## Description

From the manufacturer Acoustically Invisible Stealth Magnet About HIFIMAN Founded by Dr. Fang Bian in 2007, HIFIMAN is widely regarded as one of the leading manufacturers of high-performance headphones and portable audio products. HIFIMAN is especially known for its critically-acclaimed Planar-Magnetic headphones that feature state-of-the-art driver technology. The company also designs and manufactures world-class dynamic in-ear drivers which have also garnered awards and rave reviews Unlike the sound waves created by a conventional magnet, the special shape of Stealth Magnets enables the waves to pass through the magnets without generating interference. HIFIMAN’s advanced magnet design is acoustically transparent, dramatically reducing wave diffraction turbulence that degrades the integrity of the sound waves. The reduced distortion yields pure sonic output that is accurate and full-range. Frequency Response: 20Hz-20kHz Impedance: 25Ohms Sensitivity: 91dB Weight: 390g High Sensitivity The HE400SE’s high sensitivity makes it the perfect match for low-voltage sources. The sound is rich and pure without the need for a bulky amplifier. Maximum Comfort for Hours of Listening Pleasure Thanks to its newly designed adjustable lightweight headband, the HE400se remains cool and comfortable for hours, even in excessively warm weather. Durable Connections A dual-sided high-performance 3.5mm cable is packaged with a 6.35mm adapter for maximum compatibility with a wide range of devices. The headphone’s drivers are protected by a newly designed casing for enhanced durability and protection from the elements

Review: Here is what you need to know - Its not a easy headphone to drive. You need to have a good amp to actually enjoy the headphone. Keep that in mind. The headphone sounds out of this world. No questions about that. If you are looking for something you can listen at home attached to an amp and a decent device ( lg phones, IPAD or any decent laptop with a jack). Then go for it. This is a cheap planar but believe is premium where it matters. If you looking for something more versatile as in just plug and play device without amp then, Phillips SHP9500/9600 is your go to.
Review: Best planar headphone in this price range - Primarily I didn't want to buy this because of two things . 1. The flimsy wire given with the box 2. QC issues with Hifiman. But I did take a chance. And amazed. This is a pair of wonderful cans. Wire is not that flimsy according to other reviews, but not good also. The seller added an extra good wire , that was a bonus. I've not faced any QC issues till now. But one amp/dac is needed to unlock hidden magical sound. I'm using Shanling UP4, which is not that great of a dac/amp. But it does it's job. I would recommend Fiio Q3/Ifi Zen Dac 2 for better performance. And also if possible buy a balanced cable , you'll in the moon. Take care of your cans. Adios!

## Questions & Answers

**Q: Do these HE400se come packaged with a better cable now?**
A: Ordered mine on Black Friday, and it did not come with the better cable. Seems like you get lucky or you don't as to if you'll get it.

**Q: How are these when compared to beats?**
A: Better in literally every regard. Beats are slightly better than overpriced steaming garbage, while retaining the overpriced aspect.

**Q: How do they compare to Sundara?**
A: Sundara sound better. He-400se it's a good entry level into planars I would say.

**Q: How do these compare to the HE400i?**
A: Most people (at least myself & professional reviewers) think the HE400se with the new Stealth Magnets are a decent bit better of an overall performer than the older HE400i 2020 (& ESPECIALLY vs the OG HE400i), but they're also harder to drive amp-wise to get them to their peak, & thus said superior audio quality/sonic presentation, so... 🤷‍♂️

If you already have a solid amp (anything with >≈ say an ESS Sabre ES9280C DAC + amp chip) I'd definitely get the HE400se's even if they're both the same price. OTOH if you don't already have a decent amp, then it becomes MUCH less cut & dry if similarly priced. (The HE400se is usually SIGNIFICANTLY cheaper though, making it basically ALWAYS the better choice tbh).
