Heaphoneaddict, is there any change in current from the various tubes used in the WA6? I currently have some 6FD7, 6DE7, and 6EW7s. Seems that the 6FD7 have higher gain than the rest, but i'm not sure if the current would be any higher.
I'm not sure, sorry.

I ordered mine during the first week or two in December, and received them on New Years Eve. They do feel like they have the star pattern under the pad, so they must have been one of the first of the newer batch and the reason it seemed like they took forever to arrive! I wonder if there's any felt in there, as they were still a little too bright the first 250+ hours or so, but they're "all better" now.

are you saying that lcd2 could be the oem brother of the he-5? it looks very similar too.

in any case, if was good of the lcd2 people for not having to beta their product with end users.

lets not open that can of worms again.


I don't think the HE5 is really Beta testing, like most products it is evolving based on peoples response. There is always a demand for a certain version of a particular headphone.

So I am assuming the star shaped pad inside is a good thing, I was wondering why things seemed a little less edgy when I got my replacement! I am actually really happy from this little mod, and I guess its good that the company is adjusting to feedback of the customers, this is always a good sign! Also good job to head-direct, the replacement is excellent, no cracks or rips *knock on wood* lol... Great to have these back, I missed them... Cheers,

Do not confuse driving headphones loud with driving headphones properly. HE-5 do not distort. Ever. You can drive them to the loudness of small speakers (with adequate and powerful enough amp), but they will not distort. The distortion you are hearing is your headamp's inability to give enough current to HE-5 on that volume level (like you trying to bench 10-25 Kg beyond your max - you will probably move it, but it will be more like jerking than lifting). The fix? Mo' powa!

IMO build quality is OK. The weight, cable shortness and long term wearing comfort are my issues with HE-5.

Hmmm interesting take here. Why would you like 2 watts for a pair of headphones?

Specs on the HE-5 are not very clear, however lets take another headphone from the market as an example:

Beyerdynamic DT880 Pro (I chose this because Beyerdynamic usually gives good info on their headphone's specs):

Quote:
Nominal impedance. . . . . . . . . . . . . . . . 250 Ω per cartridge
Nominal SPL . . . . . . . . . . . . . . . . . . . . . 96 dB SPL
Nominal T.H.D . . . . . . . . . . . . . . . . . . . . < 0.2%
Power handling capacity . . . . . . . . . . . . 100 mW
Power handling capacity = 100 mW When listening you usually don't feed the headphones with 100 mW unless you want to explode your ear drums. So why in this world would you like 2 W for a pair of headphone drivers?

I have a question for some of you guys using the HE-5 with extremely outrageous powerful amps, have you tried to set maximum volume with some pair of headphones connected? Did the drivers crack/explode?

Note: There are exceptions, as you can see for Fostex TXXRP series, where they have Power handling capacities up to 3000 mW or 3 W, so you won't blow up your headphones.

Most headphone amps put out 1 volt or less, so cranking up the volume is going to induce low end distortion when pushing magnets in an ortho.
Not sure why a dynamic K-1000 sounds better, other than the fact that it likes lots of wattage.
The Woo Audio puts out < 1 watt depending on the load. Pumping up the volume isn't going to help you. My Luxman P-1 puts out 1 watt at 32Ω, so it's a good match for me.

Do you have a more powerful amp that you can try with them?
EDIT: There is a mistake in what I wrote up there. I was comparing volts to watts directly, because I thought he said 2 Watts, and so as we are mising the amperage I can't covert the voltage to power. However I checked on Head direct's site and the specs say:

Quote:
Output signal strength: up to 15 Volts at 32 Ohm
I wonder now how many watts it does output.

Even so I made my point, which is that you only need a few hundred mW to power headphones to ear splitting levels.

Has the LCD2 been officially released yet? It is definitely not the OEM brother of the HE-5 because the LCD2 is made by a smaller company in the US, and the HE-5 is made in a factory in China. Also, if they are not Beta testing with their customer's, it's because up until (possibly) now, their have only been a couple of prototypes floating around a Head-Fi meets. Alex told me that the headband was something that is temporary until they find a better design and vendor.

P=I X E where P is power or watts, and it is equal to E, which is voltage, and I, which equal current.

The voltage output of an amp directly correlates with how many watts an amp puts out. Most portable amps put out something like 375 mW, or 1/3 of a watt, and home headphone amps come closer to a watt which is usually rated using a 32 ohm load (like a Grado, for example). But the HE-5 is not a dynamic headphone, which consists of sending a signal to a coil which is attached to a paper or composite driver (think speaker) and the driver moves and flexes to produce sound.

This is not to be confused with an Orthodynamic headphone, which consist of strong magnet being charged, which cause a material (somewhat like an electrostat), to flex and and stretch to produce sounds. In an ortho (like a Quad ESL speaker) the magnets need a lot of power to move around the strip.
Also, this is not to be confused with an electrostatic headphone or speaker, that requires a special amp to "charge the stators to a certain bias (580-600V, for example), which then move the mylar (or similar material) in between the stators to produce sound.
Besides the use of magnets, instead of stators, the other main difference is that an electrostat headphone requires and electrostatic amp, and an Orthodynamic headphone can be used with a dynamic amp, but one with enough power and inductance enough to power the powerful magnets. The better the magnets and the better the processing of stretching the material, is what is going to change the sound signature of the headphones.

I'm pretty sure that the LCD2's and the HE-5 use different specs when coming to those to items, which is all a mater of designer's choice. They are
not common OEM's.

In my opinion (take into consideration I've only heard them in a meet environment), but the LCD2's are slightly darker in their signature. Sort of like the difference between a pair of Stax 404's and Omega II's MK 2.

It's everyone's choice what kind of signature that they like. The other choice is, when are the LCD2's going to be ready for mass production.

I might be a little off on the technologies, but that's the basic gist of the comparisons.

I am very happy to be an unofficial beta tester myself, if that is why they consented to sell these babies for $599 instead of $999 like they planned, that's like giving away the EF5 and $100/US IMHO.

Maybe I am one of the lucky ones, but I am completely satisfied with the sound, comfort and build quality of the HE-5's, qualified by my pending (edit; got 'em) earpad replacement!
post #1497 of 1668
Do the HE-5 have serial numbers on them?
May be a way of recognising which are the earlier and later productions so people know what to expect sound wise (since the newer ones have been tuned differently).

Im not sure whats taking the LCD2 so long, maybe they are just taking time to perfect it, but it will sure be interesting once its released. Im still holding my breath (turning a bit blue now! )

I find myself bobbing my head more with the HE-5 (happens subconsciously) and I feel more involved in the music. It makes the music sound more realistic and closer than the HD800 without sounding closed in at all. In fact, as good as the HD800 is in this regard, sometimes I prefer the soundstaging of the HE-5. Overall, the HD800 is the more transparent headphone but the HE-5 are more fun to listen to the majority of the time.

Just want to reiterate how good a value these things are.
I love how every time hd800 gets compared with headphone it always loses and author always prefers the other can

my b22 is set on high gain for balanced turned it all the way up one day they lived only had it up for about 30 seconds though.

haha were you wearing them on max volume? You got what I wish I had... balanced HE-5 on B22... :slimy drool:
