Interesting question actually.

The ones you mentioned look quite good and looks like a great idea for people in your situation where they don't like carrying an MP3 player around. I personally don't have one of these so can't give you my opinions from experience.

What I would personally look for is COMFORTABLE, especially where the earbuds go in. I would imagine having them in your ear while doing training or at the gym, you would want something quite comfortable otherwise it would be very irritating. It's hard to tell from the picture until you try it on for yourself and see how it fits and how heavy it is I think. Personally, I would probably go with the Black (first) one as most of the weight sits on your head while the green one wraps around the ear and hangs out the back. That's just my opinion that's all.

You can also look at some more from LightintheBox here too: Sports MP3 players from LightintheBox. They look very similar to what you are looking at from TinyDeal anyway.
