Hello! I've been doing way too much research and cannot decide on a $300 IEM. I'll be using it for metal (mostly black) as well as neoclassical/neofolk/post-industrial. So I guess I'm looking for: -Ability to express details (all of these genres are instrumentally layered) -Something "fun" sounding -Treble is important in black metal, but I do of course like my bass... not looking for anything necessarily V-shaped, though -Comfort and fit are very important. Don't care about look and wires. I've been reading about the Periodic Audio Beryllium, Massdrop Plus, Etymotic ER4XR, and Shure 535, but I don't know too much about audiology (I'm a video guy). I would be willing to spend a little more than $300 if there's something truly great that would fit my needs. The LZ A5 looks good, but it seems that it's buggy and has to be ordered from overseas. Thank you for any advice!
