I have been looking at these for a while now. And since i´m back on the shopping spree from some months off, im starting to fill up my IEM collection.
I have the XBA-1ip which i am not that impressed by to be honest. It feels "almost" like a good IEM but it falls short in clarity for me. The bass is tight and the articulation with voices and instruments is very good, bass is tight and fast. But the overall sound sound murky and held back in a way.
Since i stumbled upon these again on Amazon i kind of had to buy them to get the "want" out of my head. Enough said i picked them up today. I´m just a couple of hours in to the listening session so no full review for a while. The fit and build quality is way better then the xba-1ip, that´s the first thing that struck me. Second is the added clarity, they keep the tight and well articulate sound as the XBA-1 but feels a little less held back in the upper freq-range. Since they are straight out of the box i will let them burn over night. Placebo or not, i have always found that burn can do wonders ( for my brain/ears at least )
