I compared rings on both cups and it doesn't seem like it's broken. Maybe the ring is not holding the grill tight enough.

I'm definitely going to ask Hifiman and see what they have to say about it.

I concur though that the logo pieces that secure the yokes to the headband are way too weak, it's a blunder on Hifiman's part. They are coming out with new planars next year though, so we might see a complete design change that fixes these things.

I just tried mineral oil and it definetly got better.

Too bad it's so difficult to untighten the screw because I'd really like to have them even more loose.

 

Good advice on how to swivel, I'm going to be very careful when swivel from now on.

 

 

Thank you both for your response.

So I've got HE-400s and I want to listen to FLAC music but also have virtual surround for PC gaming. If I get something like the Xonar DG, then hook it up to an o2 amp, is the sound card going to make it useless to have FLAC files? If I understand the product description correctly, it says the max output is 96Khz. So that means that even if I have FLAC I'm going to hear the music at a lower quality, compared to coming straight from USB to DAC? What is the difference between the 196Khz on the Essence compared to the 96Khz on the Xonar DG? I was hoping to listen to nothing less than 320kbps, so is that completely separate from the 96Khz/196Khz?

 

Also, I was considering skipping the sound card and going USB -> DAC/AMP and using razer virtual surround but I wasn't sure how that would match up against Dolby. If anyone else has experience with this type of thing and HE-400s let me know.

Don't worry too much about that. 16bit/44khz is all we humans need.

What may make a difference in SQ is the quality of the DAC and amp on the Essence vs DG's. The max sampling rate really doesn't matter. As long it's higher than 44khz, you're fine.

Don't worry too much about the file bitrate either. Above 320kbps the differences are pretty much negligible, if there's any at all.

I would just stick with 44khz for cd music and 48khz for dvd. Bumping up will introduce errors that may or may not be audible. The exception of course is if your flac files are 192khz/24bit or 96khz/24bit then you want your settings set accordingly. Is HD tracks worth it...well there's science behind that as well and to my understanding it's theoretically unnecessary.

If your ripping your original Cd into flac then it should be 44khz.

Thank you for the responses, definitely cleared a lot of things up for me and I feel like I can make the correct purchases now. Next thing on the list is to find a good place to download 320kbps that doesn't cost an arm and a leg, but that is another story.

post #15231 of 18107
If 320kbps mp3 or similar is all you want then Spotify Premium might be a good choice at $10/mo. Just be sure to download the content to offline mode, turn off the volume leveling, and put your quality rate to the highest setting.

Usually FLAC is in the 600-1000kbps region, depending on how complex a song is.

why turn of volume leveling?

I don't know why people complain that EQ has been talked about a lot on this thread, frankly it makes more difference to the sound then anything else you can do for the HE400, only other things that are talked about are amplifiers, pads etc. All of which have also been talked about a lot as well. This is the nature of a thread with 1015 pages..... But EQ will make the biggest difference with the HE400 as well as the pad mods.

Now then, as for sibilance, I get that you've been trying to argue about sibilance being a part of the vocal midrange, but sibilants are essentially to be treated as overshoots, and not as fundamental tones or harmonics.  Their center of energy vary from around 4khz (f), 8khz (th) or even 10khz (s, t).  People tend to complain about the s and t range with the HE-400.  This is all naturally speaking as well.  Hot recordings which tend to over-emphasize the treble region for the sake of false clarity make the th and s,t region even worse.

 

HE-400 also tends to have much less upper midrange compared to a lot of more neutral headphones on the market.  They're relatively flat to around 1.5-2khz, but take a nosedive starting around 3khz.  A headphone with much more upper midrange in comparison like the LCD2 ( a good 5-6db more in the 3-5khz range) is also way less sibilant in comparison, and that's because it doesn't have a Mount Everest centered around 10-12khz.

EQing and velour pads is the clear easy fix for the HE-400's for those trying to get the best possible sound with no major investments.

 

Pad Mod is, IMO, the only thing that saves the pleathers from the trash heap. They are just bad stock. TMRaven, where is the data showing frequency response with/without foam spacer rings? There seems to be some consensus that glare is an issue (but fixable with simple mods). I would have thought that improving the response of the 1 khz region would have had a positive impact on natural vocal sibilants.

 

I don't have the convenient link anymore, but I've heard some examples of slicing up vocals to support intelligibility / limit sibilance (by listening to the same recording over and over with narrowly defined bands), and, I can say, it is very much true that the midrange is a critical part (if not more), to controlling problems with sibilance. Maybe I'll find the link again sometime. But quick googling makes it obvious that recommendations for sibilance cutting (by people smarter than I) are all over the place - 1.5 khz - 7 khz and higher. The HE-400s scoop out many of the frequencies known to be sources of fatigue and sibilance, so I continue to find the disagreements here interesting. "Air" created by harmonics allowed to spill way into the high frequency range might be a convenient target, but I am flat not convinced its the only place one needs to look for sibilance problems.

 

Then again I've been clear that I pay attention to my recordings also, and can't fault the headphones for every negative listen I've had - some recordings just weren't mixed that great.

while eq'ing might be the best thing for the 400 as of now i am very curious about obtaining some of the new audeze fazor difuzers and seeing if they help with phase at all

post #15235 of 18107

hey guys,

 

sometimes I periodically experience a brief (like 1sec) distortion... doesn't seem to be a problem w/ my source file. what do you think it is? could it be my amp? lol

So if I paid $10 this month and downloaded a bunch of songs, then canceled my membership do I lose all those songs?

It's not the headphones.

Yes lol. It's like paying for Netflix or library membership. Only good while you're paying for it. I think it's rly worth it tho

I might have to take back my statement about the spacer being a culprit for the 1khz peak, some of Purrin's later graphs show differently.  Either way I did notice a change in the response of the HE-400 around 1khz when going from stock pleather to stock velour.

 

But either way the HE-400 has famously scooped upper midrange and is famously considered sibilant.  So the midrange is ultimately not the biggest factor in its sibilance problems-- regardless of recording.

It seems only the HE500 driver reacted to the foam spacer measurably. 

 

Although if you really A/B the HE400 measurements with/without the spacer, you can pick up subtle changes still. The spacer pushes up 1kHz slightly, pushes down 2kHz slightly, and seems to have a more significant shelf around the upper treble (though that is debatable as upper treble measurements tend to be unreliable). The mids/upper mids difference, though subtle in terms of amplitude, would still have an impact because they are fairly broad.
