It is again complex topic. Again related to HRTF for in ear monitor listening, but what is more important related to human hearing sense being specialized and most sensitive in selected range of frequencies - see A-weighting of sound pressure for example. Subjectively you perceive some frequencies as louder than other even though the raw measured SPL by microphone is the same.
Also FR charts are inherently flawed when normalized at certain frequency. You may imagine that the measured SPL of white noise is different for different sets. And this is completely omitted in FR graph. In the end you may want to push some sets to higher volumes than other (because your perceived loudness is lower than for compared set) and sets with let’s say bass shyness based on FR are not there in reall life. I don’t know if that is understandable or not the case is that measuring based on white noise’s SPL is also kind of stupid as music is not white noise, but a sum of different frequenies in not even quantities. Maybe pink noise would be better, but still hard…
Also keep in mind that measurement is based on incremental increases in frequency for the white noise.
Example:
Whats the DB when we play 20hz?
ts 70db
Whats the db when we play 21hz?
its 69.
Whats the db when we play 22hz?
its 68.
etc…
But with music, we dont listen to a single frequency. We listen to everything, and our ears also hears stuff differently when everything is playing at once.
Sorry to hear the Tea braking down on you, but make sure to not throw the Tea away though. nymz’s Tea is an artifact of IEM history. So worst case you can still put them in a display case or something like that.
I refused to spend a lot of money on IEMs for a long time, because they would just regulary brake for me. Probably went through 1 set per year or so. But since the CCA C12 lasted for several years, I decided to go for the “very expensive” Aria. After that I got addicted and spent more and more, but still with the understanding, that my current kilobuck IEM can brake down any moment and I don’t expect a chinese company to honour any kind of warranty.
Exactly, that is what I mean, if you have 3 different sets, you set the volume for each of them at comfortable listening level for the same song and then measure each of them for FR at that volume it is very unlikely that 3 charts would be crossing at same frequency and level.
Also, you can check your personal hearing (like perceived hearing) in APO + peace for Windows where you sweep through each frequency and manually turn the level of volume down until you can’t hear the sound. You would see how uneven the chart would be (that could be a base for some further compensations in EQ)
Respectfully gentlemen, I know about different people’s ability to hear, I know different frequencies are heard differently by the human ear, the need for the Harman curve, etc. But look at that graph please. IF I bought a speaker for my listening room I would be bragging to my wife about how much money I saved because look at this speaker, we will not need a subwoofer with this baby!!!
You can choose another low frequency instead of 20 Hz and test it, there are plenty of test tones around, I used quite a few and the Kinda Lava, when it tries to play down anywhere near 20 Hz has to be cranked way up to hear anything!!!
The graph is not telling the truth for my set, don’t know about the Mahina but I doubt it.
God Bless,

Honestly, I think that ability to hear different frequenies differently and very different compensated perceived volume for in ear monitor, headphone and speaker perfectly explains your example, but on the other hand you may have a damaged set.
Other alternative that may be implied is that all measurements of IEMs all wrong. But if you look at basically any IEM (or average IEM) it would have higher bass or less roll off than an average headphone or probably even more than basshead headphone.
If you have time I suggest comparing test on this APO + Peace for IEMs you have, headphones you have and speaker system you have (preferably close field monitors)
Also - you may not have perfect seal that is necessary for good low frequency reproduction in IEM, check if you have better results with foam tips
Sorry Wayne, I can hear fine with regular listening volume on both sets. Not sure what else can I add at this point, but I think you should try to flip the Kinda Lava as it clearly doesn’t fit your needs.
Yes, for sure. This is due to the seal giving iems and edge and also with how brands like to tune stuff, it is definitely possible to have sub-bass rivaling or even more than most iems with a hp. (I did it after all.)
Yes. Spanish!! There are few reviewers from this country. You can count them on one hand. It may seem idiotic, but southern Latinos tend to have different preferences than Central American Latinos. Spaniards tend to be closer to the preferences of the USA and the rest of Europe, although the problem is that there are so many reviewers from these Anglo-Saxon countries that it’s crazy.
I was able to see the Mahina review. It looks spectacular but its price here makes it more of an A+ option or basically an end game for me. The biggest problem with the Mahina is its price. 750€ here.
I’ve seen the Ej07m at around 500€. When looking at iems of these prices it seems we tend to forget and underestimate the price differences. An Olina that is 70% of the Ej07m costs 1/5 of its value.
I ordered an Openheart cable last week on AliExpress. I haven’t received it yet and I’m not getting my hopes up just yet but it does look similar.
I was trying to find a cable similar to Timeless for the P1 Plus.
the case is that measuring based on white noise’s SPL is also kind of stupid as music is not white noise, but a sum of different frequenies in not even quantities. Maybe pink noise would be better, but still hard…
