the ears. Dynamic drivers on the other hand, tend to produce sound waves that are less uniform and more round.

Planar magnetic drivers, due to the way they work require a more powerful amplifying system. They are also larger and heavier due to their larger, more flexible membrane. They require an external amplifier or DAC to drive them.

In addition the planar magnetic drivers are much more expensive than their dynamic counterparts because they're typically made from high-quality materials. In recent years, however some HiFi audio headphone manufacturers have revived this old technology. We're seeing a range of new headphones featuring planar magnet drivers that provide an outstanding listening experience.

Like everything else in life, the choice between planar magnetic and dynamic headphones comes down to personal preference and budget. Planar magnetic headphones have an enlargement of the soundstage than dynamic models, and are renowned for their incredible clarity and precision. Dynamic headphones are more expensive, however they offer a more powerful bass and a more rounded sound quality.

In general dynamic driver Headphones Planar generally have a little more slam and punch than planar magnetic models, but the differences are not always apparent to the majority of listeners. They also offer better imaging and separating. There are a lot of exceptions to this, and some great magnetic headphones are available at a very affordable price.

Magnets

In a typical headphones with a dynamic driver the electrical signals sent by your audio source go through a conductory material that interacts with the magnetic fields within the driver. These are then used to alter the diaphragm's flat surface and create sound waves. Planar magnetic headphones are made up of the thin layer of conductor material that is sandwiched between powerful magnets. This makes them more complicated to make and is one reason why they're usually more expensive than their dynamic counterparts.

A heavier and headphones Planar larger design is also a result of the need for more space around drivers. They also require more power to achieve their full potential than their more dynamic counterparts. This isn't a major issue often but it's something to think about when choosing these headphones.

It's not the case for all headphones but many of the best planar magnet headphones have an airier, more open sound. This gives them the impression that they are in a bigger space, which can be appealing to certain listeners. The soundstage they offer is also a bit bigger and can be useful when listening to music with other people.

A number of boutique headphone brands such as HiFiMAN and Audeze employ the open-back design. Although they're not as popular as closed-back models, they can be an excellent opportunity to experience the advantages of planar magnetic technology. The HiFiMAN Sundara, for example, is a great opportunity to feel the speed, precision and detail of these headphones.

The housing

If you're an audiophile or just someone who enjoys good music, chances are you've heard of planar magnetic headphones. They sport a unique design, with a flat diaphragm embedded in the headphone. They are available in both open-back and over-ear designs. These headphones are not only distinctive in design, but they also work with a different method than dynamic drivers.

Planar magnetic headphones, unlike traditional moving coil drivers that use a voice coil to create sound waves, use an array magnets to move the diaphragm to create sound. The arrays can be placed on either one or both sides depending on the design. The magnets are activated by an electrical signal that flows through the voice coil, causing it to vibrate. The vibrations create magnetic fields that interact with magnets on either side of the diaphragm. The interactions cause the diaphragms to pull and push against the magnetic fields. The audio signal is represented by sound waves.

Because of this, planar magnetic headphones typically sound richer and have better bass extension capabilities. The diaphragm is large and flat. responds faster to changes in the input signal, which means they are able to respond quicker to bass response and are less prone to distortion. This gives them a more precise, tight sound quality that some audiophiles like.

These headphones can reproduce higher frequencies but lack the punch and slam that modern dynamic driver headphones provide. They can be difficult to hear to for those who wish to listen to hard rock music.
