I actually really like this haha. Hope there can be constructive comments on this.
My opinion: it's an open-ended question, so context is important. Honestly, in the realm of "truly wireless" IEMs, they're definitely not the super tinny, horrible things people make them out to be. They function just fine (although I personally like the Bose ones better, but they also cost about twice as much as the Airpods). If I was in the market for true wireless IEMs they'd be on there, but alas, I can't stand IEMs because I don't like the feeling of having something in my ear like that.
