i cannot complain about the sound, the noise cancelling, or any of the awesome functions of these earbuds. that being said coming from the galaxy buds+, the interchangeable wing and tip design actually keeps the earbuds in when i am working out. doing cardio with this new pair is not the best. considering that i mostly use headphones when i am exercising and a sound system otherwise i have to give these three stars. go back to the customizable design, but keep the awesome features for the next ones, please. if you have "normal" sized ears, you won't have a problem, and if you just want these for walking around, or commuting then they work very well.
