HiFiMAN Truly Delivers: HIFIMAN HE400i Planar Magnetic Headphones

HIFIMAN HE-400i

HiFiMAN doesn't build your average pair of headphones; they build works of art to truly introduce you to your music. The HiFiMan HE-400i planar magnetic headphones let you hear every minute detail in your music like you've never heard before. The HE-400i feature some of the finest headphone engineering and craftsmanship available today to bring you a pair of headphones that, once you put them on, you won't want to take off.

HIFIMAN HE-400i

An added benefit of the HE-400i headphones is that, due to their highly efficient operation they can be plugged directly into your smartphone, tablet or any other output device; it is important to note that to take full advantage of the HiFiMAN HE-400i a headphone amplifier is highly recommended. Don't let your ears toil away with a mediocre pair of headphones when you could be basking in the glow of the HE-400i headphones from HiFiMAN!



Lose Yourself in Your Music

HiFiMAN engineered the HE-400i headphones with full size planar magnetic drivers which produce warm, balanced sound. The advantage planar magnetic drivers offer over your average headphone drivers is that they cover a larger surface area to deliver outstanding sound detail and spaciousness. Their incredibly natural timbre combined with the open back design make these headphones sound like you're sitting in the crowd at a show.

Listen in Luxury

With the HE-400i headphones, listener fatigue won't be a problem. These sleek over-ear headphones offer FocusPad ear pads, beveled ear pads made from a mix of pleather and velour to improve both comfort and durabililty. The newly designed headband provides a greatly improved pressure pattern. They are also 30% lighter than comparable headphones. The HE400i headphones offer you best-in-class comfort.

Quality Connection

The quality of your headphones doesn't matter if you don't have a connection to match. HiFiMAN designed screw terminal inputs into each ear cup for a secure connection. Each connection uses a separate ground lead for each channel to significantly reduce unwanted crosstalk between channels, improving your overall sound quality to optimize your listening experience.

Great value on sale for a great headphone

The following review is for HE-400i, which is a part of the bundle you are viewing.

I would totally recommend this product for someone looking for a step up in their headphone setup (coming from an ATH-M50). Especially at the sale price ($299), there really isn't a whole lot that beats them.

The sound quality is amazing, it is almost like stepping up again from to the M50. While it is not extremely open, there is a mod to replace the grills on the drivers with wire mesh that I will probably do that apparently fixes a lot of this, giving it a wider soundstage. The sibilance is not noticeable at all, even at high volumes. Note that these will need an amp and will greatly benefit from a DAC (I own the Schiit Modi 2/Magni 2).

The packaging was very nice, came with a leather box that flips open to reveal the headphones within. Shipping was very fast, arrived exactly when expected.

Ef2c

The following review is for EF2C, which is a part of the bundle you are viewing.

I am impressed with the combination. Got the phone first then the amp tonite. It came without the orig transformer. 16 volt AC.
I am using a 12v 2A trans. Not sure if few volt less would make a big difference. Somehow my USB input is not working yet. When plugged in and note book says usb installation ready, i lost both the phone out put and zilch from the usb. Anyways i will try to sort usb out later on. At this moment i am enjoying the analog output. Listening to this fellow. Playing tribute to Shadows.
