The consensus among MD owners on hfi seems to be that the 3.1 / 3.2 revisions boosted the bass so it is much more in balance with the midrange now. I guess it makes sense then that the bass in the OP measurements of the 3.0 seem too little in relation to the midrange "hump".

Deriving what changed from this FR comparison to the 3.0 measurements in OP, yeah the big effect would be that the midrange hump is significantly lowered.

Yeah, that's what I was thinking. I'd have to guess the latest revision would be more to my tastes, so I'll probably get mine retuned. I've only invested maybe $275 into my MD total (refurb unit), so an extra $30 isn't a big deal for me. I can see why others would be upset and/or annoyed.

I can empathize with these MD owners; I was heavily enrolled in the dang HE400 driver failure and later driver sibilance debacle over the majority of last year.

Follow up HD measurements as promised - some months later.
  • L channel looks about the same as before
  • R channel has more 3rd order this time around. Weird. I took the headphone off the rig and re-measured. Two times. Same results. Will check again with another reference to make sure the rig is OK. This is odd. Wondering if something shook loose inside.
This pair's been a bitch to measure.

Interesting. Looks like D2 and D3 are a bit high, but not horrendously so. I would really like to know how the stock T50RP and Paradox compare! I have no idea if the 3.2 MD revision improved distortion or not.

Sorry they've been such a pain to measure, but I do appreciate you taking the time to do it! :)

Let me dig up a stock T50RP. The T50RP is going to have HD on a slightly higher side, especially toward the lower regions. This is because of the small size of the driver.

T50RP stock HD for comparison.


Not too much different from the MadDog's as I expected. It would seem that HD (and FR in the highs) are not very consistent with the T50RPs. This is something a few of us have known or suspected for a while.

I hope he finds a way to smoothly bump the highs and then filter out the sibilant 8-10k region. A bit of extra controlled venting would do the trick, it tends to do that, the applying a specific filter to drop the sibilant part.

As it is, it kinda looks like my pair of Paradox, assuming my eq doesn't lie, which it shouldn't. I wonder how the midbass is, Paradox have a slight "perseverance" in the bass.

Ahoy, and thanks for running the measurements, twice!  I've been enjoying reading the thread.

Purrin, I suspect you were correct about why your first measurement was bass light... In shipping the pads normally deform.  If you measure right out of the box you almost certainly won't get a decent seal.  If the phones haven't been on a stand it's a good idea to wear them to warm the pads before testing; the foam will shape to fit your head (or fixture) when warm. 

The 3.2 version was indeed designed to smooth out the 500-2K region, it's definitely more linear there.  It's also the last revision I can foresee, we're really happy with it and I have no plans to change it further (nor will we change the ear pads).  3.2 is what the recent reviews and comments in many of the audio pubs has been based on. 

Purrin's graphs look like it was a 3.0, is probably pretty close to what I'd expect. 3.2 should look smoother in the mids and the bass/mid and mid/high transitions.

Hey, Dan. I must have missed something in the thread from the other site. It seems to be locked now and I have no idea what happened. It's a shame that the thread has been shut down for now. Also, thank you for the recent 3.2 upgrade. My pair was one of the two that mechgamer sent in. I like the change in sound and I'm enjoying them a little bit more than I did before sending them back.

It was a bit of a "huh?' moment that the thread was locked, but so it goes...  Anyhow, a new thread has sprung up, though, so all's well that ends well... 

Glad you're enjoying them...

Thanks for all the measurements, purrin! The HD of both the MD and stock T50RP are particularly interesting.

Dan, these are definitely the 3.0 revision as I mentioned above. Now that I'm settled in at my new location, I'll probably send you my MDs for tuning once I get them back.  :)p6
