These red CCA's are my entry into IEM's. While I would prefer wireless in-ear devices, this works just fine for listening to music on my PS5 while talking to friends. The mic has never given me an issue, and I can generally hear game audio rather decently (tune it and could maybe turn out better) as opposed to music, which is even better to listen to. Seeing as most of the phones I've had don't include a headphone jack, I tend to use them with my PC and consoles, with apple music and their equalizer. Bought them in 2023 and has not lost it's sound quality since then, though some part near the Left-Right plug has turned green, since the piece is translucent, and not black, like in the product images. Still have a box of KZ EDS waiting to be used, still won't until these are done and dusted.
