I'm getting a second listen to the Primo 8; this time for a couple of weeks, so there's ample time. My thoughts are similar to what they were the first time around --- sound-wise, they're really quite good --- about as good as it gets for its form factor (small and single output port, not a CIEM-derived design), and definitely at the top of the heap for the <$500 category of universal IEMs.
I do believe I'm enjoying them a lot more this time around --- I'm not busy picking out its technical shortcomings within a 12 hour span!
Not to be a Negative Nancy, but getting the criticism out of the way first: the ear guides really are a bit too stiff. They feel nice against the skin, actually, but they take forever to adjust, and make the cable look thin comparatively. It's not a huge problem, but worth mentioning nonetheless.
