If you are looking for a more neutral, less bassy sound signature, supposedly the Maximo iMetal 590 are good for $50. I have tried a ton of IEM's in the sub-$100 range and continue to go back to the S4 for their unrivaled comfort, great isolation, and arguably great sound quality. I say arguably because on Head-Fi, many critics of the S4 have their own personal preferences and have certain expectations of IEM's, and when a certain IEM does not reach their expectations or does not fit their criteria for excellence, they become "overrated." It is easy to forget just how subjective hearing actually is. One person's "overrated" IEM's can easily be another's favorite. Objectively, the S4 are not trash, they simply have a particular sound signature that some will like, others will not. Why is this so hard to understand for some people?
