JayBird bluebuds x - the best in its kind!!!!
Totally agree.
I had the Jaybird Freedoms for the last year, and just upgraded to the Bluebuds X last week.
Easily the best headphones I've ever had for working out... no wires, great sound, amazing battery life, lifetime sweatproof warranty and great customer support from Jaybird.
They stay put regardless of what I am doing.
They are pricey, but worth it.
