Just received these today. I will say that I really like the shoe-lace cable. Microphonics while walking around are minimal, and that's without the shirt-clip and without wearing them over-ear. Minimal is, of course, relative. For reference, my only other pair of IEMs was Denon C700, and I was very sensitive to their microphonics.
I'm not sure if OP mentioned this, but I believe they include less tips now. I recieved three (black) single flange silicone pairs and one (clear) bi-flange pair. If I am not mistaken, the RE2 originally came with four pairs of bi-flange. What I am trying to figure out is the size of the clear bi-flange that came with my RE2. Originally, the clear bi-flanges were the large ones, right? So I'm wondering if they just bundled one large bi-flange or one medium bi-flange.
