Tozo openreal headphones. $40 I use them 8 hours a day. They let you hear everything around you while also being decent headphones. In the office where I take phone calls they are much more ergonomic than my Bose QC45s which I used to wear the same amount.

Under $1000, my bambu labs printer. I've fixed things, made things you couldn't buy, it's a staple in my house now.
