I am currently listening to the JH16 with FreqPhase built-in. I am currently listening to "Simple Man" by Shinedown. The JH16, to my ears, is offering more of a 'textured' sound versus the original JH13 I have here. I will try to better explain what I mean by 'textured'. The sound has more realism or more 3D representation. However, I hear a huge difference in the low-end comparing the two IEMs with "Simple Man". The JH16 rumbles which makes this song difficult to listen to with both CIEM because they are offering such a different presentation. They are on opposite ends of the spectrum.
I am currently using an old 32-bit laptop with Jplay/Foobar as the player. I wish I still had a portable amp to use. I will add more later. Time to do some work
Note: The JH3A turns the JH16 into a different CIEM. The JH16 is awesome for having FUN with your music. The JH13 is more capable of representing all music genres and better sounding out of a DAP. However, the JH3A squeezes everything out of a CIEM in my opinion. Stay tuned for my thoughts on the JH3A with FreqPhase JH16.
