These are the headphones I use when I run. They are super comfortable, small and the battery life last for over a week!
Earbuds that have good sound AND stay in your ears while you’re running is tricky. I got these ones from Plantronics almost a year ago and love, love, love them. They’re comfortable, they don’t fall out, and they’re really small. Also, the battery life is very long. I only charge them every week or two, and I’m using them for at least thirty minutes every day.
