„Preferably ones that are works with poorly mastered materials but still have good details and clarity.“
Interestingly, this “problem” is part of my research.
And unfortunately I have to say:
„It is still not possible to “convert shit into gold”.
As an example of this I would like to mention 3 music tracks that were really bad recorded:
1.) Britney Spear’s “Toxic” from the album; In The Zone.
2.) Miley Cyrus’s “Malibu” from the album; Younger Now.
3.) Canyon City’s “Fix You” from the album; Refuge.
Testet with 16 different In-Ears at Home, about 10 at a dealer with whom i have good contacts, including the CA Polaris.
The whole thing with about 25-30 different tips in my size.
In addition 4 pairs of Bluetooth In-Ears from my collection,
with the result = määhhhh
No matter if it is played by Tidal Masters or Amazon Music HD;
It doesn’t matter whether it is played by a $ 2000 headphone amplifier or a cell phone. It always sounds bad, or at least unsatisfactory!
These songs can be ironed out a bit with more affordable in-ears like the “Venture Electronics VE Bonus IE” for around $ 18 or the “BLON BL-3” for around $ 35.
Otherwise there are some Bluetooth in-ears that can “spice up” the very thin sound quality, such as the “Bose SoundSport Free”, which I cannot really recommend for higher quality music.
In my opinion, the CA Polaris is not really fish, not meat. He is not really an audiophile, but also not a pure bass blush. Just too expensive to just have fun and not really enjoy the quiet sounds.
As Ohmboy mentioned, the IKKO OH10 is a pretty good choice when it comes to clarity, definition and bass and with a good price - performance ratio. But with slight comfort restrictions due to it‘s weight.
One level above is the Fiio FH7, which brings a little more structure into the bass area, penetrates a little more into the depth of the room
and overall is a bit more harmonious. And lighter!
However, both mercilessly uncover badly mastered pieces of music and that’s no joy to listen to.
My recommendation is therefore to work with 2 in-ears! One for the enjoyment - with bass qualities and one to “endure” the rest - also slightly bass heavy.
