Don't listen to the assholes in the comments. Enjoy the stuff you got. Try for yourself, if you like them, then fantastic! If you don't, you can sell them and buy something else.

I haven't tried the other two, but I love my AirPods Pro, they sound amazing. I also loved my ZSN Pro X at the time I got them, they were my first pair of IEMs so I have some nostalgia for them. Good score mate!

I'll give you the first point. Chu was garbage, Quarks were pretty good, Quarks DSP are even better than that.

And lmao cope harder.

It is just another hyped cheap chifi IEM.

It is better than cheap IEMs from a year or two ago, but really nothing groundbreaking. Still loses to Moondrop SSR in the technical department, and tonality wise it's just a well executed V-Shape, it you're into those things. It's definitely a good IEM, but doesn't really come close to things like Titan S, P1 Max or Starfield.

Why is Chu irrelevant if you loved it so much?

I'm not terminally online so I don't know who you are

Just saying "X is irrelevant because of Y" is rarely the case in audio

I have 7Hz Zero, Chu and OG Quarks.

OG Quarks is the best tuned, Zero has decent technicalities, and Chu is straight garbage.

That is my opinion though, you're entitled to having a different one. Just your previous comment really ground my gears lol.

Always hyping whatever new set comes out and acting as if the previous one is completely irrelevant.

You are part of the problem.

I think these idiots are circlejerking over the Tangzu Wanker now. 7Hz is so outdated now /s
