I did 4 and 6db low shelf , itâs the way the Heyday replays for me just doesnât hit my sweet spot.

Is it dry? Not enough oomph? Not immersive enough with its stage? Or is it mostly frequency response related for you?

You gotta call it how you hear itâŠnowt to apologise for.
Its neutrality is a double edged sword and i can see why it might not be everyones cup of tea

It does lack oomph.

I think the Heyday is exactly what it advertised a smooth natural sound.
Thatâs itâs Achilles heel. I wanted to try this sound signature and found this Planar is not for me.
The PR1 and Heyday graph looks similar up to 6k the added note weight on the PR1 is noticeably better to me.
The Heyday comes off as dry and sterile. Itâs the vocals that killed it for me they donât sound correct too thin.
!
Also when people say it has good stage it really doesnât not after listening to the C3, Obsidian OH10, EJ07M, and certainly not compared to my GS SE12.
Itâs planer 2 dimentioal like my biggest complaint with the Timeless.

The HeyDay is close in bass energy to the Timeless in all 3 graphs and I can say for sure that I didnât think Timeless was bass light, maybe pillowy in impact but it could rumble quite nicely, especially if EQd.

Difference is the heyday doesnât have the pillowy nature and is as such can sound like it has less bass as a result which it doesnât.
So itâs got less decay/faster transients? Yeah that can work towards giving a drier sound. So it seems the HeyDay should be paired with a warm/v-shaped source.
Thanks for the comparison graphs thatâs wicked!
Bass wasnât my issue , I agree you could if you have the ability and inclination to do so. In my pursuit to get to like this IEM I did that added at first a 6db low shelf and then lowered to a 4db.
My issue was Chris Reaâs voice sounds like someone is squeezing his balls and he is singing one octave higher than he should be. Female vocals are worse IMO.
You could also use narrow bore tips , I donât as I find it kills the stage.
AZLA short crystal or BGVP W01 were the best pairing but the Heyday has a fairly short nozel and went through my gammet of stock. Same as cables I settled on a Tripowin Zoe tri metal to add more note weight as well.
I was just saying to myself and to Kilo my dog that for $200 USD I could buy a
KZ PR1 PRO $81
Tin HiFi C3. $49
QKZ Q1 Modular Cable $16
Nice HCK sweet case $20
Same Modular Cable as Heyday $30
BGVP W01 Tips $2
Leather Cable ties $2
Total =$200
Value for money 10 x Heyday and better sound with a ton more enjoyment factor.
I am old and opinionated so take this with that information LOL

Itâs all a matter of taste. Someone might like a vocalist who sings like his balls are being squeezed 
. If the female vocals are worse, the women probably do something else to them, for example, they pull out their hair to scream while singing 
.
But kidding aside! Still, work has gone into making this IEM and I respect its neutral nature. Apparently itâs not for everyone, but only for real audiophiles!

Glad you could salvage the situation. The UP is pretty sweet.
