So, not sure where to post this, but this is the Nothing Ear bluetooth set. I originally bought their open-air set for running and it works great.

But then I bought this and it's better than all the fucking IEMs I've tried. And it's not even close. Over fucking bluetooth.
Why are these so good? Does anyone here know what technology they used in these? I'm guessing the driver responds faster because they sound way, way more detailed than even audiophile stuff. Maybe they use some kind of processing to mess with the waveform input, like some kind of sharpening technique? Why is it so detailed? Anyone know?
