Working Out with Bluetooth
When you go for a run, the first thing you might be annoyed by is the repetition of the movements and how discomforting that might feel to you. Obviously, going for runs is something that you definitely need to get used to, as is every exercise.
But beyond this, an annoying thing about working out is that the headphones with which you are listening to your music are hard not to notice when the cords are bouncing around haphazardly.
You do not want to have to pay attention to your headphones when you are working out and that is why Bluetooth headphones have become a boon of joy for people who work out and listen to music.
