I will wear them to the gym on Monday and give an updateOk, I did wear them at the gym this morning for 90 minutes-30 min on elliptical and 60 min of upper body workout and I had to push them in just twice. I wear them for quick trips to the store, long walking excursions- like sight- seeing when traveling, etc. Nice color, good product and quality. The lightening cable does charge even with the case on. and we both are satisfied having paid a fraction for two sets than what one pair of name brands would?ve cost. It?s strong, durable & since I got this case I have not lost it once! I also bought the Sansha teaching sandals in black in a size 10 (they run small and were awkwardly long and narrow. No way to adjust mic monitoring. I just put my AirPods in their case and then slide the case into the charger abd plug into a USB port. it is strangely bumpy and feels weird.
