That's actually pretty reasonable for stereo Bluetooth earbuds. Most of the ones I've looked at recently run more like $200-$300.

Where are you looking? aliexpress is the way to go.

On Amazon. But I also wasn't looking very hard, because for music I have proper headphones, and during my commute I prefer not to block both ears in any case. Discovering the existence of wireless stereo earbuds, and whatever sense I have of their price range, was really just a side effect of looking for something I could stick in one ear and play podcasts through.
