Tascam TH-02 - Headphones waiting to be discovered??? (now Appreciation Thread) - Page 6

post #76 of 170

Yeah, the difference is in the cup construction. iirc, in the HD555/595 all Sennheiser changed was adding a piece of rubber. But the change in the FR is over an octave wide and not peakish.

 

Still, I'm not saying it's impossible to tame the 10k peak a bit with a mod.

Aargh, headroom measurements... Those data do not support modders' argument. First, that difference is well within a driver's sample-to-sample variability as well as within measurement setting's variability (e.g., slight change in their position on the dummy head).  


Second, if you change headphones' ear cup structure, of course, you will see some, most likely, small effect on their FR due to the change in the reflection profile. But this is very difficult to predict---a modder without measurement will simply make a haphazard decision. And more importantly, a slight change in the reflection pattern is unlikely to cause a difference adequate to remedy a large FR anomaly due to diaphragm resonances (like the Tascam's).

Any specifics/pictures about how the rubber was added to HD595?  Only saw this: http://www.head-fi.org/t/602751/sen-hd-595-600-or-beyer-770-990-pro-need-advice.

Another week, another deal rolling in for the Tascam TH-02. If you don't mind white, you can find it for a good deal on eBay. It is now available for $20.75 from musicsupplydirect, an authorized reseller. It may fluctuate later after the time of this post. I was able to get it for $19.09.

Stripped these drivers of their plastic and gave them some wood. Overall, these sound very balanced and nice. Of course they are no resolution monsters, but good, flat bass and balanced sound is hard to find. Especially at a price like this.

 

Drivers: 50mm


Wood baffle, driver glued on

 

 

Cup: Black and white ebony. Connector: mini xlr

 

 

Frame

 

Complete with Brainwavz HM5 pads

Nice work Stratocaster

How much better does it sound vs. the original?  Does the 10KHz peak get better?

post #86 of 170
The peak does get better if you apply the infamous toilet paper mod, just use a sheet between the pads and enclosure and it will be tamed ~5 dB according to some pirate's analysis.

I dynamited the cover and put some TP in-between the ear pad and speaker.  I used a sock and cut it up to place around the speaker blocking the plastic.  Just an O shape.  Sounds really awesome now.  Bass still hits strong and no more treble spike.  That which I heard.

post #88 of 170

The TP mod works really well. That fixed up a lot of the treble issues for me.

 

I also suggest filling out the headphone pads with TP -- it fixed all seal issues that I was encountering.

Pictures?  Thanks.
