Very satisfied with the purchase
The Hifiman HE400i are my first planar magnetic headphones, and I couldn't be happier about my choice. The sound is punchy and at the same time clear and balanced. There is only one thing that really matters, the HE400i needs at least 50 hours of burn-in time (Hifiman even recommends 150 hours). You can't get into the world of planar magnetic headphones any cheaper (and better for the price).

Really good headphones
I have never listened to planar magnetic headphones before. These are awesome. The build quality for $150 is great and the sound is like no headphone, iem or anything I've ever heard before. I'm consistently looking around for things entering the room when it's just the great seperation and clarity of the background vocals or a xylophone or something. It definitely can't be run from a phone (maybe if you have a v60 or something) unless you want to sacrifice the bulk of what makes these great. I'm using the 4.4 balanced connection on the ifi zen dac and I'm really happy. Like others have said, if you are on the fence or haven't listened to planar magnetic headphones then get these.

Comfortable and greats sounding
Love these, sound great. Adding in the bass boost from my Zen dac also works nicely when I want it. My only negative is the cups get a little itchy and pick up loose hair like crazy.

Was there much or any sound change at all? any pad changes I've ever done I have ruined my headphones. (except my fostex T50RP)

Yes I think it adds bass note density without destroying everything else. Mids are a little recessed. Overall I think the pad swap definitely made them sound better than worse... but easily more comftorable.

Nice and Clear (and probably overkill for my use case)
Got these to replace some AKG's with a broken headband. Sound great for the price but I am not the best judge of that as I suffer from chronic tinnitus. These are my everything headphones as I cannot justify anything more expensive as they all sound alike to me.

Like Stroking a Seal
Promised to ship 04th Feb, shipped 29th Jan arrived 15th Feb in Estonia. Build: Sadly it doesn't have the fanastic old box 400i came with. Hifiman claims it's an upgrade since it's environmentally friendy but know what, I would've kept the old box, this one's propably going in the trash and I'll find a nicer storage solution for it. Box is not bad, it's just not the fantastic leather one. Build wise its VERY well built. Everything is solid, thick strong. Far cry from what it was back when they cost 500 bucks. Now it's 130 and better in every way. The cable tho could propably be used as a lifting spring on a f350 truck cause it's so rigid and coiled. I didn't know cables could get this bad. Sound: Comparing it to my akg k95's and fidelio x2's. Running them through ifi zen dac mostly. I've been listening to x2's ever since they were released and I couldn't imagine sound getting better. I tried them on for a while, playing some tracks and after half an hour, just as I was typing my initially slightly dissapointed impressions to my gf I heard it. I heard a detail in one of my favorite songs I've never heard before. It had a strong and loud presence and it felt like I was kicked in the face. And I was sold. Those headphones are well more detailed, have far greater instrument separation, really good soundstage compared to x2, bass is there, it shakes your eyeballs but it is clean and it is smooth. Everything is clean and smooth! It really does feel like stroking a seal. Just slick, clean, no fuzzies but still soft and feels good. A steal at 130plus shipping plus customs and a month's wait. It even sounds good through Valhalla 2, against the common "OTL and planars bad mkay". The sound is way different compared to solid state tho. I'd like to listen to the 400i more but I'm straightening out the cable and once parts arrive I'll make my own goddamn cable. If you want to try planars, you can't go wrong here. Especially for the money.

excellent sound! for only $145???
HE-400i is my new daily driver. The clarity and detail are amazing, bass is great. I like them a lot better than hd600, better than he4xx. The cable sucks, so I am using periapt balanced connection; ifi Zen DAC to Aune X7s (i know it's not truly balanced, it's just temporary setup). It sounds great!!

Good sound for the $, but the cable awful and adapter is defective
For the $ paid I am impressed with the sound. It is nice to have an efficient pair that sound good even through my cell phone. However, the 1/4 inch adapter and/or the 3.5mm jack do not have good tolerance. I could not even use the 1/4 inch adapter included, it cut out if I as much as breathed. I happened to have an extra 1/4 inch adapter which works OK if I do not stand up and move around at all. (Checked on three amplifiers, it is not the amp socket). This sloppiness is compounded by the fact that the cable itself is very stiff and helps move the jacks going into the amp. I hope the headphones themselves have longevity. Again, for the price they sound very impressive IMO it is just disappointing that the requisite hardware is defective.

Are very comfortable
Very good precise sound. The sound is clear and very bright. The lower parts of the sound could be a bit stronger. Cable is too stiff and inconvenient - to exchange.
