Hifiman HE400SE (Stealth Magnet and Non Stealth Magnet 2021) International Open Back Planar Magnetic Headphones
This is a different model compared to the newly launched HE400SE in China which is a downgraded version of the popular HE400i V2020, the international version will be using stealth magnet instead which is also applied onto Hifiman famous flagship Susvara, hence the different pricing with non stealth Magnet version (BECAREFUL!)
Thanks to HIFIMAN's planar technology technology, the HE400se has a higher sensitivity, coupled with impedance of only 25 ohms, not only surpasses the old generation of planar headphone. HIFIMAN HE400SE are also easier to drive even connected to the smartphone at 70% of the volume.
Confirmation from HIFIMAN is that the international version of HE400se will be using Stealth Magnet Technology found on the SUSVARA TOTL model to allow sound waves to pass through with less interference, netting an improvement in reduced distortion and purer sound.
