The best IEM I have heard was the RE-262, and I have always wanted to buy RE-400, but they look so fragile. At the same time, CIEM is an unbeatable experience. I had reshelled by Sony XBA-3 and the CIEM fit makes a lot of difference. Now I tend to stick with cheap and effective type of IEMs. Signature Acoustics, Knowledge Zenith, Vsonic etc. Why not try a CIEM?
