Great idea for a thread
@Arysyn. So we are looking for flat to slightly frowning face frequency EQ? Is there a better name than frowny face?
Anyway, a acquaintance just ordered a new pair of headphones that has a sound description worth reading. Make sure to read down to the design brief. Haven't heard these. But these are my nomination for anti - V headphones.

A smooth V shape makes some sense, we don't perceive all frequencies equally independently of pressure level, so it seems louder than actually is. A flat response (not flat but with a frequency response as a flat frequency signal would produce in the eardrum) is probably the best compromise, but may not be the best option for low listening levels. If you like flat try the Etymotic ER4 SR. If you like a superb midrange, flat and detailed, and don't mind a relatively week bass, the DT-48 (discontinued) was very good.
I want to have this thread be open to both dd driver and ba driver iems. Personally though, I find ba drivers to be an easy choice for those wanting non-v shape sound, especially in comparison with dd driver iems. It is very difficult to find a non -v shape dd driver iem. Flare Audio being one of the rarity companies focusing on a neutral to mid-forward tuning. If I were more fond of ba drivers, I could easily find an iem to suit my wants in an iem. Etymotic being one of them. While I never have heard any of their products, I've read some great things about Empire Ears, and they even have a fairly affordable, under $1,000 vocal-focused iem. I strongly support the decision EE chose to make it.
The EVR :

While at some point I may decide to try the EVR, there is one problem I have with ba driver iems I've noticed in all I have heard so far, from the unique "moving armature" driver iems, the Grado GR8 and GR10, and the Ortofon EQ8, all three I still own. Also, the Etymotic ER4SR, and the older ER4 models, of which I no longer have. I haven't heard any of the multi-ba armature iems yet, so I'll admit its possible not to have the same problems I noticed in the other ba driver iems I've heard. The issue being one where at least to my hearing, the ba driver iems I have heard sound as though half of the vocal and instrumental dynamism/richness is missing, like its been made artificial sounding.
I'm figuring this might be a bass-related issue. My views on bass are a bit complex. I despise bass for what it does to music in forms of heavy thumpiness to sound, that somewhat headache-inducing boom that is like the bass version of treble harshness many people complain about with treble. I understand that, especially after hearing it for the first time from the FlaresPro, an overall excellent iem that has only one flaw in the sound that presents itself in certain songs that have cymbals and tambourines.
Its my opinion the problem with the FlaresPro treble is in the upper treble regions being increased and extended ib that range. For whatever reason, I don't hear the same treble harshness from lower treble-focused iems, such as the HiFiMan RE800 some have complained about. I'm still in the process of learning about the elements of bass, trying to figure out the "good bass" from the "bad bass". Again, while I don't like the "boom" of bass, there still needs to be some warmth from it, in order to maintain the proper emotionality of the music. If those here with more knowledge of bass than I could better explain this, please do.
From my figures in seeing various fr graphs, I pay attention to three critical areas to my preference. I've learned to watch out for the lines not to exceed neutrality anywhere in the bass. I'm fine with neutral level or below in bass, but only when looking for dd driver iems. I'm really not sure what to be looking for in ba driver iems that may help the problem I hear in them, if there is anything the bass levels can do. That is something I do not know, but would love to learn more about. So far, I'm just going by my experience and of course what I do know, which definitely favors dd driver iems.
Sadly though, there aren't many dd driver iems that fit well with my preference. Despite plenty having neutral bass, it seems that from there, audio companies just love to put that recess in the mids. I've seen dozens, maybe even hundreds by this point, fr graphs for dd driver iems where there is some level of mid and vocal recess, even where bass and treble are not much increased. Those would be mild V-Shape signatures, but to me, even those are not so good to listen to. I can easily hear the recess in vocals, and it is very frustrating to me why this is so popular when the majority of music still is in the mids. Instrumental music may be fine in V-Shape iems, but having to swap iems when going from those songs to songs featuring vocals, is frustrating.
So, besides my looking for neutrality in bass and at least that in the mids when viewing fr graphs, I also look at the treble. I'm fine with neutral treble, even some light recess - which I find especially important in upper treble to avoid harshness, but preferentially I'd like for an enhanced lower treble, so long as harshness is avoided. Still, I've yet to hear harshness in lower treble. Its only in the upper treble where it is a problem for me. I'm suppose to receive the Flares Gold by Flare Audio on Monday, and am planning on making a day of it with careful, closely precise listening so I can write a detailed review of it on Monday. Of course, I'm hoping for the best from it, especially due to the rarity of its sound signature among dd driver iems.
Anyways, I'm also hoping for this thread to become a resource for all products not with a V-Shape sound, whether they are dd driver-based, ba driver-based, iems and over-the-ear headphones. While my preference is iems, particularly dd driver iems, I really want the focus here to be the sound signatures not V-Shaped. It can be either mid-centric or mid-forward. Heck, even the odd bass-prominant or treble-dominant ones that don't carry a V-Shape. The main interest here is to focus on making the mids not be viewed less between the two sides.
Even if one of them be a priority in the product, having both is really unnatural, at least in my opinion. Having a product saying "Bass-focused" "Treble-focused" is better than saying all sound is more important than the mids, where clearly the mids are being ignored for the sake of something that really is not specific. Again, my opinion here, but putting an emphasis on both the bass and treble just isn't sensible to me. They are both at opposite ends of the sound spectrum. Fine if you want to focus specifically on one of them for a certain sound target, but not both where it takes a very heavy toll on what is being left out, the mids. It really messes up the sound that way.
I'm going to have a new fr graph made for me very soon, that will show my updated sound signature preference I have since my experience with the FlaresPro and its upper treble harshness. I need to have the upper treble reduced from what I thought was a good level in my previous fr graph. I'll post the new one as soon as its made.
