Beyerdynamic DT150 250ohm
« on: April 24, 2014, 01:36:40 PM »

One guy discovered them, and I recently had a chance to borrow it.
And you know, they are damn awesome. I dont like 770-880-990 modern line at all, but this thing is totally different.
Very clear, fast and detailed. Possibly one of the best Beyer's out there. I choose this over T1 any day.
Bass can be overwhelming sometimes, but it is so clear, that it does not affect middle at all. This does not sound like a typical closed can. While soundstage in not wide, its not feel restraint also.
Overall I can describe it as "in you face" energetic sound, in a good way.

note: bass distortion is not accurate, it is caused by environment conditions.



Also, earcups are elongated, and so at certain fit can lose seal. I tried to emulate this on measurement stand and got this:

Will have to give this a try, my friend sold his and regretted it a long while back. They are pretty darn huge headphones though.

Wow. That sounds like one rich/thick sounding headphone... while maintaining air and detail. The CSD looks phenomenal.

Rabbit a.k.a. Ian loves this headphone. It was popular in broadcasting.

That's because of the used time scale of the CSD  ;)
You don't see the decay of the actual headphone, all you see is the decay of the software filtering.
Still for the lows it isn't that bad. You can still see some resonances of the headphone peeping through the 'filter wall' on the bottom of the plot around 70Hz and 200Hz, the rest is the decay of the software filter.
Also from 500Hz up the dynamic range is just 24dB.
I recommend to set the CSD so the bottom frequency is 500Hz and the total time scale is around 6ms.
Then you can see what the headphone does.

The headphone is used as a monitor and according to Rabbit (long time owner) it isn't a very 'hifi-ish' headphone and needs to be EQ'ed to sound good for listening to music.
Very good for monitoring individual instruments in a studio.

A sturdy 'workhorse' that can be thrown, sat-on, abused, yanked on etc.

Im not sure where in Arta I can set up this options, but Its possibly close enough -

Today results are a bit worse than yesterday, somehow. Meh.
I can increase bottom value, but want to keep in close to Purrin's set-up. Its still clear from 3kHz at -50db.

I haven't heard these, but I concur that the DT250-250 are really awesome. I have some 250-250 drivers put into closed wood shells and I am running them with stock velour pads. They do sound great means fast, balanced and acceptably resolving, in a way similar to my HD600s, yet the bass is more visceral and tighter, the mids not as forward. It is only the highs that the HD600s do better. Anyway, I think these drivers are gorgeous.
