How Do Planar Magnetic Headphones Work?

Planar magnetic headphones are less distorted than dynamic drivers. This is due to the fact that the whole diaphragm vibrates rather than just the portion that is connected to the voice coil.

They also have a more spacious soundstage with better instrument separation and ability to differentiate. They do leak more and require isolation to prevent disturbing those around you.

The diaphragm

The diaphragm plays a crucial part in almost all transducers of sound (headphones and loudspeakers, as well as microphones) that move air to produce sound. In headphones the diaphragm is suspended between two magnets and creates an electromagnetic field upon activation by audio signals. In planar magnetic headphone, the electric current generated by the source of the headphone is transferred to the diaphragm by a coil. This coil generates a magnetic field that causes the diaphragm to vibrate.

The diaphragm suspension is composed of titanium, neodymium or other artificial materials. This allows the diaphragm to resonate with your ear at various frequencies. Planar magnetic headphones are able to provide high SPLs, but without sounding distortion-free.

In addition to the ability to reproduce high SPLs, planar magnetic headphones also offer a superior soundstage. This is due to the flat diaphragm creates the planar wavefront rather than the spherical focused wavefront found in many dynamic drivers. This means that the headphones deliver an enveloping soundstage that is easier to localize.

Transient response is a further benefit of planar magnet headphones. This is due to the ability of headphones with planar magnetics to reproduce short-lived peaks such as cymbal hits and kick drum hits. The diaphragm has a large diameter and moves evenly across the surface, ensuring there is no distortion when peaks are reached.

However, planar magnetic headphones have a few drawbacks which should be considered when choosing the right set. One of the main reasons why they cost more is that they tend to be significantly larger than their dynamic counterparts. The main reason for this is the complexity of the drivers and the image of the brand.

There are fortunately excellent, affordable planar magnetic headphones that you can purchase for under $100. These headphones are available in both open-back and close-back designs. You can choose the one that best fits your personal preferences for listening. The HIFIMAN Arya Stealth Magnets Edition and How Do Planar Magnetic Headphones Work Audeze LCD-2 Classics are some of the top options available.

The voice coil

Planar magnetic headphones are known for their precision and accuracy providing exceptional detail and clarity across the entire frequency range. This is largely due to their flat, thin diaphragm, which is sandwiched between two arrays of magnets. When an electrical signal from your source of audio is transmitted, the conductive materials windings in the vocal coil react with the magnetic field and cause the dialyms to vibrate. This produces sound waves.

The benefit of a planar-type driver is that every vibration is evenly distributed and at the same rate, regardless of the location where the diaphragm is situated within the magnetic field. This results in a more consistent and uniform sound with less distortion. It is also easier to listen to. Dynamic drivers on the other hand, tend to produce sound waves that are less uniform and more round.

Planar magnetic drivers because of the way they operate require a more powerful amplifying system. They are also heavier and bulkier because they require a larger, more flexible diaphragm. They require an external amplifier or DAC in order to drive them.

Planar magnetic drivers can be more expensive due to the fact that they are typically made from high-quality components. In recent years, however a few HiFi audio headphone makers have revived this old technology. We're now seeing a variety of new headphones that have planar magnet drivers that provide the best listening experience.

Like everything else in life, the decision between dynamic and planar magnetic headphones is based on your personal preferences and budget. Planar magnetic headphones have an enlargement of the soundstage than dynamic models and are known for their exceptional quality and precision. Dynamic headphones are more expensive but they offer a more powerful bass and a warmer sound quality.

The headphones with a dynamic driver tend to have more punch and slam, but this difference is not often noticed by listeners. They are also better at capturing structure and distinguishing. There are exceptions to the rule. A variety of excellent planar-magnetic headphones can be bought at affordable costs.

Magnets

In a headphone with dynamic driver, electrical impulses from the source of your audio are transmitted through a coil made of conductive material which interacts with magnetic fields within the driver. These impulses are then used to alter the diaphragm's flat shape and generate sound waves. Planar magnetic headphones are made up of an extremely thin layer of conductors sandwiched between powerful magnets. This makes them a bit more complex to produce and is one reason why they're often more expensive than their dynamic counterparts.

They also tend to be heavier and bigger due to their design, which requires more space around the drivers. They also require more power to achieve their full potential than their more dynamic counterparts. Although this isn't always a problem, it's something to be aware of when thinking about these headphones.

While this may not be the case for all headphones, a lot of the top planar magnetic headphones will offer an open and airy sound than their dynamic counterparts. This can give them a sense that they are in a larger space, which can be appealing to certain listeners. The soundstage they provide is also larger which can be beneficial when listening to music with other people.

A number of boutique headphone brands such as HiFiMAN and Audeze make use of the open-back design. Although they're not as popular as closed-back models, they can be an excellent way to experience the strengths of planar magnetic technology. The HiFiMAN Sundara, for example is a great opportunity to test the speed, accuracy and clarity of these headphones.

The housing

If you're an audiophile or just someone who enjoys music, odds are you've heard of planar magnetic headphones. They have a distinct appearance with a flat-embedded diaphragm, which can be found in both over-ear and open-back headphone designs. These headphones are not only distinctive in design, but they also work on a different principle than dynamic drivers.

Contrary to the traditional driver that uses a voice coil to generate sound waves the planar magnetic headphones utilize an array of magnets that move the diaphragm back and forth in order to generate sound. These arrays can be placed on either or both sides depending on the design. The magnets are activated by an electrical signal that passes through the voice coil and causes it to vibrate. The vibrations generate 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 using sound waves.

Because of this, headphones made of planar magnetics typically sound richer and offer greater bass extension capabilities. The diaphragm is large and flat. responds much faster to changes in input signals, which means they respond more quickly to bass response and are less susceptible to distortion. This creates a cleaner, more regulated sound that many audiophiles love.

These headphones can reproduce higher frequencies, but they lack the slam and How Do Planar Magnetic Headphones Work punch modern dynamic driver headphones provide. Therefore, they may be a bit difficult to listen to for those who want to to listen to metal or hard rock music.

Due to their distinctive design they are more expensive than other types of headphone. The drivers are powered by an audio converter digital and a dedicated amplifier. This can result in a significant cost increase for some consumers, but many believe that the sound is worth it. There are a variety of headphones available for those who do not want to spend too much.
