I really don’t know how you tested them. But looking at the graphs, they apparently hit the target kind of good. They are also apparently in every other aspect of sound quality better than Airpods 2. I had them both for a year (first one year the sound cores and then for another year the AirPods) and the test of the sound cores seems lacking. Yes, they only cost 50€ but they really really suck in sound quality. I’ll compare them to the AirPods since after this website they’re better! The Soundcores sound like you’re listening through a tin can. They lack any kind of bass. Also basically all ranges are lacking. Apparently, they hit the target better than the AirPods but that’s just bs. I don’t know if I’m just stupid but the whole test of the soundcores really seems misleading. They don’t sound good at all! They’re alright for 50€ but it’s still the fact, that they apparently hit the target better than the AirPods, which sound much clearer, have better base, better highs, better mids, everything!
