I have done several mods with large silicon tips. Many of them are posted before.
I have stuffed the large sillicon with
- Comply foam core
- Blue-tack
- Shure olive core
I have modded double flange with half cut Comply foam core. It gives me wonderful isolation on par with TF10. Very tight bass and more refined highs.
Out of the mods of silicon tips, Blue-tack stuffing is most uncomfortable due to hardness. Best SQ and comfort is achieved with shure olive core.
My next exercise would be to mod double flange with half-cut Shure olive core as I did with comply core.
I will post the comparison of sound quality, comfort and SQ later, after I listen more.
Opinions are welcome!
