In my experience, there is a clear difference between budget and more expensive earbuds, but the budget ones are perfectly fine.
I've been using the Pixel Buds for almost a year and bought a $40 pair of Ankers as a back-up. The Ankers, despite having high scores on Amazon, sound tinny compared to the $130 Pixel Buds. The difference is very noticeable going from one to the other, but on their own, they sound good.
Budget earbuds are also less likely to have wireless charging, which is a big deal to me but may not be to you.
