So, I have a very specific question. For those of you who use (what I would call) "high end" IEM buds, and have used both molded and universal..... Was there a tremendous difference? Was one much better than the other? I am specifically comparing the 64 Audio A8 vs U8. I can actually see advantages to both kinds....but primarily universal fit. (Price is not a factor for this discussion.) 1) Resale - I can see resale being a possibility if I wind up not needing or liking them with universal fit. 2) Flexibility - I can try different materials of tips until I find exactly what I like. 3) Cleanliness- After a few shows, just chunk those flexible tips and put on new ones. 4) Better seal - If the ear bud tip is expanding to fit your ear canal every time, it must be sealing up nice and isolating well. I guess what I am trying to say is I need to be talked into molded buds before buying them. Again, price is not a factor.
