Ok, I've just read through 6 or 7 pages, trying to catch up on posts in this thread before I got to your post. I'm going to respond because you've ordered some awesome buds with good stock tuning (rw9 and x6), and you're also considering higher tier buds, like the EM5 (which I own and have listened to extensively (since release) after burning them in for a full 200 hours, per
@ClieOS recommendation.)
I'm going to weigh in here with my opinion regarding EQ and also try to bring some clarity as to what my approach is with earbuds.
I realize historically "audiophiles" disdain EQ'ing their audio equipment, especially at the termination of their audio chain. To
@RikudouGoku's point, there are a number of things "audiophiles" utilize that are fundamentally "eq'ing" their sound -- from bass boost, to installing acoustic foam in their listening rooms, to spending tons of money on cables and tube amps. All of these things add coloration to the sound in a manner that is specific to the "audiophile's" listening tastes. They are equalizing the sound to an expectation in their mind. That said, there are the few "purists," like
@Alex.Grimm, do whatever it takes to maintain a level of purity through out their entire chain. This is hard to do and requires a lot of money to pull off well. I was this sort of "purist" years ago but gave up quickly since the amount of money it would take to match my ears with the expectations of playing in symphony orchestras for 10+ years would have required around $150k in equipment and retrofitting my room.
So let's be clear, most "audiophiles" do not have a problem with the fundamental concept of EQ -- they have issues with software-based EQ.
And I get it, to the mind of the "purist" software alterations to sound is more troubling than hardware influences to sound. You'll never hear me argue that software eq is the better approach, even though it is. j/k (I couldn't resist adding a bit of levity to this topic)
I'm a strong proponent for software EQ. A good number of audiophiles will never accept that and I'm ok with that. I likely won't ever convince them to see otherwise and that doesn't bother me. I'm more focused on trying to encourage new fans of earbuds to hear the possibility of jaw-dropping sound quality because of EQ to really affordable buds. By the way,
@furyossa is not the software EQ freak that I am -- he's a bit of both worlds and has one foot in the hardware side of things and another foot in the software "world."
There are users here who will never accept software EQ. I think this also has to do with their typical daily source usage. In my case, all my listening is done on the following devices: Pixel 4a 5g, Pixel 4XL (likely will be trading in for a Samsung S21 via the t-mobile $800 credit deal!), Note 10, Sony nw-a105, windows laptop, windows desktop, and older MacBook pro.
Why I am a big proponent of EQ'ing earbuds:
1. With my compensation files, it's easy to maintain consistency across various platforms and sources. It is also restrictive, for many users, sadly. (ie. iPhone users.)
2. Compensation files allow for quick, easy experimentation with various target curves. Click one file, click another, etc.
3. The improvement can be dramatic, especially with some earbud drivers. ie. datura pro.
Last words....
EQ'ing can be a pretty daunting task in and of itself. If I didn't have measuring equipment, I'd be lost completely. There are so many synergies and unpredictable elements as to how changes in one part of the FR affects others. A big motivation for my work is two-fold:
- Trying to understand if there can be a rough target that improves the sound of earbuds, ala harman target, oratory1990, toranku, diffuse-field, etc.
- Take the heavy lifting out of what sounds great and allow users to quickly improve their earbuds and make the more specific adjustments themselves.
