I used the buds to listen to music during my workouts specifically martial arts. I bought new and these were clearly returned at some point. For a long time, Bluetooth microphones did not do as expected when dictating in voice recognition software such as Dragon Professional Individual. Brilliant footwear! was this just a last effort to once again make the player feel as crazy as the storys two characters ? Wish I could afford every color. I really like how the earbuds lock into your ears. Now I get to see a scratch on my top tube that wouldnt be there if I stuck to my original method of using painters tape. This renders them completely unusable. They are snug, but not too snug, like how I think performing shoes should be.
