I recently got myself a pair of iSK Little Gems, so I thought I'd take a picture of the internals and upload it. The input capacitor and all other components are through hole, and the transistors appear to be 2N5401s. That zener is 9v1. The PCB is a bit cramped, so I'm not sure what mods could be done to it. It's worth noting IMO that you'll probably have to clean the back of the PCB because there was quite a bit of leftover flux.
The capsules have the slotted grilles like a lot of the Chinese ones, and they also have a layer of foam, so there may be another grille under the foam.
Another interesting thing is the contact pin in the body retracts quite a bit.
Again, I'm using my phone's camera, and it's not great in normal home lighting.
