Get the Etymotic 4P. It has a beautiful clear action-packed sharp sound.

I wanna get this to get a different more developed sound than my J3 cause I like collecting different players. It looks like it would go with Vinyl club music with the sd cards (can these be 32G?). Would the sound fit? Or maybe I don't need it cause I have the J3. Is the sound markedly different?

Thank you for your help. I have fixed it.

The volume doesn't go past 32 on my J3 ever since I hooked it up with an amp. I've tried resetting, loading defaults but nothing happens. I want to get it to go back up to 40 again. Any suggestions?
