I didn’t want to listen with them in preference to my S12 Pro ($135)

Planar timbre :scream:

Give the 2024's a try, I love them as they're much better than S12 OG (imo). But as much as I respect what they can do especially for what they cost, I much prefer to listen with others that cost a lot more. If I'd heard them first (and was wise) I could possibly think they are all you need though.

I have retuned my S12 Pro with what I understand is the nozzle tuning used in the S12 2024. A medium damper foam and the same grill as in the 2024 which is very much finer than the one on the Pro and, based on measurements by a chap big into S12 tuning, plays a role in the tuning.

The difference is very noticeable when comparing tracks with problematic sibilance.

I wouldn’t be surprised if I have essentially tuned them to be near identical to the 2024.

I don’t hear the “planar timbre” at all despite that they are my only planar set. Nothing leaps out at me even coming from other set that I have listened with for hours that are of different driver type and much greater cost, if that matters 😁

I am of the opinion that “planar timbre” is just the very crisp treble and perception because everyone says they have it. That is one nuance I don’t buy into, same as BA timbre.

Not wanting to argue at all, just comparing notes, but why doesn’t the 2024 have planar timbre when they are essentially the same IEM with a slight tuning variation, it is still a planar.

My S12 OG had very noticeable planar timbre, it spoilt an otherwise superb, for the price, iem and I got rid. Was hesitant to buy the 2024's but some others who's opinion I trusted said they were much better, and I can't notice any.
BA timbre I agree, on cheaper sets they can sound a little 'metallic' maybe that's what people mean?

Not wanting to argue at all,

Of course, perish the thought :relaxed:

Gidday mate,

It might be as simple as that but there seems to be something in the nuance of the bass in particular when comparing DD, BA and planar drivers in IEM, and BC come to think of it.

Again, I happily admit I might be getting sucked in by bias because what I hear is essentially what everyone parrots.

However, I am more than happy to buck the standard line, in fact I like to where I believe it is warranted, but this is a situation where my feeling (not that we care about those 😂) is that there is something else going on between driver types even if they have a audibly very similar bass quantity regardless of how they might measure on different measurement set ups.
I suppose you are using exactly the same or very similar ear tips for both IEMs?

@JamoBroGuy
We rarely know what else is audible from looking at FR graph. Distortions can very well be audible. We often talk about THD, but of course there are other distortions that we never see measured, so we have no clue how big they are and if that's audible.

But again, it doesn't matter because the FR is probably never going to be the same between 2 headphones or IEMs at someone's eardrums for many reasons. So all the conjectures and empty claims about speed, distortions, driver type or whatever, they lead nowhere. Nobody knows from some casual listening, and those who say they do, are wrong. It's very hard to get the right testing conditions(who wants to go push a mic against the eardrum to make the FR graphs or some other measurements? Not me!).

Exactly the same tips at present but even with different tips on both the sound signature differences are still very apparent. I certainly can’t swap tips to match the sound, not even close.

My S12 OG had very noticeable planar timbre, it spoilt an otherwise superb, for the price, iem and I got rid. Was hesitant to buy the 2024's but some others who's opinion I trusted said they were much better, and I can't notice any.

I have never had a cheap all BA set so I can’t really judge that aspect but for me the apparent driver timbre disappears when I stop thinking about the driver type. In my opinion and experience there is a strong clue there but of course that is just my position. Like everything mileages will definitely vary.

What doesn’t disappear is the difference in bass nuance I described earlier. Planar bass always sounds different to a DD and a DD different to a BA and a BA different to a BC although I only have one frame of reference to BC bass drivers.

That could be bias but I really don’t think so, I am very critical of myself with biases, I don’t like to kid myself. Of course I have no practical way to blind compare the IEM to see if I notice it without knowing what driver type I am listening with.

Frequency Response is the majority of the story. When you’re shoving an IEM deep into your ear canal, there’s physics at play, just as when you put a speaker in a room. But when it comes to the transducer separate from these physical issues, frequency response is the determining factor to the sound. You can look at the chart between two transducers measured the same way and have a good idea what their differences in sound are.

Maybe different impedance on both IEMs and need to correctly match the volume between both of them? Or, as Bigshot stated, even when you feel that both of them are placed almost in the same position inside your ears, maybe there is a slight difference... :thinking:

I am not sure I agree with the notion that the FR graph represents the sound signature.
Does anyone have that notion? Assuming “sound signature” means the characteristics (plural) of the sound then a FR graph only represents the FR characteristic (and even then, only under specific conditions), not any other characteristic.
Other measurements or measurements on specific equipment might indicate relative sound characteristics better than some but the common 711 measurements seen everywhere, even on the same gear, don’t seem to tell the whole story.
Unfortunately, this is one of the biggest and most pernicious problems/myths in the audiophile community, ruthlessly propagated by marketers and their shills for decades, ever since measurements started contradicting marketing claims. Namely: What measurements are actually measuring, what those measurements tell us and what they don’t tell us. At best a measurement (of equipment performance) can only ever tell us the “story” of that measurement (of that equipment) and provide a comparison with other equipment assuming a standardised measurement. A measurement never tells us the whole story, even if it were a perfectly accurate measurement it still wouldn’t tell the whole story and they don’t claim to tell the whole story!

In this particular case, the FR measurement of IEMs: I’m certainly no expert on measuring IEMs but the principle is universal: What does the measurement tell us and what doesn’t it tell us? As a relative novice in this particular area I had to go and look it up and the applicable specification for the 711 measurement seems to be IEC 60318-4 (I hope someone will correct me if I’m wrong) which states:

IEC 60318-4 describes an occluded-ear simulator intended for the measurement of insert earphones in the frequency range from 100 Hz to 10 000 Hz. … The occluded-ear simulator simulates the acoustic transfer impedance for the occluded normal adult human ear. However, it does not simulate the leakage between an earmould and a human ear canal; therefore, the results obtained with the occluded-ear simulator may deviate from the performance of an insert earphone on a real ear, especially at low frequencies. Moreover, large performance variations among individual ears will occur which should be considered when using the ear simulator.” - IEC Website, IEC 60318-4.

So, to start with, FR itself isn’t the whole story and a 711 measurement doesn’t even tell the full story of FR, let alone the whole story! Furthermore, the standard level for this measurement is 94dB SPL, which is way higher than a typical/safe level. This presumably helps avoid certain potential issues (such as SNR) and provides a required reference for comparison but again, doesn’t provide the whole story (of listening at a reasonable level).
How similar should the two IEM from the same manufacturer on graph below sound ?
I have both and the fit in ear is very much the same with very similar shells so I don’t believe there would be an obvious difference caused by insertion depth differences between the two.
As the previous paragraph indicates, the answer to your question is: There is a reasonable chance they will sound the same but they could sound significantly different. Because: Firstly, the graph does not tell the whole story and Secondly, even if the insertion depth in your ears of both IEMs is the same, it might not be the same depth as with the coupler and, the seal might not be the same (either between the two IEMs in your ears or compared to the coupler), both of which could also result in the IEMs’ performance varying significantly from the measurements.

Do you really believe these instruments don't make any appreciable sound above 4kHz at lower octaves? Have you never listened to music or how do you come to a conclusion like this?

They have harmonics 🙄

@colonelkernel8
Yes, you’re right to say that the two IEMs would probably sound very similar if not the same in the region @theveterans highlighted. HOWEVER:

That’s assuming those 2 IEMs will have that exact FR at YOUR EARDRUM. There are loads of examples of 2 IEMs measuring very similarly on a 711 coupler but as soon as you measure them on a more accurate measurement rig like a 5128, they’re actually different. So just because they measure the same on a measurement rig doesn’t mean they’ll have the same or even a similar FR at your eardrum (chances are you don’t have the same ear canal as a 711 coupler or 5128).

But you’re right to say that there isn’t some magical quality of an IEM’s sound outside of FR (and in the somewhat rare case where it’s audible, harmonic distortion). That’s BS.
Good point and it's one I overlook too often.

BA timbre is a meme. It’s almost certainly placebo from simply knowing that the IEM has BAs. Similarly to how people perceive copper cables as “warm” simply because the colour of copper is “warm”, people might perceive BAs as “plasticky” or “artificial” simply because of how the drivers look. They look more “artificial” than dynamic drivers.

Of course I have no practical way to blind compare the IEM to see if I notice it without knowing what driver type I am listening with.
The only way to do that is to hand someone an IEM they’ve never seen before without telling them what the driver configuration is (it should ideally have an opaque shell so they can’t see the drivers), having them listen to it, then having them describe how it sounds. So yeah, it’s tricky.

Furthermore, the standard level for this measurement is 94dB SPL, which is way higher than a typical/safe level. This presumably helps avoid certain potential issues (such as SNR) and provides a required reference for comparison but again, doesn’t provide the whole story (of listening at a reasonable level).
THANK YOU.
Harmonic distortion is also measured at these absurd volume levels (94, 104 and 114 dB), which tells us nothing about whether or not it’s audible at a reasonable listening level. I’ve seen people on ASR try to justify caring about how much harmonic distortion an IEM has at 114 dB because (paraphrasing) “music has peaks at 114 dB that only last a few milliseconds”. That’s only true if you’re already listening at 100+ dB (extremely dangerous) with particularly dynamic music, such as classical.

True. However, it’s useful as a point of comparison and it’s useful in the sense that it gives us a max measurement that can’t reasonably be exceeded and typically will never be attained.
I’ve seen people on ASR try to justify caring about how much harmonic distortion an IEM has at 114 dB because (paraphrasing) “music has peaks at 114 dB that only last a few milliseconds”.
By that logic, the answer to “how much harmonic distortion an IEM has” would be a few milliseconds worth!
That’s only true if you’re already listening at 100+ dB (extremely dangerous) with particularly dynamic music, such as classical.
Typically but there maybe some rare examples where the average level would only need to be around 94dB (peaks 20dB higher than average level). That’s academic though, as even an average level of 94dB is still well into hearing damage range and around 30 times higher than typical listening levels.

Definitly, as does tech like @theveterans pointed out.

Lots of factors at play IMHO. For example, a poorly tuned DD (not in FR sense) but where DD is placed on the shell with custom made sound guide/bores and crossover settings (if multi drivers) in a way that exhibits a distinct timbre (has to be fundamental + harmonics) that can fool me to suspect that this unknown IEM has BA drivers and vice versa. It’s a design/engineering trait of the whole IEM to tune a certain timbre (fundamental + harmonics) in the hopes of sound as natural as most people would perceive. So it’s really hard to just generalize BA timbre, DD timbre or even planar timbre without factoring how the sound travels through the IEM chamber
