ISN H50 is a bit underappreciated. Another fine set from ISN. Excellent review as always.

Thank-you.

True GEM.....

So in terms of bass:
EST50>H40>H50
Technical:
EST50>H50>H40
Soundstage:
EST50>H50?

No, forgive my new-toy-itis but H50 on all fronts? That’s how I hear them? I’m using FR to also handle a better way in technicalities, hope you understand? Soundstage is just different, maybe 50=50 H50/EST50?

The ISN H50 is truly on another level, than most IEMs. At least how I hear them to be? They lose the darkness of the EST50, though some may love that aspect? While the EST50 is a more refined in the top, the BAs of the H50 have more bite, thus balancing the DD better, to me. Part of the H50 allure is a love affair with the DD, as it’s deep, fast, separated and textured.

I seriously can’t get over how good the H50 is? The dynamic contrasts it holds, in combination with the staging! I see it as a final purchase for many, I really do.

I own about 30 iems and can honestly say this one of my very favorites, if not THE very favorite-------the fit is perfect for me--which is rare and I just LOVE the sound quality. I really do find myself reaching for these when I want to chill with some nice classical or jazz and want the "full" in ear monitor experience------everything in this hobby is your personal experience with the product and this one---it just works for me-------I have the 40 and the 10 also--
Would like to get the EST at some point but I really do have to say the 50 is my go to IEM----
