It’s so interesting how subjective sound is. While the APP do not compete with super cheap CCA C12 and a Fiio adapter, they are subjectively to me the best wireless Inner Ears. Light, small, hyper easy to use on Apple devices and while I bemoan the lack of an individual EQ they sound balanced and bassy, especially with current electronic music delivered by Apple Music. They could be a bit more punchy when it comes to old ripped CDs or 80s tracks and as all IEMs suffer from muddy guitar music production with lots of shrill midrange buzz sounds in the mix, but the mix of versatility, ease of use, really good sound for their size and driver system has made them my daily headphones instead of Sony XM4 (and I cannot say enough bad things about Sony), B&O and so on. But I personally like a V-shaped sound, while others prefer super neutral clean linear audio, so tastes just are different.I don’t even find them comparable to older basic Apple earbuds, which were bad enough but who knew they could get so much worse. The compressed audio and over processed sound is plain bad. I wouldn’t dare compare them to anything with larger drivers but these same issues also affect the AirPods Max, another reason I never bought those either.. It’s the common electronics and protocols in use that are the problem. I didn’t even mention the issue of them falling out but now that you mention it, that too is a nuisance. They never really feel secure. I am using them with the smallest included tips for the snuggest fit so I can really jam them in there and they will always find a way to work themselves out or need constant readjustment. The product category has potential but current execution is lacking big time.
I could absolutely do without any kind of pulse or camera in my headphones though, PRO should mean audio and not sports or whatever. More drivers, better soundstage, even better ANC, less weight, better FindMy and individual sound profiles would be nice.
