V-shaped tunes 660S seem kinda oxymoronic when the appeal of the 660S is the de-emphasis on the lower end in favour of vocal clarity and prominence. haven’t looked at the graphs but from what you describe it sounds like they just kinda inverted the FR.

i just use them for casual listening my more referential headphones are 660s (which themselves have recessed highs and quite a bit of bass roll off.) Besides i think the other commenter basically just said the actual sound quality issues i have in balanced mode is an EQ problem, I’m using something to EQ that isn’t supposed to be used that way.

nah the tuning is correct and i’m using it on apple devices but if you look at the frequency response it’s like a 30° line going into sub-bass and the highs really fall short.

i have the airpods pro 1 and i do agree the tuning is shockingly neutral. AirPods Pro might be probably the best purchase for anyone looking into airpods because they’re pretty affordable and make for some of the best true wireless earbuds. i really love mine

we get those bullshit preset EQ settings but they’re pretty shit. and their locked down ecosystem means you can’t run a third party parametric EQ. i suppose lowest common denominator consumer will always be apple’s priority

that would explain all my problems lmao, do you know why this is? Just a limit of being able to change the tuning on the fly perhaps?
