The same ones that came with your iPhone, iPod or iPad
Sound quality: Chances are you’ve spent hours listening to music through these little white headphones, so you probably know the sound quality is decent but nothing special.
Road awareness: These allow you to stay aware of things around you because they don’t block your ears from the elements. This is a major safety upside.
Ear grip: They tend to squirm but can make a decent seal if placed correctly. Expect to adjust them during a run.
Bonus feature: The control buttons on the cord let you adjust volume and skip through songs without fussing with your iPod.
