I used these on my run as I lost my last pair and needed a replacement. They are super easy to insert and stay charged the whole time, as I run long runs. I never had to adjust them and the volume evened out very well so that I never had to turn the volume up or down from my phone. Will definitely be using these as I continue my long runs.
Easy to turn on and off by simple touch to the earbud. Connected without an issue and charge quickly.
