I find the single flanges to be the best tips. They offer identical sound to the bi-flanges and are slightly better than the foam tips but with isolation somewhere in between them. There's a reason why you get more than one kind of tip, not everybody has the same experience with each one. It could just be that you're not compatible with the single flanges, doesn't mean they are faulty or defective by design.
