5:00 I wholeheartedly agree and i really like how you've phrased that "we exaggerate" when describing how wide the soundstage of a Headphone is. When getting into the Hobby i was chasing soundstage and hearing about the HD800 made it seem like that headphone would give me this out-of-body speaker-like experience. So when i finally tried it out, i was dissappointed that it didn't. Good thing that you mention this. Later i did actually buy an HD800 and still own and love that headphone. And honestly, if you want a hyperrealistic experience with headphones, the HD800 will deliver that, just not with music, but definetly with games.

It was my first Hifi Headphone and indeed it is really good and competitive for its price.

Great review. Can I drive this with smartphone?? Despite having 90db sensitivity.

EF400 for desktop only use or Cayin RU6 double amped with my current desktop amp, adding portability for IEMs and saving $? I use HE6sev2 about 30% of time and MEST mki 70% on the go. I realize the subjectivity of my question, so perhaps it boils down to if you feel the sound quality of the EF400 is truly head and shoulders above the RU6 or if they are somewhat similar.

Waiting for 560s vs 400se comparison 🔥🔥

Between this and he6 sev2 Hifiman offers the best product for certain price point

Wish you had asgard 3. cuz its a warm lush discrete powerful amp. might pair well with 400se. I'm torn between getting 2-300 amp for my 400se or a used hifiman ananda that can be driven off my phone.

Talking about Hifiman, have you tried the Ananda Stealth? I have been wondering how far away is it from the Arya SE after receiving the stealth treatment.I am deciding between either DCA Noire, ananda or just save enough for the Arya or Clear og.

Andrew from the headphone show compared it to the HE X4. Very similar frequency response and sound. He concluded that they sound so similar that the decision should come down to aesthetics cable comfort price etc I have the X4 and with a bit of EQ it's good enough for now until I get an endgame headphones.

I had them for a while, and I find them hard to drive (harder than Senns 650), and I agree that they do scale up. However, the biggest revelation is that I've recently got Beyer DT 1990 Pro, and much to my surprise 400SE put them to shame in terms of clarity, attack and decay, and upper treble performance. 1990 Pro sounded unpleasantly shrill, veiled and lazy compared to 400SE. Incredible. They were both driven and compared with several power sources, and the most difference was noted with FiiO K7.

Loved the EF400 but recently started hearing some background hiss in High Gain NOS mode. I've talked to others who also had this problem. It could be a unit by unit type thing where most are fine. I'm going to hold out for hopefully an EF400+ type upgrade that includes some Digital inputs like Optical and Coaxial. Right now the EF400 is strictly for desktop use

I think you should try the er3se or er4 I find in terms of technical ability it can rival many kilobuck iems not even mentioning the great tonality

can 170 mW of output will drive this properly?

I have a JDS Labs Element II, i guess it should be enought for the HE400SE but not completely sure, can you tell me if my Element II will run it fine ? Very revelant review ty very much btw

so an hd600 becomes a 1500 dollars pair out of an otl?

It come close to sundara?

John 3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. Isaiah 53:6 All we like sheep have gone astray; we have turned every one to his own way; and the LORD hath laid on him the iniquity of us all.

Great headphone but not for me , So bright and the Sssss on every vocals is OMG unbearable
