I bought a set of e3's a month or so ago and I think I have had time to get a proper fit. I cant hear much with the foamies and music playing. Yet the sound quality is really lacking a full vibrant sound. I have yet to say wow and I have tried listening to cds with the same results so I know it isnt a matter of encoding. I listen to all sorts of music and expect the e3s to shine mostly on instrument heavy stuff. But I hear the same detail and aural color as with the stock apple buds. Is there a way I Can try to see if it is my particular set or some other factor. Thanks.
