Self-fulfilling in what way?
I've probably spent a hundred bucks on fifteen pairs of Philips over the years. And they're cheap enough that I can keep a pair in my bag, a pair in my house, and a pair in my car. Most of my listening is podcasts. They sound fine for that.
In contrast, I only have one pair of noise canceling Bose headphones which cost 3x as much as all the Philips put together. They sound great and are wonderful for the train to work, but they were also very expensive and I don't run with them.
