If a tree mutates and it produces a seed that is slightly flatter than its competition, then that seed will fall farther and the tree will be slightly more likely to reproduce over its competition. Repeat this for several million generations over millions and millions of years.
I’ve had the HyperX Cloud for 3 or 4 years and really like them. It felt a little uncomfortable for the first week or so after switching from a crappy cheap SteelSeries headset because of how good the soundproofing is. I bought my brother the Cloud II and he also likes it.
