Lol! The sound is good, but it ain't that good! Yeah, the "Apple tax" is really something, but their products really work well together. I have tested out some chinese knockoffs, and some of them sound good as well.
I've been through the same ting with cheap watches from Asia. They look great and work well.... Until one day, they just stop working for no reason. I treat them as temporary disposable smart watches now.
I wish I went about it with the same mindset. Every time I think “Maybe this one will be different”, and watch it NOT be different. Lol
