Maybe keep scrapping the sticky adhesive to see if there are screws hidden in that frame around the driver. Thats the where the screws are hidden on all the ATH electrets. With a popsicle stick or some other soft wood poker you could push all that black tar like adhesive without scratching the...

Anyone pulled these apart to see how similar the carbon diaphram or integrated carbon is similar or different from the carbon nanotube driver? I know the HAS400 is 30mm vs the HAS500 & HAS770 at 40mm. I've had amazing luck modifying my 400s. I'd like to experiment with as many of the JVC series...

Just entered the club of electret ownership with an ATH-7 headphone and exciter set for $43US. I replaced the pads with cushy pleather ones from an XB300 clone. The bass quality did improve, but the headphones still struggle with any post 1990s synthetic sub-bass. I have them running through a...

This is some great advice thanks everyone. I will ditch the aluminum and try some listening sessions with silica packets. I need to get more for my camera lenses anyway. Its been a humid summer. I tried other fabrics but the bass just always sounded best with the leather/pleather materials...

Heat control/dissipation in closed t40v2 project.  I was wondering how much heat energy most orthodynamic drivers create. It seems like most of the heat would radiate from my ears and body getting trapped in the headphone pads. Tight sealed deep pleather pads are great for isolation bass...

Quote:   I forgot about this thread. It seems to only come up if you google search rather than internal search headfi. I posted in the main full size headphone forum but I should have went here instead.  I could't delete the old post so here are my mods:   I have beyerdynamic...

I have beyerdynamic DT250 headphones: 45mm drivers 250Ohms 100mW 97dB I sealed off the cup exhaust ports and covered the cups with acoustic foam to maximize isolation and tighten up the bass that was dark, overpowering and slow to release. After the changes they sounded bright and bass...

Looking for more tips/techniques to increase the passive noise reduction without changing the Fostex cups or sound signature of the drivers. I've already found all the mods I need for the sound I like. Now I just want to get them as close to noise isolating as my Pioneer Monitor 10.  ...

Thanks for the Tips! Quote: My ears take in bass better with the bigger round circumaural openings like those from sextets. The stock pads were too thin and on ear supra-aural for me. Probably fine for some ears but weren't as comfortable for me. Its not that I don't get the bass, I...

I'm not sure if I should have started another thread but everything seems to be here anyway.   I just got into the world of Fostex Orthodynamic Headphones after hearing the amazing modified ones at the last LA Headphone meetup. I purchased a Mickey Mouse round pad/cup t20v2 on Ebay which...

I am interested in a los angeles meet. thanks   ps: if the meet is close to LAX parking and you ride a motorcycle parking is always FREE for 2 wheels at LAX!   Just ride through the gates in and out you don't need a ticket or anything. You'll see the designated parking spots...

  Quote: I read that the HD600s warm highs make for good listening at low volumes like you mentioned. Going in that direction I tried an Ultrasone HFI2000 thinking the brilliant treble route might help for details and seperation at low volumes.   The Ultrasone was a good example...

I've been interested in using my unique looking Kenwood HS-5 housing for a project.   However, I can't figure out how to get to the drivers. Is anyone familiar with these? There aren't any screws anywhere and none of the brackets or cups screw or snap off. The pads have a twist off...

Yes I find that larger soundstages don't seem to blend stereo rock instrumentation as well at low volumes; like the DT150. Left vs right guitars sound too far apart and distant at your sides. Separation is good, but too much at low volumes becomes unnatural. Quote:  

I'm looking for something to fill the hole between the two extremes of my favorite headphones for low volume listening. I want a natural compression that will keep the volume level steady and low, but not allow soft sections to drop inaudible or loud blasts of sound to jump out and attack...
