New Simgot EM10 arrived: https://www.linsoul.com/products/simgot-em10-1

Yes, regretted actually twice. Initially I bought M size, it did not provide the proper fit. Next pair was ML, which did provide a better fit, but the bass diminished and trebles got more pronounced My usual setup: FiiO M11S, Geek Wold GK100 with DIvinus Velvet eartips M/ML size. I also tried...

Technically, the play market version is for android phones, not for specific FiiO players. So, the best way to update the FiiO Music is to update via the application itself or download from the fiio's website and install manually...

Looks like it. I wish they'd just leave the highs untouched, but add the same amount of sub bass as above. I guess EA2000 would be the right example for this kind of tuning? Maybe not as much bass as "Sample 4" though?

Supermix4 - more sub bass than EA1000, I hope?

Quadbrid:

Eagerly waiting for your comparison between the two, especially if the highs were tamed.

Have been using the cable FIIO LC-2.5D for 5 years, so far no issues, I don't change cables periodically, but do adjust the position in the socket by turning around its axis for a better comfort though.

The price for GK100 is $150 now during the Black Friday! And I already spent my $200 on Simgot EA1000, a hyped one recently, which did not meet my expectations, tbh...

I guess the damper (foam insert) tames the S12's brightness in S12Pro, especially this 8kHz peak. I have both S12Pro and Z12. Z12 has a bit more lower bass and slightly more highs, at least, hi-hats/cymbals are not that veiled.

And if you format the card via a Win/Lin/Mac computer - what happens?

Thank you for your reply. Being 45 y.o. I also like a brighter sound, which younger people may find too harsh/hot. I wish I could test drive all of them, but under current circumstances I won't be able to do that for the next couple of months.

Thinking of going full-size planars. I currently own Beyerdynamic DT990 600 Ohm, FiiO M11S, FiiO FH7, Letshuoer Z12 (main ones now) and S12Pro. Do you think that M570 will be on par or better than this setup in terms of the sound signature I like, i.e. V-shaped? Thank you.

you mean Divinus, not Azla, even though both are from Korea?
