A little more bass weight and treble sparkle than the DT880/250 making an overall very engaging, enjoyable sound.

Something just doesn't sound right, is 600Ohm 2005 Manufaktur? What amp do you use?

I plugged the 600ohm Manufaktur one and the 250ohm Consumer one both into my Fischer amp and can confirm the Manufaktur does sound more transparent and smoothed out.

Most of my previous observations still stand but the Mids one if different now. Mids seem to be more fleshed out with the DT880 600ohm than the 250ohm Consumer through my Fisher amp. Also bass seems to be better controlled with tube amplification.

I'm using my new DNA Sonett tube headphone amp.

I received the 600 ohm direct from beyerdynamic USA. They are not Manufaktur but look identical to the 250 ohm 2005 version. The only difference is the packaging which has a label saying "600 ohm version audiophile model".

I'll have both at Can Jam and you can hear for yourself

i also have the dt880 600 ohm manufaktur series and believe me i had a hard time choosing 250 ohm and 600 ohm between them...
imo i think 600 ohm is much more linear,quieter and more transparency than 250 ohm...
mids is more properly smoothed out and it's became 1 of my favourite cans....aside from my akg 701 recabled and hd650 recabled...
it will be matter of time my dt880 will be joining the group

Never heard of that amp.
Read my post on butchered non Manufaktur 600Ohm models. I owned regular 250 and 600Ohm Manufaktur version so I have a pretty good idea on how they both sound.

Not surprising, it's a new amp I'm launching at Can Jam

yes I read your post

The 600 ohm I have measure 605 ohm for left channel and 607 ohm for the right.

The most noticeable difference I hear between the 600 and 250 ohm versions is the 600 ohm has less vocal presence, making the music sound less engaging to me. I prefer a "you are there" presentation to vocals.

The DT990/600 ohm is similarly engaging as the DT800/250 ohm. Vocals are a tad less prominent in the mix while bass is stronger.

[..] one 600Ohm DT770 that I got did not have dampening caps installed, and the other one had it just on one driver.

I asked Peter Grooff(beyer headphones product manager) and he was really surprised that one of the 2 drivers had a missing cap

I got the 600Ω drivers directly from beyer as spare parts and they have perfectly matched drivers(my multimeter reads 616Ω on both)

I tried the stock 250 then 600 on the same source within a 10 mins break, and the 600 was way more refined in the upper spectrum...like faster drivers/less distorsion.

as Peter Grooff put it :

I expect the 32Ω version to sound less transparent as the 600Ω version. Headphone systems with lower impedances usually have a slightly heavier diaphragm + coil causing it to react slower to impulses…systems with higher impedances do the opposite.

Quote:

The transducers of the 80Ω versions are stronger and more powerful, a bit more mid accentuated. The 250Ω version sounds more smooth and voluminous. Normally the 80Ω is louder than the 250Ω version. The DT 770 PRO 80Ω has a straight cable (3m), it is for the usage as studio monitor headphones – especially for instrumentalists. 80Ω systems are ideal for powerful reproducing of low-frequency material f.e. coming from a bass guitar. The stronger system and thicker membrane provides punchy and clear bass sound at high levels. The DT 770 PRO 250Ω system with its lighter coils sounds more smooth and analytical. The application in studio would here be more in a mixing situation to analyse the whole mix.

but I understand the 770 shares the same drivers w/ the 990, but the 880 is not too far...from what QQQ more or less demonstrated.

I wouldn't necessarily say this. To me, I prefer the sound of the 250 ohm DT880 over its 600 ohm variant. Of course this is personal preference.

For the DT990, I strongly prefer the 600 ohm over the 250 ohm version.

Imagine his surprise if you'd let him know that one pair had no caps at all, on both drivers.

I can see that out of the tube amp, may be GS-1 and GLite due to insane transparency make 250Ohm too bright, and tubes wool it down a bit. All I can tell that 600Ohm version is super smooth (honey to the ears) out of my SS amps and 250Ohm was harsh and brittle.

 

[Zombie_X]

I plugged them into my Zune and they both are the same volume? That's odd. The 600ohm should sound far more quiet than the 250ohm version, but they are the same volume...

Maybe it is the tubes which are transparent and the SS amps that are harsh

That means they are both the same impedance. Check them with multimeter.

 

[Zombie_X]

How would I check them with a multimeter? I don't want to open them up..

There is a volume difference by a few decibels but that isn't much. But they sound very different. Even the 600ohm one I bought from tongson plays at the same volume. The 250ohm one sounds very thin with bright highs, while the 600ohm sounds fleshed out with less fatiguing highs (mids are more fleshed out). So I know the phones aren't the exact same.

So I have two 600ohm DT880's and they both play at nearly the same volume as the 250ohm DT880 on my Zune, but when it is set at a volume above 10 you can hear that the 600ohm is a little quieter.
