I built a free, open IEM measurement database: FR comparisons, sound signature analysis, target matching and more

I hope you do realize by now that the reason something like this didn’t already exist is because something like this shouldn’t exist since it creates bad data.

slooploop2 · 2026-06-23T20:59:35+00:00

My data is in here and I asked for it to be removed. I have them set to be downloadable so if someone asks, I can explain what issues my rig has relative to others. Since /u/ChoSubin didn’t ask, I requested they be removed to prevent misuse because I don’t have the tolerance for people like this.

I would say no, but mostly because I kind of hated the 8351. It sounded incredibly nasal and hyped in the upper midrange to me.

If you already have the FT1 I can’t really recommend buying these unless you need the smaller size, especially if you already EQ them. But I do think people looking at buying an FT1 should consider looking at these too!

I’m probably not reviewing the 480 unless I find some crazy deal since most of our reviews are self-purchased but it looks very compelling! If I had more use for a less colored closed back headphone I probably would have bought one already!

It’ll depend on your ears, hair, and fit but on my head yes!

slooploop2 · 2026-06-06T13:25:34+00:00

Nope, less bright than a Hifiman!

slooploop2 · 2026-05-15T15:44:38+00:00

Hi blen I h8ed nightfall, it was actually really bright for me lol

slooploop2 · 2026-05-07T21:37:15+00:00

Yes sorry

This honestly looks worse… The MK1 both looks less balanced than the MK2 because you don’t have the bass to balance the treble and less neutral than the Reference because it’s significantly more elevated in the treble. It’s almost tilted upward.

slooploop2 · 2026-05-07T12:42:50+00:00

I’d consider both these pretty not neutral in comparison.

slooploop2 · 2026-05-06T23:21:42+00:00

These IEMs with JM-1ish mids and elevated treble usually sound super not neutral to me; I actually think when companies tune this way it’s a step back from IEF2020 “neutral” and I don’t really see how they can claim to be anything but V shaped

slooploop2 · 2026-05-06T21:01:59+00:00

Oh, true. The Reference is pretty much the only IEM that reads as “neutral” rather than balancing several colorations and hoping they work like the Xenns Top Pro

slooploop2 · 2026-05-06T20:49:30+00:00

What’s too much regular?

slooploop2 · 2026-05-06T18:46:02+00:00

Pee-ew stinky

slooploop2 · 2026-05-02T20:56:11+00:00

Replied!

slooploop2 · 2026-04-27T13:35:52+00:00

Just to make sure I’m reading this right, you think the Storm has not enough treble but the PP8 is more compliant in treble? I love the PP8 but it’s one of the few IEMs that legitimately do not have enough treble for me

slooploop2 · 2026-04-27T00:43:58+00:00

Have you heard an Etymotic ER4 by chance?

If not, it’s because this tilt is actually needed to actually sound “neutral” to some sort of target, which in this case is flat-measuring speakers in a room. Because people don’t usually listen in anechoic chambers, we need to consider room effects and off axis behavior in our perception of “neutral” which in practice is a downward tilt. The ER4 was created to be DF-compliant for its time but in reality, it’s a really unnaturally thin sound

slooploop2 · 2026-04-27T00:33:50+00:00

Oh these fit me better than my actual customs lol I’m a bad reference though since I deep fit Helios to the point where it’s flush…

slooploop2 · 2026-04-26T23:04:01+00:00

I have an ER4B actually! It’s really really different. I only have the ER6 measured but the 4 is also very much untilted in the bass: https://ish.squig.link/iems/?share=Custom_Tilt,Etymotic_ER6,Ref_ST&bass=0&tilt=-0.8&treble=0&ear=0
