Unforgettable First Step
The HIFIMAN HE-400I headphones hold a special place in my heart as they were my first serious foray into high-fidelity audio. Despite upgrading to the Sundara later on, memories of my experience with the HE-400I still bring a smile to my face. These headphones deliver exceptional sound quality, courtesy of their planar magnetic drivers, offering precise highs, lush mids, and impactful bass. The open-back design creates an immersive soundstage that draws you into the music. Even after moving on to other headphones, the HE-400I remains a cherished memory, making them an unforgettable choice for any audiophile's collection.

Solid planar cans
I own several cans but for day-to-day listening I keep grabbing these. Soundstage is among the best of the cans I own. Really great entry point into solid sound and construction. Only negative is these feel big, and sometimes I find them to feel top heavy.

Great headphones and great sound
The sound and comfort is great. I will have to replace the wires since one of them feels like the plastic beneath the braided outside cord has broken. Sound is unchanged though.

For the price, these are superb
The sound from these is amazing. The build quality seems fine- which at this price I’m okay with. The only complaint is the odd audio effect that happens if I speak while these are on, which I can only describe as an echo of my own voice that I get. It must be related to their size & shape. Makes them unusable for double duty such as listening to music and then taking a zoom call. But I bought these for music, and that’s where they shine, so I’m giving them 5*

good for the money
I just wanted to say that I got these to replace a pair of AKG K7XX I've had for years. I wasn't sure what to expect, being totally new to planar.
They're very close. They're in the same league. I'm not good at the describing the differences.
The headband on my AKGs were strapped up, plastic cracking, creaky worn out. These new Hifiman's are comfy, sound good, but I've not worn them in yet to really review the sound.
Only lost a point because the 1/4" adaptor is trash, or the 3.5mm jack is too small? I'll want to get a longer cable to have that as an option as the AKGs was massive. I could actually walk away from the desk with that one. This one ties you to the desk.

2 bad things, but good if it's just a one off issue
The good is, simple, they are great sounding, super clear, and fun to listen too. I am not sure if it's a one off issue, a common issue with Planar headphones, or a common design issue with these headphones. And I can't say, cause these are my first Planar Headphones I have ever owned, so take the review with a grain of salty sand.
The bad, the cups that came with mine were not refined at all, with strings and stuff hanging off both of them. Neither of the cups were flat, but wavy, which isn't an issue normally with me, but it's just an added note to the bigger issue. Whenever I change the way my face faces too fast, either left or right, or if tilt my head towards my shoulder on either side, I hear hard plastic crumple noises. Like the sound you'd hear with a cat toy, like that hard sheet plastic that feels like it was designed to make all the noise in the world. This is the reason I have an issue with these headphones. And it compounds cause when it starts making the crumple noises, it takes you out of it, out of the audio and the music, and it's really so god damned annoying. It also happens whenever I have a fan on in a room, if it's just moving the air. The other part is sometimes i have a fan blow from the side, to cool me off, cause where i live electricity is mad expensive, and fans are cheap. This is the reason i think it's just a one off issue with my headphones that i received. I also notice there is a considerable amount of the crumples when this happens too, on the one side more than the other. This makes me believe it might be an issue with all of them, HE-400I's, or even potentially with Planar Magnetic styled headphones. I can't say i know at this point, as i only have ever used these ones.
If my issues were one off, and only within a select and limited amount. Then yes I'd recommend these to anyone and everyone, and I would rate this 5 stars. IF they are not, then no, no recommendation to anyone, and i'd lower it to one star.

GamerFrom93Thank you for sharing your experience. I had a problem with Sennheiser 280 Pro "mechanical noise" that found me, very sadly, having to return those headphones - I needed extreme sound isolation, and those headphones actually blew my mind with the quality of the sound that reached my ears... excepting the 'scrunch, squish, graagh' sound of the cable echoing inside of the cans when that (coiled) cable would slide ever so slightly across, say, my shirt, or pants. UGH... I have yet to own or even listen to planar headphones. Should you have any additional comments, I'm very interested in reading them.

AKGmanBased off my experience, it seems to be a one off issue cause Z Reviews did a video on the the HE-400i on the headphones and he didn't complain about any par, and I'd recommend watching that for sure.
The cable that comes with the headphones i got were really short for desktop use, at least for me, but no noticeable scratchiness to it, or any cable noise when it touched anything. The stock cable's connection to any 1/4 inch adapter fits very poorly. By that I mean, with pretty high certainty, that the stock cables 3.5mm end is slightly too small as it doesn't properly sit in any other 1/4" adapter i have, and know to be working properly. By that i mean it cuts audio for one of the cans, and can be kinda fixed by doing the "damn my ipod is going out gotta kinda push and pull the jack till it sits so i can hear out both ears again" shuffle thing.
These headphones are definitely not in the idea of sound isolation in the sense of noise canceling, as they are super open, and i can hear when my cat is walking around behind me in my room, kinda long nails hitting hard wood. If you mean sound isolation in the sense of being able to identify an instrument or hear something, or just general audio clarity, then ya, tots great. If you were to give these headphones a try, I'd say prepare for buying a longer cable or different cable for sure.
