It's interesting when people bring up bass with IEMs. It seems that most manufacturers (and users) like to see boosted bass, in order to make up for all the energy that your head/body absorb when listening to speakers or full-sized headphones. To my ears, this isn't accurate because it also messes things up tonally. Intuitively, it doesn't make sense that you can just boost bass in order to replicate that phenomena. That's why so many IEMs on the market are intolerable for me; they muddy up the bass for the sake of giving you a more "realistic" feeling of it. Maybe this is a discussion for another thread.

I think the Noble 4 did the bass pretty well. It was definitely boosted next to the ER4S, but well balanced and not excessive to my ears.

Perhaps. Note the plots so far have no compensation though. I made no attempt to compensate for excess of lack of perceived bass so far.

Would love to take a more critical listen and measure your ER4S OJ. Possible that by that time I will have a compensation curve ready and maybe can provide both pre and post compensation measurements.

I'm not saying they lack bass because of the graph. I heard then, I'm not bass head either, I think the HD800s and sr-009s have perfect bass, the 4s were definitely lacking bass and in particular any deep bass in comparison

Soup: For reference, which IEMs do you feel have ideal bass levels? In terms of quantity at least.

I'm not sure I've ever heard an iem with ideal bass response. I do like my JH-13 FPs but I know they aren't reference in the bass area. Maybe the Fitear MH334s? Still haven't had a chance to hear the UERMs

Have you managed to develop some kind of RECD curve yet? Just curious.

I have an idea of what to do using some full size headphones and the ear coupler, but haven't done it yet. Thanks for the paper link. Will read.

FWIW, I seem to recall reading in one of Sean Olive's papers that subjective tests indicate that people are more sensitive to too much bass in IEMs than regular sized headphones. Seems bassakwards to me...that's why I remember it. But if he said something I take note.

Shut... I'll do some comparos in that area after I get a compensation curve. Many of the dynamic IEMs, even the more "neutral", do sound a little bass heavy (with proper seal). That said, many of the BA's sound lean to me, including the Audeos which seemed pretty analytical. Only the uncomfortable as hell TF10s of the BA type IEMs I heard were a little bassy ... Well, the Noble 10s maybe, but didn't spend to much time w them.

We'll see.

OK. So I tried creating a RECD curve. Comp curve (what I would have to add to IEM measurements) looks a bit too wacky to me:



(dB in the y-axis, and Hz in the x-axis)

I will not currently apply it because I'm not convinced its correct, and because I have a feeling that different ear models might yield different results. I feel it's proly best to use FR results relative to other FR results from a similar rig and methodology (specially for IEMs).
