Bro.. you're literally wearing them backwards. You're putting the right IEM into your left ear.
Don't say things like "perfect for audiophiles" when you don't even know how to put IEMs in your ears. I can guarantee you there are better IEMs under $100 from companies like Moondrop, truthear, 7hz, kiwi ears etc.
This is kinda hard to explain, but there are also some parts in the article that are complete nonsense (and anyone in the headphone hobby could tell immediately), but to normal people those parts probably look coherent enough to not question them.
Overall this article feels like someone who has just gotten into the hobby (but doesn't really know anything yet), trying to sound like he knows what he's talking about. It's gonna take a lot longer to understand what makes a headphone good, how to show how good a headphone is, the science involved in headphones, what the best headphone is for every price bracket, how to judge the quality of a headphone and compare it to the others on the market etc.
