Entry-level king of planar magnetic headphones

Cup style More information
Open-back headphone designs are often higher-performance but have poor noise isolation and leak sound. Closed-back designs provide better noise isolation and leak less sound.


Wearing style More information
Over-ear headphones sit over your ear and surround your ear with a ring of padding. On-ear headphones are padded but rest on top of your ear. In-ear monitors are worn inside your ear canal.


Driver type More information
Speakers and headphones use a device called a 'driver' to create sound. Different types of drivers have different strengths and weaknesses, but can all produce great sound. Common varieties include dynamic, planar magnetic, and electrostatic.

Planar Magnetic

Amp required More information
Some headphones require the power of an amplifier to reach comfortable listening volumes.


Connectivity More information
Connectivity refers to the method in which the headphones connect to the audio source. Headphones can be either wired or wireless.

HiFiMan HE400se: The Entriest Level Planar - Written review by FC Construct. 

Hifiman HE400se Entry-Level Planar Magnetic Over-Ear Headphones | is happy to bring you the global version of the Hifiman HE400se Over-Ear Planar Magnetic Headphones which features Hifiman's unique stealth magnet design. The stealth magnet design is unique to the global version and is not including in the version available in China. The stealth magnet helps reduce wave diffraction turbulence and reduces distortion levels to barely audible levels.

Acoustically Invisible Stealth Magnet

Unlike the sound waves created by a conventional magnet, the special shape of Hifiman's stealth magnet enables sound waves to pass through the magnet without any interference.

Hifiman's advanced magnet design is acoustically transparent, reducing wave diffraction turbulence which would lead to a degradation of the sound waves. The reduced distortion yields pure sonic output that is accurate and full-range.

Maximum Comfort for Your Listening Pleasure

Thanks to the Hifiman HE400se's newly designed adjustable, lightweight headband, the HE400se remains cool and comfortable for hours, even in the most extreme heat.

The Hifiman HE400se planar magnetic headphones also come equipped with a newly designed driver casing for enhanced durability and protection from the elements.

Durable Connectors

The Hifiman HE400se ships with Hifiman's dual 3.5mm headphone side connectors and single-ended 3.5mm on the amp side with a 1/4" adapter. If there was any flaw with the HE400se, it would definitely be with the cable which we would recommend replacing when you have the chance. As the HE400se uses 3.5mm connectors, there are countless aftermarket cables that will do the job.

Title Description
Sensitivity More information
Headphone sensitivity measures how loud a pair of headphones will be at a given signal strength. Headphones with higher sensitivity ratings will produce louder sounds than headphones with lower sensitivity ratings. It is measured in dB SPL (decibels of sound pressure level) per unit of power (typically 1 milliWatt) or sometimes unit of voltage (typically 1 Volt) from the source at a frequency of 1 kHz.
Total Harmonic Distortion (THD) More information
When driving headphones at high volumes, it is possible for the diaphragm (the ‘speaker’ inside the headphones) to be unable to move fast enough. This leads to distortion, manifesting itself as crackling, popping or the alteration of musical notes. Most headphones will fall below 1% THD.
Frequency Response More information
Headphone frequency response refers to the frequency-specific sensitivity of the output. Frequency responses show the range that headphones are capable of reproducing—a graph shows which frequencies are accentuated over others. The ideal range covers the audible sound range of 20 Hz – 20 kHz.
