I picked up a pair of AKG 702's which have a sonarworks profile on a deal. Sound great via sonarworks and they are comfortable.

The MPC headphones must have been discontinued.  They  are no longer available at AMS or zzounds.  Good news is that I bought them when they were available, and I agree with cclarry that they were a quality steal at the sales' asking price.

Remember also.... YOU can SEND them your particular headphones and they will analyze the, and create a custom profile for you
 

OK, so the DT 990 Pro 250Ohm headphones came in today. Wow, they really hype the high end - HOWEVER, with Sonarworks they are golden!!! I could mix with these. Also, listening to some Pink Floyd using Sonarworks for correction is pretty damn cool - you can really hear the separation of each instrument, and the reverbs involved. Personally, I like these much better than the 770s...
 
I'm now good to go - thanks to all for the info.

+1  for the Rane HC 6 I am using that as well...Got mine off ebay from a defunct studio for less that $100! 

 

James, how about posting the correction curve for the DT990's? I'm curious to see what frequencies are hyped, according to Sonarworks.
 
Here's what head-fi.org shows, a significant peak at ~8.5KHz. Actually, I'd describe it as a broad upper-midrange dip, but the graph uses the usual 1KHz reference.
 
 
BTW, all you have to do is browse a few headphone frequency response graphs to dispel the notion that any headphones are "flat".
 
 

Wow that curve you have is nothing like I experienced. The curve provided by Sonarworks seems much more accurate. Certainly the correction sounds pretty flat to me.
 
 

Wow, indeed. That shows a nearly 12dB spike at 9.5 KHz. Yeh, if that's accurate then I'd definitely say it qualifies as "hyped".
 
The differences between the two measurements can be chalked up to variances between tested headphones and smoothing. Smoothing refers to the number of FFT bins, or width of frequency bands reported. A graph with no smoothing is almost useless because it shows too much detail, much of it irrelevant. At the other extreme, too much smoothing hides imperfections, a common practice among marketers to make their products look better than they really are.
 
Just one of the reasons frequency-response charts are to be taken with a sodium chloride crystal, and best used to reveal general observations rather than as the sole determiner of quality.

I agree with you Bit - and I appreciate you posting that graph and asking me to do so - very interesting stuff. I really like these headphones so far - especially compared to the DT770. 
 
Are you a believer in breaking them in? Should I run audio through them for hours like I did with my Adams and Auratone?
 
PS: If you really enjoy the sound of hi hats, then the DT990s without correction will make you happy! :)

No, I do not believe in headphone/speaker break-in.
 
There is no technical reason why it would ever be necessary, at least not with any quality speakers. There are some reasonable theories that say a speaker becomes more pliant after being exercised, but the time needed for that is about 10 seconds. Quality speakers will get that at the factory. 
 
I do, however, strongly believe that we subjectively grow to like the sound of headphones or speakers the more we listen to them. That could be the origin of this persistent myth.
