https://www.amazon.com/gp/product/B0748JM8M5/

Meet SoundSport Free headphones, the first truly wireless in-ear headphones from Bose, made for the toughest workouts. They are engineered to deliver clear, powerful sound with nothing—not even a single wire—in your way. So you can run, jump, dance, lift, twist, turn and achieve your personal best every time you use them.

These SoundSport Free are awesome! Sound is amazing, I purchased another brand for running and working out but the sound was very hallow and i wanted something with more base. After some of the positive reviews I’ve read, it truly is amazing!! The three ear piece size is great, I have small ears and their smallest ear piece fits perfect. It stays in pretty well, does not budge when i move or work out. Blocks a good amount of the outside noise, it’s a hefty price to pay for wireless ear buds but it’s well worth it.
