In my experience the vast majority of cheap knives can’t hold an edge at all. The super budget stainless used is just too soft. At the same time I can find many in the $70-100 range that do considerably better in that regard - I sharpen them 3-4 times less frequently.
I prefer to spend a little more on the 1-2 that get the most use.
Planar magnetic headphones that start around $200 (monolith m1060) will do that
