Our take on the Sony MDR-AS20J

by Kristen Schaub
Sony

Sony made the MDR-AS20J sport-style headphones for active use. The loop-shaped ear hangers comfortably fit over a wide range of ear sizes, and keep the earbuds in place even during intense workouts. A four-foot cord gives you plenty of room to move around, while the included clip secures the cord to your clothing. The low-impedance design features 13mm drivers for high-energy sound with virtually any portable audio player.

Not sweatproof!!!!

Written By RichR, NY, NY on Tuesday, September 20, 2011
 
I thought I found the perfect workout/running headphones, and was thrilled at first. Super-secure, and still let some acceptable amount of sound in which is much safer when running outside. But I quickly learned that they are not sweatproof at all. First pair last about a week and then one ear went. Returned them and the second pair lasted a week and a half. I really wanted them to work, so I tried one more time, and the same thing happened. They seem to short out from sweat.

The ear phones work well and I'm thrilled that I don't have to stick them inside
my ears.
