I'm a fan of the Bose SoundSport buds. They are BT from the source as well as to each other. No wires, cradle, or band to mess with. They produce better quality sound than any other sets I've tried. The battery life is starting to wane a bit but I'm into my second year of daily use so no complaints. There are two additional charges for the buds in their carrying case.
Disclaimer: I've used many sets of BT over the ear and buds but all of a cheaper nature excepting one. I have a fairly expensive set of PowerBeats3 that I have not used since the purchase of the Bose. They work fine and have a great battery life but they sound cheap. I've owned thirty dollar sets that sounded much better. I've only experienced the top end offerings through them and the Bose. Bose win hands down but I don't know how they compare to other higher end units beyond the Beats.
