best mp3 player I've owned

Love this mp3 player primarily because of my special needs. If you cross fit, parkour, obstacle course race, run, or do some type of exercise that causes you to jerk your head around while working out you'll want this. If you've ever felt the pain of jerking your earbuds from your head while trying to listen to music, you'll want this. Basically, the mps player is integrated into the ear buds. That means there is no cord to jerk on. Okay that said it seems a little unfair to criticize a technological advancement like this. But, I have to say something. So here's the deal. The next step for improvement is bluetooth. As it is now the mp3 play plays what's loaded on it. What I'd like to see happen is for it to wirelessly connect to an android. That would allow me to conceal a phone safely in a back pack or strapped somewhere and stream pandora or some other music. It would also allow me to take calls while working out. Furthermore, the battery tends to run out. They need an auto off feature. It often runs on its own and then when I go to use them, they're dead. Overall though, love these. Better than any mp3 player I've ever worked out with. Also, their water resistant, which allow me to not worry about them in my often messy workouts.
