I rarely buy anything nowadays. It's rare that I find something that really enhances my quality of life.

That being said, a few years ago, I bought noise canceling headphone, and it's very useful in noisy environment.

Also commuting by bike made a huge difference in my quality of life: a 150 euros bike served me well for almost a decade! Unfortunately, it's not possible everywhere. I recently moved to a new city with barely any cycling infrastructure and I find it too dangerous to share traffic with cars.
