I currently own a set of Shure SE535 Ltd earbuds. I am quite happy with the sound, though I never tried higher quality ones to compare. [SHORT VERSION] Will adding custom molds to my SE535s improve sound and comfort far enough to justify the money spent? [LONG STORY] The only thing that gets on my nerves is that I need to use the foam bits to wear them - If I use the rubber cones, I don't get enough bass. So it means that I need to squeeze the foam, insert the earbuds and wait for a bit for them to seal me off. During band practice that means that when we stop to discuss a part, I need to take them out to be able to hear what people say and when we get back to play, I have to re-insert them, including the wait. My local shop for hearing aids where I had my hearing protection molded offers custom molds for any IEM earbuds. They will cost me about $150 and the sales guy told me that they will be able to adapt the molds for the sound I desire, so if I wanted a better bass response, they could do that. From my protection molds I know that these just pop into your ears and seal off instantly, which is very convenient. If molds were improving the sound of my Shures and make using them more convenient, I think that's 150 bucks well spent. If there were issues with the connection of the Shures and the molds, the sound, the overall comfort or something I can't foresee at the moment, I'd rather leave it as is and maybe get a molded set in the future. Has anyone here used the 535s and added the molded pieces and can share the experiences made?
