Thanks for the extensive list, I'm sure I will refer back to this when I take the plunge for a pair of customs in a couple of months.
I was hoping for an IEM recommendation from you guys, as I haven't heard too many IEMs. Long story short, I gave my brother my Sony xb-90ex (which I was using for the gym) because he loved their sound, and just thought to myself that I'd buy another pair for $90 online. Turns out they're quite hard to find and cost over $200 now.
If I'm going to be spending over $200, I'd like an IEM with detachable cables (preferably 2 pin). Could you guys recommend an IEM in the $150-$300 range with detachable 2 pin cable, a gym friendly housing, and that sounds like the Sony xb-90ex. I owned the Sony XBA-A3 for a bit, but the housings were too awkward, and I believe they used MMCX. Thanks!
