Is there any different in sound signature and sound quality between DT880/600 ohm Pro vs Premium?

Both use the same drivers, but the Pro is normally only available in 250 Ω version, and it also has a higher clamping force, which does change the sound somewhat (you can bend the headband to reduce the clamp, though).

There's nothing different in SS between the DT880/600 Ω Pro and the DT880/600 Ω Premium to my own noob ear's, but i picked the DT880/600 Ω Pro for some reason biggrin.gif

what actually makes the 600 ohm version harder to drive, is the fact it will be voltage limited, personally I think the 10v swing from the +/-7v supply is pretty optimistic.

 

I found this thread pretty hard work, it hurt my head. the OP would simply move his rather vaguely positioned goal posts to account for any result he couldnt explain and call sampling error or insufficient information, despite calling on a total of 2 measurements made by a 3rd party through most of it. He also seems to somehow disregard acceleration when talking about speed of transducers.

 

the fact that we are talking about a headphone + amp system here at all times as used by all people seemed to be completely lost on him. differences in reactive loads, physical construction and/or damping of some headphones also seemed to not be part of the considerations when claiming headphones are not effected by damping factor, forget the very low Z type with crossovers, which are profoundly effected. not AS effected i'll accept.

 

One could claim that all 'properly designed' headphone motor systems and frames should be reasonably immune to mechanical resonances caused by sudden acceleration, but as with speakers not all headphones are created equal and neither are the amps that are used to drive them. there is still the electromechanical side too.

 

the relationship between these factors and preferred sound quality is not clean cut and attempts to make it so are humorous/clumsy

 

the model is completely lacking complexity, forget humanity. very 'neat' kinda like adding too much smoothing to a waterfall or speaker directivity plot

 

he also admits at one point to pretty much trolling, by deliberately using more extreme language than was strictly appropriate. This is including the title, apparently chosen to elicit his preferred flavor of (combative) discourse.

 

i'll admit, strictly sticking to the subject 250ohm vs 600 ohm should not present all that much difference when fed by a pure voltage source; all things being equal, not as much as sometimes claimed around here. If only it stuck to that rather than spraying all around it with many generalized statements with little or no backup

 

all very scientific…

Hi zeinharis, where did you buy the DT880/600 Ohm?
I could not find it on amazon.com. I also checked beyerdynamic.com, DT880/600 Ohm only comes with Premium and not Pro.

i bought it from jaben indonesia, here is some picture of it

 

 

 

 

 

sorry for the lousy pic biggrin.gif

The 600 ohm vs 250 ohm vs 32 ohm headphones may sound quite different on certain amplifiers.  For example, the Bottlehead Crack -  a highly-regarded OTL tube amplifier- would probably not be able to drive the 32 ohm version very well.  The 600 ohm version would likely be the most compatible with the Crack, and I suspect the 600 ohm version would offer better sound than the 250 ohm version on the Crack as well.

 

The premise made in the beginning of this thread-  that sound differences in the various DT880 are "BS" because there should be no difference in sound when driven by a zero-ohm source impedance is obviously flawed because many amps used by Head-Fiers are **NOT** zero-ohm sources.

 

Just sayin'......
