I love my Sony XBA-4's and have been using them for at least 6 months now. The soundstage suits my needs perfectly I just wish they would isolate a little but more (albeit they isolate exceptionally) and say in my ear better during workouts. As I was looking for a cheap solution, I came across the Decibullz Custom Earphone Mold: http://www.decibullz.com/shop/custom-earphone-molds/custom-earphone-molds/.
Does anybody 1) know how those molds preform fit and isolation wise of 2) know of similar products that may be better or worth looking into?
Thanks a lot guys,
