    HIFIMAN HE-400i reviews

    HE400i Single-Ended Planar Magnetic Headphones is rated 4.0 out of 5 by 7.
    Rated 5 out of 5 by from Amazing Sound Quality These headphones have amazing sound quality. They have extreme precision and balance in sound in heard of in this price range. The highs, mids and bass don't step on each other at all. Truly a magnificent sounding headphone. One caveat is that they are not very loud without a headphone amplifier. The detail and richness really come through with a great amp. I tried all the high end Sennheiser (650,700) and the AudioQuest Nighthawks, and even the Mcintosh 2k headphones and to me none sounded even close to as detailed and as balanced as these. If you are going to spend you money on a high end mid-fi headphone this should be it.

    Rated 2 out of 5 by from Sound was OK, but they literally fell apart in my hands The build quality is lousy. They sound good and are quite comfortable, although with weak bass. After owning them for about 5 weeks, I took them out of the case to put them on and they literally fell apart in my hands. The brackets that hold the earpieces on, the flimsy plastic fork-shaped pieces, cracked and fell apart as I put them on. If you look at the images, you can see that this is a manufacturing failure. Poor materials and poor design. This failure has been documented by numerous other people online.� Don't waste your money on these. In fact, after this experience, I won't be purchasing anything made by Hifiman ever again.

    Rated 5 out of 5 by from Absolutely ! I will forgo the typical audio review for this headphone as there are several reviews of this particular headset, easily accessible on-line elsewhere, done in a more comprehensive and more articulate way than I could manage. With that in mind, I will say that these are my first foray into Planer Magnetic Headphones and I think these cans have let me delve into the realm of high end sound and provide a sound that is clean, accurate, and abundant, likely the product of planer magnetic sound. I will say, I do take some issue with some of the reviews on-line as they may leave you with an impression that the HE-400i's bass is lacking, as they did me. After listening to these for almost two weeks, my opinion is the bass or low end of the sound is accurate, clean, and it's there! Hitting the low notes with ease and abundance, very addictive. It's by far the best bass of the cans I currently own. The only conclusion is that those who made such implications were afraid that some people might be disappointed as they may not be used to cleaner bass. With that in mind, don't mistake clean bass with lean bass. As in hitting all of the low notes with articulate and accurate sound, leaving the listener able to discern notes; a bass that is full but stops short of interfering with adjacent frequencies and complements and completes the notes played. For instance it does not cover up the ring of a kick drum or the impact/snap and reverb/echo of the snare or tom, a bass that is coherent. Anyway, to go on, the other frequencies, i.e. middle, high, and presence aspect of the phones are of an equivalent quality and all together create a coherent and addictive sound. I would like to preface, to those not used to good quality equipment, in this case the revealing nature of these cans. Your sources are paramount, and as I have found out, if the recording is of poor quality, you will hear it, so much so that it's not all that pleasant. On the other hand, if your sources are of good and superior quality, then like me, it will be such a good time that you will have a hard time putting these headphones down. I was able to pick these up during a Christmas sale. They were a steal to say the least. Of course, this is all my opinion but I'm not disappointed in these cans and the big question is, knowing what I know now, would I buy them again.. Absolutely! Purchased Christmas 2015 - updated model with an updated headphone cable connector from traditional coax F type connectors to 2.5 mm mini plugs.

    Rated 5 out of 5 by from Goodbye HD650's, goodbye Dynamic Drivers, hello Planar's. After claiming the HD650's the KINGS of the Sub $1000 headphone price range, All I can say is that things have changed. After selling my 650's a few months ago due to lack of time for listening, I decided to re-purchase the 650 since the price drop. Before the purchase, I decided to ask around and look, and sure enough, forums were filled with comments suggesting a NEW Big Boy in town, under $1000. So, I took the plunge, and sure enough I am convinced. After 100 hours of burn-in and pairing the 400i with the Fostex HP-A4BL Dac/AMP all I can say is WOW, A must own for someone who prefers the balanced yet warm-ish sound profile. Trust me, you will love it, feed it high-fi Flac's and they reproduce the recording very well, Goodbye HD650s and goodbye Dynamic Drivers, Planar Magnetics are the future, thank you HifiMan.

    Rated 4 out of 5 by from Amazing Sound, Amazing Price Really at any price these are fantastic headphones. I spent a long time looking for sub $$headphones. Reading reviews on hifi websites, going to my local hifi store and listening to different headphones. These really take the cake. They easily compete against the next tier up of quality. The sound is balanced, sharp and detailed. I took these back into the hifi store and plugged them into the McIntosh MHA200 headphone amp and compared them to the Audioquest Nighthawk, the Sennheiser both 650 and 500 series and the McIntosh headphones and felt that these sounded better and cleaner and more balanced than all of those. Headphones at this level are about quality of sound and how fun they are to listen to. I find myself having a lot of fun listening to these. They can drive even from the iPhone 6 plus and the iPod classic that i have but they really shine with a headphone amplifier. I use the Schiit Fulla but plan on upgrading to something with tubes soon. Even with the less expensive Fulla i think these sound fantastic!

    Rated 2 out of 5 by from Should be 5 stars While I would love to write a glowing review about these headphones, and say I would recommend them to my friends, I simply can't.� The Sound quality is spectacular, A relatively noticeable V-Shaped sound with an outstanding soundstage.� The only reason I can't recommend these is a static popping issue I have with the left driver.� I will be contacting customer support for both B&H and Hifiman to see if they can do anything to remedy the issue. As I said, it should be a 5 star product.

    Rated 5 out of 5 by from I get to re-discover my music collection with new ears! I am pairing the HE-400i with the Dragonfly Red USB DAC, running sound out of the USB port on my laptop. I am playing FLAC files with 16bit, 700+ kbps quality. These are amazing headphones. I am listening to Gramatik, a techno-funk artist, right now and the Hifiman HE-400i headphones are showing me layers more definition and sound beyond what I could hear with my earbuds, car stereo, etc. As can be expected, these produce sound with dimension and purity that my very nice earbuds couldn't even touch. Plugged straight into the laptop audio jack, they sound good, but when I play them through the Dragonfly Red, they are incomparably better.�The music is so much deeper, bigger, more satisfying. I can hear the textures of sounds from string instruments like never before.� The bass isn't very strong compared with the treble. It sounds smooth and accurate, but I feel like it could use about twice as much bass. I think I can address this with a good equalizer. That's my only critical comment. I will update this review as I learn/experience more.
