id go with the er-6, which doesn't sound worse. the 6i is more efficient (you will have to turn the volume up a little bit more with the 6) and has stronger bass, but the 6 is more accurate.
I'm planning on getting one of these with the iAudio X5. Considering that the ER-6i is "better" than the ER-6, it is white, so its not going to match, but does the sound quality make up for it? Thx
