post #10141 of 15503
What concerns me is not the color variance it is the resistance variance . How can the same product vari almost 50% and be the same sound .
As I only have one pair and the stated amput is about 45 ohms how many others have gone to as high as 70 .??

For those worried about their HE6 being almost piano black, try putting it under an incandescent light; it should turn purple. I was stumped as well with my pair when I got it a while back, under neon light or even natural light it would remain very dark and almost piano black. But indeed, the magical purple would appear beautifully under incandescent lighting.

 

 

On another topic, has anyone besides me ever used LCD3 pads with their HE6? I've been using them for over a year now as it really opens up the soundstage and corrects the timbre and realism quite a bit in the highs; however, it also becomes quite brighter and looses out on slam and impact in the bass. I'm considering bringing the LCD3 pads to a tailor to sew on a microfiber suede on the portion of the pads that rests on my face, hoping the pads will alter sound in a way to increase warmth and tame the highs a bit.

u have a foto of the fit of the LCDpads on the HE6? i tot this pad is slightly bigger in diameter...

 

i tried the alphapads for a while, then i switched to Jmoneydenonpads and i tot the sound is more open.

Now i am experimenting with the JmoneyBeyerpads..quite open too. 

Not gonna put the alphapads back. :P

Maybe it is, maybe it isn't.  What model Fluke do you have?  How old? 

 

If you really want to measure the impedance of a wire, or a switch or other low impedance path, here is a technique that will allow you to use a standard volt meter and a little bit of set up.

 

NOTE/DISCLAIMER:  DO NOT DO THIS WITH YOUR HEADPHONES!!!!!

 

Get a decently regulated DC power supply.  5 Volts, for example.  Should be able to source at least 500 mA.  We will only be drawing ~ 100 mA.

Get a resistor.  For this example, lets use 50 ohms.  Doesn't need to be a precision resistor, but it should be a power resistor.  You'll be dissipating a little power.  Around half a watt, so your resistor should be 2 Watts or better.

Measure the resistor to the best precision you can and record that impedance.  My example resistor measures 49.97 ohms.

Connect the resistor to the wire you want to measure.  Nice solid solder joint preferred.

Connect the wire to one side of the power supply, the resistor to the other.  Polarity doesn't make a difference.

Put the meter in volts DC mode and measure the voltage across the resistor.  Should be very close to 5 V.  Lets say we measure 4.985 V.

Now, put the meter across the wire under test and record the voltage.  Use the millivolt range for best accuracy.  Lets say we measure 9.8 mV or 0.0098 V,

Turn everything off and break out the calculator.

 

Calculate the current through the wire and resistor:  I = V / R or 4.985 V / 49.97 ohms = 0.0998 A or 99.8 mA

 

Now, calculate the resistance of the wire:  R = V / I or .0098 V / 0.0998 A = 0.098 ohms

 

You should be able to get a much better estimate of the resistance of the wire with this method than with just a meter.  Even though you subtract out the internal resistance of the meter and the test leads, you STILL can't trust most DMM's to give accurate readings below 1 ohm.  The currents used to measure the resistance are just too small.

Hello Everyone,

 

I received my HE-6.  I assume they are real, but I think they may have been operated on, maybe?  At least I hope this is not what the factory produces.  They have the right characteristics: Very demanding on the amp.  3 o'clock vs. my normal 10 o'clock HD650 spot.  This was expected and my LD MK6+ is set at low gain, which I know would have to change if I keep the HE-6.  They are clear and very detailed in their sound, but the headphone itself is noisy(physically noisy, like pops in the plastic when moving).  The inner retaining ring is not flush, even protrudes beyond the plastic cup where there are no screws.  This makes me think it has been opened.  Others have mentioned you can see gold through the outer grill, I cannot.  There is a black piece of material preventing this.  Viewing from the inside with the cushion removed certainly reveals a gold driver, though.  Also, these are definitely BLACK no matter what kind of light they are viewed under.

Let Me know if these photos match what others have, please.  Thank you.

I get that purple tint under my incandescent lights, BUT they are neodymium doped glass bulbs, so the violet end of the spectrum is quite enhanced.  True "natural" lighting (the sun) gives no such illusions of color...  But, if you like that color, load up your house with Nd glass bulbs!  :)

Here's an upload from last year of mine. I simply put the HiFiMAN disc inside the audeze pads. It's finicky to get all 4 tabs in the headphone, but once it's done it stays put very nicely.

@Karllin - If I'm seeing this correctly, and it is what you have described, it definitely doesn't look right to me. Note what I have highlighted in green and red. It should be flush all the way around, like what i highlighted in red.

Man, that just looks like it would be a vice grip on your skull lol. Is it comfy during long sessions?

Interesting....  Might have to give that a try!

 

@Karllin I just checked and, as brunk described that rim is (on mine) an should be flat all the way around.

Tampering?

Lol I'm not so sure about that :tongue_smile: 

 

The impedance variances, paint finish variances, and now this is really making me question what, if any, type of QC HifiMan is putting the HE-6 through. I'm not too pleased at the moment, given the price of the HE-6. Atleast, they sound good awesome though...

I have since added the HD600 headband cushion and wrapped the beyerdynamic headband sleeve around it to make my HE6 almost as comfy as my HD800.

 

The LCD3 pads are super comfy and squishy. I think I may even prefer the fit of my HE6 with all this padding on my head as it feels like a substantial headphone whereas the HD800 sometimes feels weird after long use.

@brunk and Potterma,

 

Thanks to both of you.  brunk thanks for the great illustration!  Yes.  It is as I expected.  I am not sure why it is not flat, as it should be. The biggest problem is because the ring is not flush, it moves in and out while wearing which produces a plastic on plastic noise.  I can speculate either fake(I don't think so), bad QC(I hope not), this pair has been repaired or modified(likely).  I will contact Hifiman and see if it is possible some of their rejects escaped their factory.  That does happen over here, or if they have refurbished some.  Their factory is near, so it is possible.

 

The sound is what I would have expected.  I must say they certainly bring out any flaws in the source, unlike the HD650 which seem to mask them in extra bass.  The music is kind of naked and pure.  There is bass and very deep, but very tight and not emphasized at all.  The mids and highs seem perfectly accurate. I am no pro, so not able to describe well what I hear, but I can imagine with a more powerful amp these would be unbelievable, especially for classical.  I just listened to some piano, cello, and violin from a 24/192 source and nothing is missing.

 

I appreciate everyone's help.  I do not think I am dealing with fakes, but likely a pair that have been worked on or rejects.  But I will say, from what I have seen in the past day, both here and elsewhere, Hifiman could do a much better job at manufacturing consistency.  The color has changed from part to part, I am sure.  I saw a purple hue pair, live.  Mine are not. And some have no black material between the outer grill and driver, some do, it seems.  Mine do.

"QC" is the elephant in the room. At some point, one of us is going to scream "Who let that thing in here?! And why is it sitting on my side of the room?!!!"
