How Do Planar Magnetic Headphones Work? Planar magnetic headphones are less dispersed than dynamic drivers. This is because the whole diaphragm is vibrating rather than only the portion connected to the voice coil. They also have a wider soundstage, with better separation of instruments and distinction capabilities. However, they do leak a bit more, which means you need to isolate yourself to ensure that no one disturbs people near 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 it's a flat piece of diaphragm, suspended between two magnets which create an electromagnetic field when activated by audio signals. In planar magnetic headphones, the electric current emanating from the headphone's source is transferred to the diaphragm through an electric coil that creates magnetic force, which causes it to vibrate. The diaphragm suspension is made of neodymium, titanium or other synthetic materials. The diaphragm is then able to resonate with your ear using various frequencies. Unlike dynamic drivers, planar magnetic headphones can provide very high SPLs without sounding muffled or distorted. Planar magnetic headphones aren't only capable of reproducing high SPLs but also have a superior soundstage. This is because the flat diaphragm generates a planar wavefront instead of the spherical focused wavefront found in many dynamic drivers. The headphones produce an overall soundstage that is more natural that is easier to localize. Another advantage of the planar magnetic headphones is their exceptional transient response. This is due to the ability of planar magnetic headphones to reproduce peaks that last only a few seconds, like cymbal smacks and kick drum strikes. The large diaphragm's size and the fact that it's able to move in a uniform manner across its surface mean that there's no distortion in these peaks. Planar magnetic headphones come with a few disadvantages you should take into account when selecting a set. They generally cost more than their dynamic counterparts. This is mostly due to the design of their drivers, which can be quite complex, and also the history of the brand behind them. There are a variety of affordable planar magnet headphones that cost less than $100. These headphones are available in both open-back and close-back designs. You can choose the one that is most suitable for your preferences in music. The HIFIMAN Arya Stealth Magnets Edition and Audeze LCD-2 Classics are some of the top options on the market. The voice coil Planar magnetic headphones offer exceptional clarity and precision across all frequencies. This is largely due to their flat, thin diaphragm which is sandwiched between two arrays of magnets. When an electrical signal is sent by your audio source the material that conducts it's windings inside the voice coil react with the magnetic field and cause the diaphragm's surface to vibrate creating sound waves. headphone planar -type driver has the advantage that each vibration occurs at the same rate and is consistent, no matter the location of the diaphragm in the magnetic field. This produces a more consistent and uniform sound with less distortion. It is also easier for the ear. Contrary to this, dynamic drivers tend to create more of a spherical soundwavefront that's less uniform and can be distracting. Planar magnetic drivers due to the way they operate requires a stronger amplifier system. They are also heavier and bulkier due to the larger, more flexible membrane. They require an external amplifier or DAC in order to drive them. Planar magnetic drivers are more expensive due to the fact that they are typically constructed of top-quality materials. However, a handful of specialized HiFi audio headphone companies have begun to revive this older technology in recent years. Consequently, we're experiencing a variety of stunning new headphones that feature planar magnetic drivers, which provide an exceptional listening experience. As with all things in life, the decision between planar magnetic and dynamic headphones is based on the individual's preferences and budget. Planar magnetic headphones offer a somewhat larger sound stage than dynamic models and are renowned for their incredible clarity and precision. However, they're often more expensive, and a lot of listeners prefer the powerful bass and warm sound of dynamic headphones. In general, dynamic driver headphones have some more punch and slam than the planar magnetic ones however, the differences are not often apparent to most listeners. They also offer better imaging and distinction. There are exceptions to the general rule. The best planar-magnetic headsets can be purchased at very affordable cost. Magnets In a typical headphone that has a dynamic driver, the electrical impulses sent by your audio source travel through a coil of conductory material which interacts with the magnetic fields inside the driver. These are then used to alter the diaphragm's flat surface and create sound waves. Planar magnetic headphones however are made up of a thin sheet of conductive material, which is sandwiched between two powerful magnets. This makes them a bit more complex to produce, which is one of the reasons they're usually more expensive than their dynamic counterparts. They are also heavier and bigger due to their design which means they require more space around the drivers. They also require more power to achieve their full potential than their dynamic counterparts. Although this isn't always a problem, it's something to be aware of when thinking about these headphones. It's not true for all headphones, but the top planar magnet headphones have a more open, airy sound. This creates an airy feel that can be very appealing to some listeners. They also provide a wider soundstage, which is useful when listening to music together with others. The open-back design is a common option for a number of boutique headphone brands, including the likes of HiFiMAN and Audeze. While they're not as common 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 way to test the speed, accuracy and detail of these headphones. The housing If you're an audiophile, or just someone who enjoys good music, it's likely you've heard of magnetic headphones that planar. They have a distinctive look with a flat-embedded diaphragm that can be found in both open-back and over-ear headphones. These headphones are not just distinctive in design, but they also operate with a different method than dynamic drivers. In contrast to the traditional moving coil driver that relies on a voice coil to generate sound waves the planar magnetic headphones utilize magnets that move the diaphragm back and forth in order to generate sound. Based on the design, these arrays can be placed on one or both sides of the diaphragm. The magnets are activated by an electrical signal that passes through the voice coil, causing it to vibrate. The vibrations generate magnetic fields that interact with magnets on either side of the diaphragm. The interactions cause the diaphragms pull and push against the magnetic fields. The audio signal is represented using sound waves. Planar magnetic headphones can provide a more resonant sound and a more extended bass. The diaphragm is large and flat. responds much faster to changes in the input signal, so they are able to respond quicker to bass response and are less prone to distortion. This results in a more precise, more regulated sound that many audiophiles love. Although these headphones might be capable of reproducing higher frequencies, they don't have the punch or slam that is found in modern high-end dynamic driver headphones. They aren't the best choice to for those who wish to listen to hard rock music. Planar magnetic headphones are costly due to their unique design. The drivers are powered by an audio digital converter and a separate amplifier. This can add up to an expensive cost increase for some buyers, however many people think the sound is worth the cost. There are many other types of headphones available for those who don't want to spend too much.
