I agree, this is a bit out of date, and more on the sub 15$ side of things, as far as the past few years are go. I love Moondrop products, they don't have anything like a piercing treble. Love my Moondrop x Dusk, Blessing 2, and just got wireless MOCAs, which beat AirPod Pro 2 for sound quality, for a third of the price.

I remember 10-15 years ago, it was impossible to find affordable IEMs that had decent quality, and Etymotic HF2 were like the first revelation, that hey, this is possible with an iPhone compatible mic. But, things have really changed, definitely thanks to the Chi-fi explosion.
