All I can say about the Bose soundsport is they seem a bit flimsy to me. And where the control buttons are placed I find it hard to reach. That's me.... AirPods are fine and convenient. The Bose sound a bit better because of the way they sit in the ear.
If the SoundSport feels flimsy to you, can you give an example of a earphone that doesn't seem flimsy to you? I'm just trying to get a sense of where you are coming from, because to me, the SoundSport seems sturdier than most other earphones I've used.
