I think I can confidently say that Lobkin headphones/earphones are perfect headphones for my workout! The battery life of these headphones is pretty good, lasts about 9-10 hours (depending on your usage). They fit in my ears comfortably. I had no pain whatsoever even after wearing it for a long period of time. The sound isn't the most awesome but it is fairly good.
The clips are pretty good, if you are into running or working out or simply clumsy. :) I love them!
