Yamaha DTXpress/DTXplorer/DTXtreme

Hey guys,
Has anyone tried these phones before? Sennheiser HD 202.  Apparently 
they are this years model of the HD 200.
Just out of curiosity, can someone check the specs to see if it will 
be loud enough for my DTXPRESS 1 module.
Here are the specs.

ones_dj_05176?Open&row=2

Techn. Data 
Jack plug 3,5/6,3 mm stereo 
Nominal impedance 32 Ohm 
Weight w/o cable ca. 130 g 
Transducer principle dynamic, closed 
Ear coupling supraaural 
Cable length 3 m 
Frequency response (headphones) 18.....18000 Hz 
Sound pressure level (SPL) 115 dB(SPL) 
THD, total harmonic distortion <0,5 % 

Thanks for your help,
Mike

Mike,

Sorry. You seem to be getting me in the lottery these days. The 
impedance and and SPL are more propitious for volume than the 433s, 
and the sealed design bodes well for keeping out the stick noise. The 
only question is whether their sound will satisfy you, either because 
of their own compromises or because of the little Yamaha headphone 
amp's (in)ability to drive them cleanly. Here's the product review 
from the Headroom Company:

"In years past, finding a good sounding sealed headphone was very 
difficult. We now find ourselves in the midst of an abundance of 
them, including the Sennheiser HD 202. These headphones are solid 
performers in all areas, with an excellent tonal balance—neither too 
warm nor too bright. Though they do exhibit the typical (for 
inexpensive cans) "honkiness" in the mids, this flaw is quite modest, 
and easily tolerable considering the price. Like other sealed 
headphones in this price range, these cans are great for keeping the 
kids' video game music out of the way or for keeping the sleeping 
dormmates from waking up to your personal recording of a bar band 
doing "Cum On Feel The Noize."
The HD 202 use a sealed, almost-circumaural headphone design. They 
have small, circular, velour earpads that almost surround the ears, 
but are not quite large enough to prevent the flat part of the 
earpads from resting gently on the ears. The result is a set of 
headphones that have the light weight and small size of a supra-aural 
design, but have the secure fit and comfort of a circumaural model."

Unlike with studio cans, the construction does not seem to favor 
heavy use, and the cord might get in your way. Make sure that you can 
return them without penalty before you buy them.

Mike,

As I see it there were three issues for me when it came to buying
headphones: volume, ambient noise level and sound quality. 

The module generates the volume not the headphones.
The dtxpress1/2 module can only produce a certain level of output, even if
you set all the volume levels for each pad at 127 and the master volume
level at the highest level. By setting all the pad levels at the highest
settings, I could get a reasonable volume level through my Audio-technic
closed back headphones but I lost the ability to make a particular
drum/cymbal standout above the others. The only way to achieve that was to
lower the volume all the pads to 70 and tweak the other pads that I wanted
to stand out to 100+.  This meant that I would need something to increase
the volume level externally. My solution at the time was using a pre-amp
initially and then ultimately to purchase a mixer (Mackie DFX12).

I tried several headphones (borrowed from friends) and noted that the closed
back design was the only way to minimize the ambient stick sounds.

As far as sound quality, after spending many years, playing the music from
Uriah Heep, Deep Purple, etc.it is a moot point. I actually went to one of
the Deep Purples concerts back in the early seventies when I was in Germany.
We sat about 20 from center stage. The volume was so loud, that I remember
screaming at the top of my lungs about 1" from the ear of my buddy and he
couldn't hear a word I was saying. We had to wait until between songs to
talk. I had ringing in my ears for days after that. That was the days of the
120-130db concerts, louder is better theory. I pretty much have continuous
ring these days so that the "sound quality" issue is almost irrelavant for
me these days.

So basically, ambient noise levels and sound quality can be addressed by
quality headphones. But volume can really only be addressed through external
amplification.
