Its only for running. The sound quality is just average..sound quality is normal no extra bass like in other sony headphones. So purchase this if u need this only for sports activity.

I bought these headphones awhile back and they are my second pair. The headphones provide excellent audio quality sound. I use them in the gym and find the very comfortable in the ears.

They will not fall out of your ears and sound is good.

I bought these as the headphones I had with my phone just don't stay in my ears. These are great for the gym when I'm moving about. They stay in place as I hoped!

i really love it

[...]. They constantly fall off my ears therefore causing a real lack in sound quality. I definitely wouldn't recommend these to anyone. $[...] wasted. I bought a Sony product on purpose, expecting quality.
