Faaeal Datura Pro
version 1.5 bass and neutral editions
I do not have this bud in my possession, so I haven't given it a listen yet.
@cenizas provided the graph for correction and
@furyossa is giving it a test run before chiming in with his impressions. Thanks to both of them for their help.
The bass roll-off on this bud is pretty significant, so there might not be much difference at all between the bass and neutral versions for this model. Also, given that the correction curve is pretty extreme, depending on the driver quality, you might need to run this at 40% eq strength on wavelet. On peace/apo in windows that will equate to hitting the "compress" button 3 or 4 times.
Ok, here we go. This may sound a little exaggerated, but it's perfectly normal when you happen to feel goosebumps on the first listening

Do you know what you did? You have surpassed yourself. You brought the dead sounding earbuds back to life. BOOM!!!
I can't describe in words how bad they sounded before the correction. Like total garbage. I just don’t know how people praised them.
When they apply this correction they will know what I am talking about. When you turn up the volume, you start to feel pain, a distorted sound was unbearable.
I bought these earbuds last year as soon as they came out, they went through the burn-in process (> 40h) without any improvement,
and I didn’t listen to them for even 1 day in total. It is no longer worth talking about bad things so let's talk about good things.
First of all, you need to call the FAAEAL and let them know what you have achieved. Send them a file to hear how should sound flagship earbuds.

Man, seriously, no matter how they sound now, I’m not an expert at judging true sound quality, but I can honestly say the difference is HUGE.
Let's be honest, with this look and build quality they are definitely worth over $30 and with this sound quality (after correction) worth 3 times more.
It can rank easily with earphones in the price range of $100.
BTW...You made a much better correction here than with HE150Pro, maybe because HE150Pro already sounds good and not need too much correction.
If by any chance you have changed the target curve, try again with HE150 (female vocals are a bit thin).
Anyway...I used these PEQ files with Peace. For me personally, no compression is required, only preamp = -6dB.
In fact, I think it's better not to touch anything because compressing only restores the original bad sound.
I didn't notice any difference between the "neutral" and "bass" version. You can leave these "neutral" adjustments.
I was right when I said that this driver has great potential. The aluminum they used as a coating proved to be really good.
If I'm not mistaken,
Meze Rai Solo used pure aluminum for the driver's diaphragm, but the technology itself is much more perfect.
They stated the following benefits of aluminum, which can be noticed on the Datura Pro model:
- Low total harmonic distortion

- Clear mid-range

- Outstanding reproduction of low frequencies

I hope that based on my description you can make a purchase decision.
I don't know if it's up to me, but it still feels like the vocals are a little thin. I guess it’s because I don’t use compression. My bad

That's all for now. I am really grateful for all the effort and help around “reviving” the natural sound of earbuds.
