Review: Surptisingly good actually, and two bits of adhesive tape make them 10x better - They are amazingly good for the price, definitely much better sound than my old AKG K271 MKII (which aren't just V-shaped, they are N-shaped, I can't believe I've spent at least 6 years in them. Yeah, and they cost about 2.5x more than the Hifimans). I think these Hifimans are the really flat apart apart from being a bit bassy and having a peak at a few kHz that can make the "S" sound in vocals annoying. But YOU may like it, and if you don't, like me, it is a very easy fix, described at the end of the review. The sound is unbelievably detailed with and without the mod, but without the mod the vocals also an feel a bit odd, like there is normally a minuscule amount of echo or sustain, and here there is none, so it can sound oddly dry in a way. Like the diaphragm can start and stop so fast it causes the sound to have way less sustain than you are used to. I guess it could be that most people including me listen to music through dynamic drivers only, whether it's speakers or headphones, and then they add a little bit of sustain to everything. The mod diminishes this effect a little, turning it from annoying to actually good. I never had planar magnetics before, so this could be the effect all planars do have, and in itself it's worth the price as it is really interesting to experience. It makes brass and percussive instruments sound crazy good, like you are there. They are surprisingly comfortable when you are upright, but can slide off if you are lying on your back and didn't tighten the headband more than what feels best when sitting or standing. The build quality is OK, and much better than it looks on the photos. The earcups do have a vertical swivel even though it doesn't look like they do, just the point of rotation is within the black part of the headband. And the forks are metal. The cable is really nice and thick, and is probably like a balanced cable all the way except for the plug. These headphones are easy to disassemble (sometimes a little too easy, the grilles for example), and there is a plenty of upgrades available, including 3D printed and buyable (headband, earpads, grilles, cables, etc.). But you DO need a headphone amplifier/actual soundcard/Bluetooth DAC/stationary hi-fi equipment that has a headphone output, as a phone or other portable devices meant for ordinary headphones can be too weak to drive them properly and they will sound a lot worse than they otherwise can, even at the same volume. They definitely sound good from Creative SoundblasterX G6 and Douk U3, so you probably don't need anything unreasonably expensive. Other than that I can't really think of any reason NOT to buy them if you want wired headphones that sound good, have great soundstage, are easily repairable/moddable and are cheap. The $0 mod goes as follows: Just remove the earpads and put adhesive tape as seen in the picture. The earcup has a plastic ring that is rather flexible nad has four hooks that point outwards. The easiest way to get it off is to reach for the ring through the earhole and try to lift it where one of the hooks is. The tape has to be between the second most rear and fourth most rear magnet, and should not extend out beyond these magnets (and put it on the magnets, NOT on the diaphragm, this is just to make the sound go less directly into your ear hole). Just leave one rear gap and three front gaps. And leaving about 5mm from the top and bottom makes it as detailed as it was without the nasty sharp "S" sound, and just a very, very small amount bassier). You can adjust the tape length to your liking of course, the amount shown works best for me. Also be careful, do not touch the diaphragm, and be aware that the magnets are quite strong, so that if you use a ferromagnetic tool to trim or apply the tape, it can be attracted to them suddenly). Also be aware that the earpads have front (thinner) and back (wider) sides, and do one ear at a time to avoid mixing them up.
Review: Good Build quality and Solid Sound. - I bought these a a Christmas gift for my grandmother and tested them against my Monolith M1060s ($250 to $350 at the time of writing this, and also very well worth it if you can afford them as well) to make sure they were what I'd want to gift her. The HEs aren't as deep sounding and they're a little lighter on the build quality, but for 2.5 to 3x cheaper, they're totally worth it. The lows could use a bit of a boost in comparison to the M1060s for my taste, but other than that they're worth what I paid. The cups are plastic, but the joints and open-back grills are all metal. The ear pads are a mix of synthetic leather on the edge and velour on the face. It's really nice, honestly. My grandma is mostly gonna use them for her electric piano anyway, so I tested them on another keyboard she gave me and they really shine. Along with that, from classical pieces to pop to heavy metal, they're really clear and pretty well defined between 20hz to the 17-18khz that I was able to hear, which is right at what most people should be looking for and what's described in their specs. I like the extra weight of my M1060s, but the Hifimans will most likely be better for my grandma specifically because they're lighter. They're still very well built though, I have no doubt after handling them. I also want to mention that the foam that they come packaged in becomes a headphone stand once pulled out! I've never seen that, and haven't really seen anybody mention it, but it's nice to see the small features like that really bring the whole package together. I think that for a hundred or so bucks, these are definitely a grab if you plan to sit down and really listen to what you're hearing.

## Features

- What is a planar headphone? What are its benefits over other designs? Planar headphones feature conductive layers that cover nearly the entire diaphragm, resulting in significantly lower distortion than conventional dynamic headphones.
- Acoustically Invisible Stealth Magnet Unlike the sound waves created by a conventional magnet, the special shape of Stealth Magnets enables the waves to pass through the magnets without generating interference. HIFIMAN’s advanced magnet design is acoustically transparent, dramatically reducing wave diffraction turbulence that degrades the integrity of the sound waves. The reduced distortion yields pure sonic output that is accurate and full-range.
- Durable Connections The headphone’s drivers are protected by a newly designed casing for enhanced durability and protection from the elements. A dual-sided high-performance 3.5mm cable is packaged with a 6.35mm adapter for maximum compatibility with a wide range of devices.
- The HE400SE’s high sensitivity makes it the perfect match for low-voltage sources, including portable hi-res. audio players.
- Maximum Comfort for Hours of Listening Pleasure Thanks to its newly designed adjustable lightweight headband, the HE400se remains cool and comfortable for hours, even in excessively warm weather.

## Questions & Answers

**Q: Do these HE400se come packaged with a better cable now?**
A: Ordered mine on Black Friday, and it did not come with the better cable. Seems like you get lucky or you don't as to if you'll get it.

**Q: How are these when compared to beats?**
A: Better in literally every regard. Beats are slightly better than overpriced steaming garbage, while retaining the overpriced aspect.

**Q: How do they compare to Sundara?**
A: Sundara sound better. He-400se it's a good entry level into planars I would say.

**Q: How do these compare to the HE400i?**
A: Most people (at least myself & professional reviewers) think the HE400se with the new Stealth Magnets are a decent bit better of an overall performer than the older HE400i 2020 (& ESPECIALLY vs the OG HE400i), but they're also harder to drive amp-wise to get them to their peak, & thus said superior audio quality/sonic presentation, so... 🤷‍♂️

If you already have a solid amp (anything with >≈ say an ESS Sabre ES9280C DAC + amp chip) I'd definitely get the HE400se's even if they're both the same price. OTOH if you don't already have a decent amp, then it becomes MUCH less cut & dry if similarly priced. (The HE400se is usually SIGNIFICANTLY cheaper though, making it basically ALWAYS the better choice tbh).

### ⭐⭐⭐⭐⭐ One of the Best Sub-$200 Headphones Available...!!!
*by C***S on December 18, 2022*

Should you want to venture into the world of 'Magnetic Planar' headphones without breaking the bank, then the HIFIMAN HE400SE Stealth Magnet headphone is a great place to start...!!! I bought mine in May 2022 and have been extremely pleased with their quality-build, comfort, and overall sonic performance...!!! You will notice small nuances in the music that weren't there before when using other dynamic headphones in the past... The clarity and detail retrieval is amazing, especially when considering the price point...!!! Hifiman is a well-known company that produces planar magnetic headphones, that come in a wide range of prices, so you're dealing with a quality brand from the get-go...!!! Before I jump into its outstanding features, you should understand one aspect of planar magnetic headphones versus dynamic headphones... Magnetic Planar Headphones require a little power to drive them to their optimum level/performance... You can't just plug them into your cell phone or laptop and expect them to sound great...!!! They require some extra power to perform to the best of their ability... I run mine through an iFi Zen DAC V2, which is a DAC/Amp that puts out 380mW-Balanced & 280mW-unBalanced, which is more than enough to drive these headphones to the maximum...!!! There are numerous portable DAC/Amps on the market that can drive these headphones, so it's not as bad as it might sound to people new to the Hi-Fi hobby... As to sound qualities - (1) Bass is well-detailed, well-controlled, and overall is pretty neutral in its tonality (2) Mid-Range is clean, highly detailed, organic/natural sounding... (3) Treble is slightly emphasized, but never too bright or harsh, with good clarity and detail retrieval... The soundstage is wide with accurate imaging overall... These headphones are neutral and well-balanced, so they are great for long listening sessions, yet you can also use an equalizer to tune them to your own personal tastes, if you like... At its price point, I believe the HIFIMAN HE400SE headphones outshine the competition with (1) High Resolution (2) Fantastic Clarity (3) Overall Balanced/Neutral Tuning (4) Top-Notch Price-Performance...!!! At approximately $120 dollars, it truly punches above its weight in every aspect you can think of... My friends are amazed when they try out these cans...!!!
