I got the m4 and m5 in my hands , I was quiet surprised to see it was in metal shells, I thought it be acrylic. I actually love it in its metallic shell, feels and looks extremely highly built and on a very high level of craftsmanship.
The m4/m5 are similar to 64a design, I will admit Fir is amazing. Its just a step a head on every little detail vs my trio. The shape of the shell is so precise it fits into my ear just like a custom! It literally dives into my ear actually, this is the deepest and comfortable fit I ever experienced with an universal!
As it goes for sound, I only got 1 hour so far and M5 cant go out of my ears hahaha, even the poor m4 cant touch m5. M5 is so natural so grandiose. For now all I can say is this is like wearing hd800s headphones in open back feel and also he1 as for treble feel, the voices are very very natural life like. I just am under big impression atm and really enjoying them alot.
I started to test solo and guitars and solo signers in small concerts. Really impressive how everything is perceived with good natural feel and music is so open and free of restriction, just flowing like I had no iems in my ears, very impressive
So to be continued folk
