HIFIMAN SUNDARA Over-Ear Full-Size Planar Magnetic Audiophile HiFi Headphones

The Sundara by HiFiMAN is an open-back, over-ear headphone. The headphone’s overall design is fantastic, and it’s a major step up from the HiFiMAN HE 400S and 400i. The HiFiMAN Sundara is made of good materials; the majority of this headphone’s materials are steel, with a few plastic elements. Let’s start with the headpiece. It has a steel band on top and a head suspension made of protein leather. Steel bands connect the headband to the earcups. The yokes attached to the earcups allow for a swinging motion up and down.

The earcups are angled, and a breathable mesh material on top gives them a nice feel, despite their lack of thickness. The housing of the earcups is constructed of metal and is circular. The outside of the earcups has a metal mesh that improves the headphone’s visual appearance. The HiFiMAN Sundara has a fantastic overall design and finish.

The Sundara from HiFiMAN is a pleasant headphone. Although not as thick as the earcups, they are well-made and of good quality. The earcups are large enough to comfortably suit the ears. You won’t have to worry about the earcups wearing out over time because they’re replaceable. The headband is very comfy and does not create hotspots on the head over time. By simply adjusting the earcups up or down to meet your head size, the headband can be changed to fit different head sizes. The clamping force is modest and comfortable enough to wear for an extended amount of time. The headphone’s weight is about right, not too heavy like planar magnetic headphones may be. The HiFiMAN Sundara is a reasonably lightweight headphone, weighing 372g, which adds to its overall comfort.

The bass response is superior to that of the 400i and even the 400S. It has a good level and is well extended, as with most planars. Though the bass response is good, it lacks thud and rumble, making it insufficient for bass-heavy music genres such as EDM and Hip-hop. The response in the midrange is even and well-balanced. Both the vocals and the main instruments are well-balanced in this scenario. The treble is smooth, precise, and crisp, however some tunes may suffer from sibilance or sound too bright.

Audeze LCD-4 is the Best Planar Magnetic Headphones in 2021.

The Audeze LCD-4 is one of Audeze’s flagship models. The LCD-4 incorporates extensive research, advancements in performance, and high-quality manufacturing that clearly sets it apart from other flat magnetic headphones on the market. The LCD-4 not only showcases excellent invention and research, it is by far one of the most exciting headphones you can listen to. The only real downside to this headphones would be the price. At nearly $ 4,000, the LCD-4 is well above most people’s budget.

The Audeze LCD-4 pretty much nails it in bass reproduction. Overall the bass is firm, well laid out, and clean. For an open-back headphone, the bass comes out with a good amount and impact. According to Audeze, the bass drops to 5Hz, and after listening to the LCD-4, I tend to agree with their claims. The transition from low to medium is also very natural. The mid-range and the way the LCD-4 reproduces this part make it one of the best in this area. The instruments are well-textured, detailed and realistic. In my opinion, the LCD-4 manages to paint the sound image very well.

The Audeze LCD-4 comes in a black case, which is very sturdy and well padded. Inside the headphones case is a pair of white gloves for handling the headphones (seriously), along a 3m cable that features a 6.3mm termination, owner certified, a flash drive containing the headphones manual in PDF and headphones LCD-4.

The LCD-4 is an open, full-size, on-ear headset and looks similar to its predecessor, the LCD-3, with only minor differences in design. Just looking at this headset, you can tell that the LCD-4 is a beast. The headphones are not very flexible, they do not bend, and the headphones do not rotate as much. However, this is to be expected from such a large headphones.

The M1070 is the best Monolith headphones, with an open-back grille that allows air to travel in and out of the earcups, minimizing air pressure that can cause sound distortion. The open and roomy design also creates a larger soundstage than closed-back designs, giving you a more vivid and immersive listening experience.

The M1070’s design is likewise quite huge and bulky, with 106mm Planar Magnetic drivers and a linear symmetrical magnet set up. The open-backs, on the other hand, make for a more lightweight headset for pleasant listening. In compared to their closed-back cousins, such a design has the drawback of a lack of background noise isolation and more sound leakage.

The M1070 is equipped with replaceable, plush, padded ear pads that are not only comfortable to wear but also serve to block out distracting ambient background noises. The lightweight and padded adjustable headband may be adjusted to fit any head, allowing you to relax and enjoy listening for hours.

The frequency response is likewise broad, starting at 5Hz and extending to 50Khz, allowing you to hear every nuance and tone shift in the music you’re listening to. They’re an excellent choice if you want to hear every note in your music in the manner it was meant to be heard.

The detail recovery is absurd and the soundstage is huge and almost speaker-like. Everything feels tight and in control and there was no genre Aanandha couldn’t be good at.

Oppo PM-3 Closed-Back Planar Magnetic Headphones

Oppo PM-3 Closed-Back Planar Magnetic Headphones (White)

  • Excellent sound quality from planar magnetic drivers
  • Closed-back design for privacy and noise isolation

The Oppo PM-3 are closed over-the-ear headphones. Helmet materials include plastics, plastics, and metals in their design. The hull construction is excellent, solidly built to high standards. The PM-3 is available in multiple colors, including black, white, red, and blue. The headband is padded with foam and a protein skin that covers it. The structure of the headband has a metal steel band that gives it its shape. Aluminum gimbals connect the headband to the headphones. The gimbals allow the earbuds to rotate sideways for easy storage in the case.

The Oppo Pm-3 comes in a box that houses a small box with an Android or Apple cable and a black box with the headphones. When you open the box containing the helmet, there is a nice zippered hard denim carrying case. The hard case houses the small cloth bag with the headphone cable (3m with a 3.5mm to 6.3mm converter) and the PM-3. When paying with the purchase of these headphones, you only have the choice between the 1.2m cable for Android or Apple.

The build quality is quite impressive. There are many pieces of aluminum. The most important thing is that the headband and the joints that connect the headphones and the headband are made of metal. You’ll get a one-year warranty, but the headphones will last a lot longer than that. You will need to replace the earbuds from time to time, but the rest of the earbuds are strong and very durable.

Comfort is not an issue. The PM-3 headphones are much lighter than most flat magnetic headphones. They weigh less than a pound, which isn’t exactly light (especially when you compare them to some regular headphones). Still, they can be considered one of the lightest flat magnetic earphones. The weight is well distributed and evenly. The holding force is not extremely irritating, but it is strong enough to hold the headphones in place. Headband and earmuffs have thick memory foam padding. They are soft and quite nice. The headband is adjustable and the headphones can be rotated. It’s not an easy task to make flat magnetic earbuds comfortable and lightweight, but Oppo has gone to great lengths to make them as comfortable as possible.

  • Our exclusive glass-infused nylon rings are rugged and improve the sound quality.

The Audeze LCD-2 was one of the first headphones to establish Audeze as a leader in the headphone industry. The Audeze LCD-2 Classic is released less than a decade later as a more affordable and accessible headphone. The LCD-2 Classic is now one of the most cheap models in the Audeze LCD family, while still providing excellent quality and a well-built design.

The Audeze LCD-2 Classic comes packaged in a conventional grey cardboard box with foam inserts to keep the headphones secure. The headphones, a 6.3mm jack cable, a USB key, and a certificate of authenticity card are all included in the box. There is no case provided, which is bad, but if you want to travel with this headphone, you can get one separately.

The majority of Audeze headphones have a utilitarian look to them. It’s no different with the LCD-2 Classic. The headphones are an open-back, over-ear design with excellent build quality. They lack the wood rings that are associated with Audeze’s other flagship models, but they still have a high-end feel about them. The headband has two parts: a protein leather substance on one side and a steel upper headband arch on the other. The headband fits snugly around the head, evenly dispersing the weight. Small perforations are incorporated into the headband to provide a breathable sensation.

Memory foam is nicely padded in the earpads, which also include a synthetic leather overlay for enhanced comfort. They’re deep enough that the driver’s ears won’t touch them, and they’re thin enough to give them an angled shape. The earcup housings are constructed of crystal infused nylon, which feels extremely sturdy and should last a long time. As with all of Audeze’s headphones, the earcup endcaps are made of metal and feature Audeze’s design.

Overall, the Audeze LCD-2 Classic has a very smooth, well-balanced, and pleasant sound profile. Starting with the bass, it’s tight and strong. Though the bass is slightly less than that of the LCD-2, it is overall richer, better balanced, and more extended. The midrange is well-balanced, with a heavier emphasis on the low midrange, which makes vocals a little odd and makes it difficult to comprehend the lyrics at times. While the LCD-2 lacked treble, planar magnetic technology has progressed since then, and the LCD-2 Classics now have more. It’s not the best treble, and the texture is a little harsh and gritty, but it’s well extended.

These headphones really live up to their name. The M1060 is monolithic and offers sound quality to match. I should also mention that they are equipped with state-of-the-art technology to give you the best possible listening experience. Monolith M1060 headphones come with special 106mm flat drivers. These drivers are capable of very low distortion even at high volumes. The sound is perfectly balanced to recover an exceptional range of detail from the recording. These headphones offer a frequency response of 10 Hz to 50 kHz and an impedance of 50 Ω.

The bass is the M1060’s biggest asset. It stretches deeply and is not stimulated. It feels natural, shocking, and enjoyable. It’s very tight and doesn’t overshadow the mids. The midrange is well balanced and dynamic. The voices are clear and focused. There are some minor issues with the upper mids, especially the peak around 5 kHz, which can be really annoying. The top end is fairly flat, but not perfectly detailed and lacks a bit of shine. It is neither shiny nor hard. It is present and transparent, but not entirely perfect.

HIFIMAN HE400S Over Ear Full-Size Planar Magnetic Headphone

HIFIMAN HE400S Over Ear Full-Size Planar Magnetic Headphone
  • Sounds terrific on your smartphone or most any portable audio device
  • Superb Hi-Fi Quality with lifelike clarity, detail, extended bass and wide sound stage
  • Only 350g-Long Hours of Comfortable Listening

The HiFiMAN HE400S is an over-the-ear headphone with an open back. The headphone’s build quality is good, however the materials employed in its construction leave something to be desired. The HE400S is mostly comprised of plastic, with the exception of the metal headband and a protein leather headstrap. The HiFiMAN HE400S has a headband that is comparable to that of the HE-400i and the HE-560. The headband includes a superb adjustment mechanism and a variety of settings to accommodate various head sizes. The metal band also serves as a headphone clip and holds the earcups together.

The HiFiMAN HE400S headphones have a great sound. Most people consider the headphone to be an entry-level model, however it has shown to be as good as other planar headphones in terms of sound quality. The HD650 has a similar bass response, while the HE400S offers a tighter bass response. The mid-bass is somewhat enhanced over the sub-bass, giving the entire bass response a punchy feel. The HiFiMAN HE400S’s midrange is among the best in its sound characteristics. The midrange has a nice presence and strikes a good balance without sounding thick. The concentration on the vocals is good enough details and instrument separation. The treble is a touch laid-back and warm, yet it comes out smoothly with plenty of clarity and details.

Among the HiFiMAN headphone choices, this is the cheapest planar magnetic headset. The HE-400S was created with the goal of providing a high-quality sounding headphone at a reasonable price. The HiFiMAN HE400S isn’t particularly unique in the market, but its performance to price ratio makes it a worthwhile purchase.

Fostex T50RP MK3 Professional Studio Headphones

Fostex T50RP MK3 Professional Studio Headphones, Semi-Open
  • Refined Fostex proprietary Regular Phase (RP) diaphragm driver using copper foil etched polyimide film and powerful neodymium magnet
  • Maximum input level of 3000mW to comply with various professional uses
  • Semi-open for flat and clear sound

The Fostex T50RP MK3 is one of the most affordable planar magnetic headphones available for most people wishing to try out an orthodynamic headphone. The Fostex T50RP MK3 has a long history of being praised for its build quality and components flexibility. This is the greatest place to begin altering headphones for a headphone aficionado. The Fostex T50 MK3 is part of a lengthy line of planar headphones, and it looks a lot like the Fostex T50, which was released in 2002.

The Fostex T50RP MK3 is an over-the-ear headphone with a semi-open back. The build quality of the MK3 has been acclaimed by the majority of those who have purchased it, and we were not surprised when we tested it. In the palm, the headset feels quite solid. You’ll also be startled by its weight, which is excellent for a planar magnetic headset at 315g. The earcups are plastic, but they are of decent quality. The headband isn’t the same as it was on earlier T50RP models. It’s better, and it has a slight cushioning that adds to the overall comfort. The headband is held in place by aluminium metal wires linked to the earcups. The wires serve as a mechanism for adjusting the headband’s fit.

The comfort of this headphone is adequate, but earpad changes would greatly improve it. There are various earpad replacement choices available on the market. The Brainwavz HM5 Velour Memory Foam pads are a good affordable option. However, if you want a more quality choice, the memory foam padded Shure 1540 replacement pads (HPAEC1540) are excellent. Other nice earpad replacements that might work well with this headphone are available. Apart from getting comfy earpads, you should be aware that the different pads will change the headphone’s overall sound signature.

When you add in the ultra nano double-sided magnetic planar diaphragm, which acts as a powerful driver to create excellent sound, you have a pair of headphones that will always give the highest quality audio whether listening to your favourite music, TV episodes, or other audio experiences.

Apart from the outstanding sound quality, these headphones are so comfy to wear that you won’t even realise you’re wearing them.

And the ear pads are incredibly soft and huge, so they cover the majority of your ears, but you won’t even realise them because they’re made of this cushiony material.

Dekoni Audiophile HiFi Planar Magnetic Headphone

Dekoni Audio Blue Fostex/Dekoni Audiophile HiFi Planar Magnetic Headphone, One Size
  • Only Foster Sanctioned T50RP MK3 Mod
  • Built in partnership with Foster
  • Comes with 2 sets of Decani Audio ear pads - one hybrid and one ELITE velour pair

After cutting through the technical jargon and trying these headphones for yourself, you’ll quickly notice that their larger soundstage allows for more ambient noise, resulting in sound that’s cleaner, flatter, and open, as if you’re listening to music while standing in a stadium watching your favourite performers perform live in front of thousands of people.

Aside from that, the audio is well-balanced, has a smoother frequency response, low distortion, and a rich midrange, all while maintaining the acoustic output without detracting from the overall experience. This headset has been slightly adjusted to produce an excellent audio sound while also providing long-lasting comfort.

In terms of comfort, one reviewer felt that the overall design was far too large, despite the fact that these headphones are rather lightweight when compared to others of their ilk. Some people dislike the extra bulk in their headphones and find it unpleasant, but if you’re aware that these headphones are enormous to begin with and don’t mind, you shouldn’t have any issues. Another reviewer noted that the maximum sound was on the low side, so if you want to listen to music loudly, you might want to avoid these headphones.

After all is said and done, it’s easy to fall in love with the Dekoni Planar Magnetic Headphone because they’re affordable, provide high-quality audio, are comfortable and lightweight, and have a livelier bass, consistent midrange, and just the right level of treble to create an infectious musical experience that you’ll soon find you can’t live without.

SendyAudio Aiva Black Beauty Series 97x76mm Planar Magnetic Headphones

  • use of traditional craftsmanship, coupled with the selection of high-quality natural solid wood as the material for the housing.

The SendyAudio Aiva Planar Magnetic Headphones feature an ultra nano planar magnetic diaphragm, a stunning zebra wood enclosure, exceptional transparency and clarity, traditional workmanship, a leather carrying case, and a balanced headphone cable with numerous adapters.

As you can see, there are numerous reasons to adore these headphones. Some people adore them because of the high-resolution audio they provide. They may relax in their own homes while listening to their favourite tunes, audiobooks, and radio programmes. But, when it comes to music, these headphones really shine because, thanks to the open design and planar magnetic drivers, you can literally hear each instrument in the headphones.

However, don’t overlook the great level of craftsmanship. The housing for the earphones is made with traditional craftsmanship and zebra wood. Not only does it look great, but it’s also quite strong and durable, indicating that these headphones were built to last.

Although some may disagree, these headphones are a reasonably lightweight design for headphones of this type, weighing only 15 ounces. Some of them are as heavy as a pound and a half, making them incredibly heavy and difficult to wear for long periods of time. Because they are lightweight, these headphones are not at all unpleasant, which is a wonderful feature if you plan on wearing them for long periods of time.

Frequently Asked Questions

What Are Planar Magnetic Headphones?

Planar magnetic drivers, unlike dynamic drivers, feature a diaphragm that is significantly thinner and fully flat. It’s a big, thin film with even smaller wires inside (this is the equivalent of a voice coil in a dynamic driver). Two layers of magnets are placed between this thin sheet. Each layer has an array of tiny magnets that are carefully cut and perfectly placed. They have the appearance of bars. The electromagnetic field is formed when current is delivered to the diaphragm, and changes in current flow cause the diaphragm to move back and forth. The sound is created once more.

How Do Planar Magnetic Drivers Work?

Between two magnets, a diaphragm is suspended. When current is delivered to the diaphragm, it flows through the conductors and produces a magnetic field. The current’s magnetic field interacts with the magnets’ magnetic field, causing the conductors in the diaphragm to move, and the diaphragm to move at the same time, producing sound.

The magnets in planar drivers have an equal isodynamic magnetic field to ensure that the current flow and force exerted on the diaphragm remain constant as the diaphragm moves.
