If you are planning to own a pair of planar magnetic headphones but don’t wish to invest too much or simply just started your journey, the HE4XX is definitely an ideal choice to consider.

Partnering a matching amp with your HiFiMAN HE4XX will be a good idea and finding the right one for the job will require us to learn more about these wonderful headphones. When we have gathered enough information and data about the HE4XX, we will then share with you a list of the best headphone amps to go for.

Sound Characteristics of the HiFiMAN HE4XX

Even though the HiFiMAN HE4XX has an affordable price tag, it still won a few accolades over the years, thanks to its amazing sonic performance for the money. A headphone amp will help bring out its full potential since the HE4XX has a low sensitivity of 93dB. The low impedance rating of 35 Ohms does give us a lot of headphone amplifier options to choose from. We will need to filter out most of these amp choices by considering the price point of the HiFiMAN HE4XX. Matching an expensive or high-end headphone amp is not really worth it.

It is already incredible for a planar magnetic headphone this affordable with such a level of sonic performance, and yet it is still comfortable to wear. HE4XX is not very tight and the earpads felt nice on the ears, you’ll probably be able to wear them for hours without feeling discomfort. The HiFiMAN HE4XX uses open design as its principle and the noise isolation capabilities are almost non-existent which is as expected. There are sound leakages as well and these may annoy people who are near to you while you are listening to your music via the HE4XX.

The bass performance is light and tight, and this comes to us as no surprise but what we didn’t expect is the accuracy and how detailed the low-end is. HiFiMAN HE4XX is capable of producing detailed low frequencies which are clean and clear, blending in nicely with the upper registers. It never once sounded boomy, still, the bass reproductions do have a lack of impact. The HE4XX doesn’t really bring out the sub-bass like the original version could, but it has more details and textures though, so it will be up to your preference to find which is better.

The HiFiMAN HE4XX stereo imaging is good, the soundstage on the other hand is not as spacious as we have come to expect from an open-back design headphone but overall it still sounded natural. The high-frequency reproduction of the HiFiMAN HE4XX is rather highlighted and can be too bright sounding at times. Still, it doesn’t reach a level of cringes that is unbearable. There is a sense of realism when it comes to vocal reproductions which are amazing for an entry-level planar magnetic headphone. The sound rendering of the musical instruments ain’t bad either.

All in all, you are getting a lot of sonic performance and value from the HiFiMAN HE4XX at such an affordable price. The overall sound quality is good for the money even though it has its flaws. HiFiMAN HE4XX won’t be suitable to play bass-heavy soundtracks and is not really meant for analytical audio enthusiasts. They are also more suited for music playbacks and not really great for movies or gaming. You can now take a look at the list of the best matching headphone amps which we have prepared for you below.

These are some of the very best entry-level headphone amps with most of them closely priced to the HiFiMAN HE4XX and will be worthy of your time to audition them.
