lol eterna is designed for bassheads.

If its too much bass, theres silverbullets which are more mids centric and have a lighter bass thump compared to the eternas.

PL50 is a crappy iem imho.
everyone who auditioned them after hearing the Eterna and silver bullet, gave me a dirty look.

I'd prefer the pl30 anytime.
I would be inclined to agree, but I've never used EQ - not that i can remember
I don't see a reason to start using it now.

For me, i'd just play around with tips to find the sound i'm looking for.

failed to find custom tip , perhaps wait for jaben ss15 to open to buy some nice tip XD

I didn't touch my eterna for a whole week and in that period I only used the hippo shroom. Now I'm using back the eterna I understand what others said about their first impression: bass is kinda overwhelming.

But now I understands what it matters is to find the best "synergy" between the song-source-amp-IEM to get the best result. Songs are affected like IEMs too by means of different mics used, recording position, the mastering etc (even the monitoring speaker/headphones used will affect the sound of the songs). Some songs that sounds exceptional on the hippo shroom sounded lifeless on the eterna and vice versa.

I prefer vocals on eterna though, hippo shroom sounded a bit sharp and I never heard people's voice in real life like that. Eterna's vocal sounded more natural.

Glad I got both
