The case feels more flimsy but I don't really care, I appreciate that it's smaller. These AirPods 4 are a marvel though, everything I've wanted in AirPods.
The original AirPods were very comfortable for me, but they would fall out easily if I did any serious movement like running. The 3's stayed in place a lot better, but were not as comfortable because I could feel the bulbous shape in my ear. And they would still come out sometimes on a run or if I bent over with my head upside down.
The AirPods 4 though stay in perfectly, I haven't got them to fall out yet despite my best efforts. They're maybe not quite as comfortable as the original AirPods but close enough and WAY more comfortable than the 3's or AirPod Pro 2's. Don't get me wrong the Pro 2's are very comfortable as far as sealed in-ear goes, but the 4's easily beat them for me. The weight difference alone is huge, the 4's feel like they weigh practically nothing.
