post #14311 of 20208

I like animals and all that.... Just not those creepy little things.... Seriously I mean.... WOT is a spider? It is not normal....

 

Anyway on HE400 related matters.... I settled on an EQ for my HE400, it is surprising actually how you can make these things sound almost 100% non sibilant / tizzy / harsh.... Just by EQ'ing the right frequencies by the right amounts....The treble to me now sounds natural... Definately a massive improvement over the graphic EQ... I went back to the 31 band foobar EQ as an experiment and yep.... After an hour or so my ears were hurting again.... To the guy who switched back to graphic EQ.... I strongly recommend giving ElectriQ another chance because it can work miracles with these headphones, Just need to do it using Sinegen and frequency sweeps then test a few songs and leave it alone.... Set up a few presets for good / bad quality recording and then do not touch it again. Do not change it depending on what song you are listening to or this can be a fast downward spiral into EQ tweaking insanity :biggrin:

hahah well, it's almost the same as with the headphones guys, think of the "Non-audiophile reactions to high-end headphones" thread... :smile:

i'm getting a weird static on heavy bass notes, i started noticing a couple weeks ago.  it sounds very much like digital static, but i can only hear it on my HE400's, none of my other cans or any of my hi-fi zones.  changing cables/usb ports etc on the DAC/amp did nothing.  so it seems to only happen with my 400's, but its very, very digital in sound and only happens on lower bass, and i can only hear it when it's otherwise quiet (bass drops).  it's really bugging me, any suggestions?  is there something to check for this in the cans themselves (although i can't believe that because of how digital it sounds)


Known causes of static:

 

1) dust on your drivers (unlikely if you've not messed with mesh screens or kept your earpads on) *Never happened to me but has to others

2) Loose connection on one of the earcups - Re-Tighten connection *Happens to me quite a bit and creates static / cut outs

3) EQ settings being used to boost, rather than cut frequencies - lower EQ gain

4) Amplifier  / Preamplifier clipping - adjust gain settings, or turn the volume down

 

and what I would personally wager as most likely:

 

5) Clipped Recording

 

I check for clipped recordings with Audacity. You can drag and drop the audio file in to the program and have it highlight clipping. There is no cure for you if it is there, but the clipping does sound exactly like static through the HE-400s. I also use waveform seekbar with Foobar. Usually I can tell that a recording is likely to be clipped just be looking at the waveform.

Just got mine today and theyre my first planar headphones, do they benefit from burn in?

Yes, defiantly.

Brain burn in, definitely, the planar sound is one that surely takes time to get used to. Actual burn in, even if I did believe in such, is said to be very minimal with planar magnetics.

Not only brain, but their sound will change in the first 20 hours. I did compare my brand new HE-500 with the used one, the new one had more trebles in the beginning.

I do believe in brain burn-in too.

Thanks for the quick reply. As expected , I like the overall tonality. The sound sig is tailored fit to my taste. Thanks to this thread, it helped me a lot in choosing HE400. Happy camper here:gs1000smile:

Its been the most with the he400 to me. Every other dynamic, has been easy to get used to its signature. The he400, took a while. Had to not listen to any other hp for a few days/ weeks to adjust. Then going back to dynamics, well I'm ruined so to say. Still like the re400 and magnum, but...need more planar!!!

I just noped over and over, that spider is HUGE. (That's coming from somebody living in Australia)

...but I have to say that's the prettiest spider I've ever seen :P

Yes I would agree that brain burn in is very important with the HE400... probably more than any other headphones I have owned. Also mods and EQ.... Brain burn, mods, EQ = win

I've had my Emotiva Mini-X A-100 for a couple days now, so I'm going to share some impressions with the HE-400.

First of all, I had to figure out how to make an adapter. This amp has common ground, so the stock TRS jack of the Hifimans will work with an adapter. This kind of adapter will cause major problems with speaker amps that don't have common ground, so check with someone who knows what they are talking about if you try to make one like this for a different amp. For example, this won't work with a Topping T-amp. 

My first attempt was to chop the female end off a 3.5 mm extension cable from Radioshack that I had laying around. I cut off the outer rubber layer, removed the flimsy foil shield, and stripped the ends of the L+ and R+ wires. The ground wire was bare, so i covered it with some of the outer layer that was left over. As you can see, it's pretty ghetto looking (not helped by that tape I put around it at the junction). However, it worked just fine. My biggest complaint was that the wires were very thin and fragile. 

 


Note that you only need to connect one ground wire to either one of the negative terminals on the amp. L- and R- are connected inside the amp, and would be connected again at the sleeve of the TRS jack, so there is no need to have separate wires for them. 

I put together a more solid adapter last night. I can't solder, so I used a Switchcraft model 1230 TRS female jack. It has screw terminals inside, so I just had to match up the terminals and wrap the wire ends around the screws and tighten them. This is very convenient and puts DIY adapters in the reach of anyone IMO. I used wire that I took from inside a Canare Starquad cable. In retrospect, it would have probably made more sense to order individual strands of wire than to take apart a cable, but whatever. Separating the individual wires means I can see which is which and don't have to do continuity testing with an ohmmeter. The other advantage of this adapter is that it's a 1/4" female, so I can use my 3.5mm to 1/4" adapter with 300 ohm resistors inside. 

 

 

 

The Emotiva is obviously overkill for the HE-400. I'm ok with it. It's cheaper than almost every SS amp I can think of beyond the Magni and O2, which is why I got it. And because my Little Dot MKIII was clipping at high volumes, so I wanted MOAR power. MOOAARR! :evil:

Without the resistors, there was some noise floor. Not enough to ruin the experience for me, at about the level of ambient noise in my house. I could definitely hear it when things were dead silent in my listening room, but with the heating system running, washing machine on in the other room, etc. it was much less noticeable. With the resistors, the noise floor is totally gone on the HE-400. I can't even tell if the amp is on. 

Each time I first used my two adapters, I plugged in my Nuforce IEMs before my HE-400s to make sure there weren't any shorts and that I matched the terminals correctly. Without the resistors, the noise on the IEMs was awful. With the resistors, there was about as much noise on the IEMS as there was with the HE-400 and no resistors. 

Without the resistors, I had digital volume at around -10 to -20 db and the volume knob at 9 or 10 o'clock on the HE-400. With the resistors, I have digital volume at -0 db and the volume knob at 11 o'clock to noon, which is about what I expect from any amp. So the volume knob is very usable. 

On to the sound compared to my Little Dot MKIII. The first thing I noticed was increased definition in the bass. Complex bass lines in electronic music became clearer (like this: http://www.youtube.com/watch?v=CP9r4g4qfbc), and the bass tightened while also gaining impact and snap. Extension was about the same. The sense of visceral texture in the midbass and lower midrange, the crunch and crackle of synths and guitars, improved noticeably. The Little Dot's bass sounded bloated and smeared after listening to the Emotiva. 

Moving up the spectrum, the midrange became cleaner and faster. This amp really highlights the speed of the HE-400 IMO. The treble became a bit less smooth, but not offensive at all. Again, more speed and articulation. The Little Dot seemed to slightly blur the whole frequency spectrum in comparison. The Emotiva increased the size of the soundstage a bit, and increased separation and layering even more. On Daft Punk's RAM, for example, image placement became substantially more 3D. In general, I wouldn't say I'm noticing more details, but they are clearer and easier to pick out, especially sounds like synth layers in the background of mixes. 

I also tried using the Little Dot as a preamp. It mostly sounded like I was still listening to the Little Dot, except there was obviously no clipping. It did however increase the usable range of the volume knob.
