Haven't visited this forum in over a year (my wallet thanks me). Last time I was looking for some good cans, this time a replacement for my 4 year old Sure E4s that just broke. I have been reading for the past two days straight about all types of IEMs and I think the FX500 are the ones for me. Other options in this price range that I am looking at are the RE0 and Klipsch S4. Can anybody make a comparison? It seems like the consensus is that the Victors are better than the RE0s, especially when concerning bass. Not much about the Klipsch S4 on here, just wondering because of the glowing review they got on CNET and some other sites sparked my interest. Just looking for an all around good IEM, and I do like my bass (since I listen to mostly Hip-Hop and R&B). Another important thing is comfort, since I always listen to music while I study and sometimes that can be hours on end. I get the sense that isolation isn't that great, am I correct on this assumption? Even thought I would like better isolation, by all the glowing reviews it seems like the pros more that outweigh the cons. Thinking about placing an order, just want some final opinions from the experts before I do. Any suggestions or advice would be greatly appreciated, thanks!
