Bass performance in IEM's

[Ambient384]

After trying Harman bass on my ER3SE I'm starting to question the folk who hype IEM's with 11.5mm DD's or 2x 7mm BA woofers. Using 1990's EQ profiles(low shelf) I set It to 10db like It says but I set at 105Hz instead of 155Hz, It legit sounds like my past IEM's bass quantity wise but with much better decay/detail.

With the EQ my ER3SE sounds just like a IEM with a 10mm+ driver?.
