And if you are buying the re600s, just ignore the stock tips and get some nice ones elsewhere if you do not have narrow ear cannels, the tips are the same as re400's and poor in seal for me.
I agree with you that the tips included with the RE-600 will not provide a proper seal for many users. I have suggested to Fang that he make up a tip assortment of various sizes that will work on both the RE-400 and 600 and offer it as an option for those who need tip sizes other than those included. I also agree with you that running them balanced makes a marked improvement in their performance.
I had to scrounge around through my stash of tips from long-departed IEM's and finally found some that fit the 600 and my ears really well, but due to the wide neck used on both the 400 and 600, many tips such as those used for Etys, Westones, etc. will not fit. Without a really good fit, it will be impossible to fully appreciate what the 600 is capable of delivering. Instead, there will be little bass and piercing highs.
As is the case with many dynamic driver phones, the RE-600 does take quite a few hours of use before reaching their full potential. I have not noticed much change after I passed about 50 hours of use.Edited by HiFlight - 6/27/13 at 7:13pm
