As a runner, I'm always on the lookout for functional, lightweight headphones that won't slip from my ears mid-workout, and the MDRAS20J Active Style Headphones ($20) definitely fit the bill. I have to admit I was hesitant when I first placed the loop-hanger design around my ears, as I usually prefer simple earbuds. After a few long runs, though, I appreciated the secure fit. It was nice not having to push my headphones back into my ears every other song, and the convenient cord clip kept the cords from swinging side to side.When it comes to sound, these headphones are ideal. They certainly don't cancel the outside noise, but for the price point, I was pleasantly surprised by their clear, solid sound, and I didn't have to blast the volume to drown out my treadmill. The bottom line: if you're looking for a practical, affordable pair of headphones that stays put during longer workouts, then the Sony Active Style set is a great option.
