HD 25-1 Circumaural Mod?

post #1 of 10
Thread Starter 

I have a pair of hd25s on the way and I've been reading heaps of threads about them because I'm so excited.

 

The two biggest problems with them seem to be that they lack sound stage and that their supra-aural design is uncomfortable.

 

I was wondering if a "MS1000" style mod would be possible with the hd25s? Could there be anyway to fit circumaural pads and possibly increase the ear's distance from the drivers? Even if this was possible would it ruin the sound? 

 

Here's an example:

HD 25-1  --> HD 25-1000

Anyone intrigued?

There isn't much you can do

 

I've tried to do the same idea for Grado, came up with nothing that worked

Increasing the distance from the ears and changing the pads (potentially changing the density will affect the sound; whether it's an improvement or detriment depends on your tastes. You can try something like the wood C-Pad adapter from Headphile, but personally the disadvantage there is the HD-25 is primarily a portable, so using wood won't in that department.

Whoa, C-Pads cost more than the headphones themselves, that's a bit too much for me. Can anyone think of a DIY solution? Are there any headphones with housings big enough to accommodate the cups of the HD25? Also how would it effect the sound? Bass/Mids/Highs > or <?

As a general rule, supra-aural headphones are designed to sound good with a very small volume of air between the driver and your ear.

 

Circumaural headphones need to sound good with a larger volume of air around the ear, which leads to very different designs.

 

This might not be that true for Grado, which are open, but that volume really matters for closed headphones.

 

Bottom line, if you are talking different enclosures, you should have just gotten a larger, more comfortable headphone to begin with.

I don't think there are C-pads for the HD25; what I was suggesting is to make something like it. Try some solid, round surface where you can stick some circumaural pads and the inner diameter can fit onto the HD25 driver housing. Wood's the easiest to cut but for moisture resistance, try plastic. Like find an old gym bag and use the hard plastic lining on the interior bottom, cut it accordingly, and use strong but removable adhesive to stick the pads and the driver housing. Try blutack and just trim out the excess when you squeeze it.

I bought some sound isolating circumaural hd25s.  They sound great, though the sound is not any tighter or more resolved.  They are far less quirky about how you position them now.
