Sony Mdr-As20J Active Style Headphones with Soft Loop Hangers (Black)

best running headphones so far! maybe because is comes with a clip, great idea! the left side tends to vibrate slightly in my left ear (it doesn't fall out), perhaps because i use earrings in that ear but, turn up the volume, and you can't really tell.

Earphones are exactly what i was looking for, These fit my Iphone and use them to work out. Great quality. Sony earphones will last a long time and they go through some heavy use.

I run half marathons and marathons so having my Ipod Nano is a NECESSITY!! The Sony Mdr-AS20J Active Style Headphones work well with my Nano. They're very comfortable on my ears, sound is great and I don't have to really adjust them during excercise or running. Highly recommend!

Thought I had found something that would be comfortable and stay in ears while running; did okay job with that, but after first month or so, one side just died on me so I was listening with one ear and the quality of sound deteriorated on the "good" piece after about 20 minutes. If sweat gets in your ear, then you cannot hear anything from this unit. That was my experience.

I am VERY happy with these. A GREAT price and great sound!! I use them constantly -- while riding a bike, on the train, or just sitting at my computer. HIGHLY RECOMMEND! You won't be disappointed. My friends are a little confused when they try to put them on but it's all good...
