I agree with Mesonto. All Borresens sound harsh, and unpleasant to my ears. They image very well, but sound is so sterile, so mechanic, I can not stand more than few minutes. First few minutes, that hyper detail and imaging is interesting but after few minutes you do not want to spend to much time with them.
Borresen X3 measurements
Borresen’s X3 measures pretty badly which contradicts a lot of the praise…
