Bought these SoundPEATS as a gift for my sister but put it through a quality test before wrapping. These earbuds feel really comfortable, and more importantly, secure. They would be very suitable for exercise as they feel very stable. I liked the ease of pairing and ability to start using straight out of the box. I also like the ease of the controls with a simple tap on the multifunction button, especially in comparison to my current SoundPEATS which require a more assertive press of the button for the various controls. On first impressions, these earbuds appear to be a great buy. Can't really comment on battery life of the buds and charging box, time will tell.
