How Do Planar Magnetic Headphones Work?
Compared to dynamic drivers, planar magnetic headphones have lower distortion. This is due to the fact that the whole diaphragm is vibrating rather than only the portion that is connected to the voice coil.
They also have a larger soundstage, which is better separated and differentiation capabilities. They leak more, and require isolation to prevent the sound from affecting those who are around you.
The diaphragm
The diaphragm plays a crucial function in nearly all sound transducers (headphones and loudspeakers, as well as microphones) that move air to create sound. In headphones the diaphragm is suspended between two magnets, and generates an electromagnetic field when activated by audio signals. In a planar magnetic headphone, the electric current emanating from the headphone's source is transferred to the diaphragm via an electric coil that creates a magnetic force that causes it to vibrate.
The sound generated is transferred to your ear via the diaphragm's suspension, which is usually made of an artificial material such as titanium or neodymium. The diaphragm can then resonate with your ear using different frequencies. Planar magnetic headphones are able to provide high SPLs without sounding distortion-free.
In addition to the ability to reproduce high SPLs, planar magnetic headphones also provide a more immersive soundstage. The reason for this is that the flat diaphragm produces a planar sound wavefront, rather than the narrow spherical wavefront found in most dynamic drivers. This means that the headphones deliver an enveloping soundstage that is more easily to locate.
Another advantage of planar magnetic headphones is their excellent transient response. This is due to their ability to recreate short-lived peaks in audio signals, such as the cymbal crash and kick drum strikes. The diaphragm has a large diameter and is evenly distributed across the surface, so there's no distortion when peaks are reached.
However, the planar magnetic headphones do have some drawbacks that should be considered when selecting the best set. They are usually much more expensive than their dynamic counterparts. The main reason for this is the complexity of the driver and the reputation of the brand.
There are many affordable planar magnet headphones that cost less than $100. These headphones are available in open-back and close-back designs. You can choose the one that best fits your listening preferences. The HIFIMAN Arya Stealth Magnets Edition and Audeze LCD-2 Classics are some of the top options available.
The voice coil
Planar magnetic headphones are well-known for their accuracy and precision with amazing clarity and detail across the entire frequency range. This is due to the thin, flat diaphragm sandwiched between magnet arrays. When an electrical signal is sent through your audio source, the material that conducts it's windings inside the voice coil interact with the magnetic field, causing the diaphragm's surface to vibrate, producing sound waves.
The planar-type driver benefits from the fact that each vibration happens at the same rate and is consistent, no matter the position of the diaphragm within the magnetic field. This produces an even and consistent sound with less distortion. It is also easier to listen to. Contrary to this, dynamic drivers tend to produce an elongated sound wavefront that's less consistent and can be distracting.
Due to the way in which they operate due to their design, planar magnetic drivers require a more powerful amplifier system than their dynamic counterparts. They are also heavier and bulkier because of their larger and more flexible membrane. In turn, they usually require an external amplifier and DAC to provide sufficient power to drive them.
Additionally that, magnetic drivers that planar are more expensive than their dynamic counterparts since they're usually made of high-end materials. Nevertheless, a few specialized HiFi audio headphone companies have started to revive this technology in recent years. We're seeing a wide range of new headphones with planar magnet drivers that provide an excellent listening experience.
As with all things in life, the choice between planar magnetic and dynamic headphones is based on your personal preferences and budget. Planar magnetic headphones offer an enlargement of the sound stage than dynamic models and are renowned for their incredible detail and accuracy. Dynamic headphones are more expensive but they have a heftier bass and a more rounded sound signature.
In general dynamic driver headphones offer a bit more punch and slam than the planar magnetic ones, but the differences aren't always noticeable to most listeners. They're also better at imaging the structure and differentiation. There are some exceptions to the rule. Some excellent planar-magnetic headsets can be bought at affordable prices.
best magnetic planar headphones
In a headphone that has a dynamic driver, electrical impulses generated by your audio source travels through a coil of conductive material that interacts with magnetic fields inside the driver. They are then used to manipulate the diaphragm's flat shape and generate sound waves. Planar magnetic headphones on the other hand are made up of a thin sheet of conductive material that's sandwiched between two powerful magnets. They are more difficult to manufacture, which is why they're more expensive.
They also tend to be bigger and heavier because of their design which requires more space around the drivers. They also require more power to reach their full potential than their dynamic counterparts. This isn't a major issue often but it's something to think about when choosing these headphones.
Although this isn't the case for all headphones, many of the top headphones with a planar design will provide an open and airy sound than their dynamic counterparts. They also provide an airy feel that can be quite appealing for some listeners. They also offer a larger soundstage, which can be helpful when listening to music with others.
The open-back design is a favorite choice for many small-scale headphone brands, such as the likes of HiFiMAN and Audeze. Although they're not as popular as closed-back models, they're an excellent opportunity to experience the benefits of planar magnetic technology. The HiFiMAN Sundara, for example, is a great way to test the speed, accuracy and clarity of these headphones.
The housing
If you're an audiophile or just a person who enjoys good music, it's likely you've heard of the planar magnetic headphones. They have a distinctive appearance, featuring a flat diaphragm embedded in the headphone. They are available in over-ear and open-back designs. In addition to the unique design, these headphones also employ different working principles as in comparison to dynamic drivers.
Planar magnetic headphones, in contrast to traditional moving coil drivers, which use the voice coil to produce sound waves, employ array of magnets to move the diaphragm to produce sound. Based on the design, these arrays can be situated on both sides of the diaphragm. The magnets are activated when an electrical signal passes through the voice coil, causing it to vibrate. The vibrations generate magnetic fields that interact with the magnets at either side of the diaphragm. The magnetic fields cause the diaphragms push and pull. The audio signal is represented using sound waves.
Planar magnetic headphones are able to produce a richer sound and better bass extension. The diaphragm is large and flat. responds more quickly to changes in input signals, so they respond quicker to bass response, and are less prone to distortion. This creates a cleaner and more controlled sound that many audiophiles love.
Although these headphones may be able to reproduce higher frequencies, they do not have the punch or slam that is found in modern high-end dynamic driver headphones. They can be difficult to listen for those who want to listen to hard rock music.
Planar magnetic headphones are costly because of their unique design. The drivers are powered by an audio digital converter and a specialized amplifier. Some people may feel that the price of these headphones is more expensive, but they believe that it's worth it. There are other kinds of headphones that are available to those who do not need to spend a lot.
