Speaker quality

I bought a Mac Pro 2018 for my daughter for college Aug 2018 & her speakers had some kind of static to them after a few months. Then I bought an iPad Pro 11 in 2019 & static is now plaguing these speakers. Apple care will fix this issue after they keep it for a few days BUT why aren’t the apple products (which aren’t cheap) coming with quality equipment? This is more 1st apple product & I thought I was spending all this money for a quality system but it will only do quality pictures/videos but not sound. Has anyone had speaker quality issues? It sounds like random static occurs. I’ll just record audio on my Android but this is sad.
