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.




HIFIMAN EF-100 Hybrid Vacuum Tube/USB DAC Headphone Amplifier

The HIFIMAN EF-100 Headphone Amplifier Offers an Incredible Listening Experience

The HIFIMAN EF-100 is a powerful hybrid headphone amplifier and integrated amplifier. Housed in its compact chassis lie three independent amplifier sections: a vacuum tube input stage works as a shared preamp, a Class AB headphone amplifier, and a Class T speaker power amplifier. Benefiting from vacuum tube technology, both headphone amplifier and power amplifier sound warm, smooth, detailed and musical. Working as a hybrid headphone amplifier, EF-100 can produce a 2w output under a 32 ohm load so it can easily drive many high performance headphones. In addition, EF-100 can also serve as a hybrid power amplifier to drive speakers of moderate to high efficiency. In power amplifier mode, the amplifier output line is fully independent from the digital amplifier line used in the headphone amplifier. Driven by front stage’s vacuum tubes, EF-100 combines the warmth vacuum tubes are known for with the high efficiency of a digital amplifier. It is the best of both worlds. When EF-100 is used as a power amplifier, it can give 4.5 watts per channel so it can drive HIFI speakers of moderate to high efficiency. At last, with its versatile design EF-100 can bring music to life from a variety of sources for both headphones and speaker applications.

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.
