IPOD Pocket Speaker

I'm looking for a small (about the size of an Ipod) speaker for field work. Fidelity and volume aren't critical (its for bird calls). The selection via web search seems to be pretty damn limited--any thoughts?

 

Hi Uro. Yes, they are important to a point. The issue is it doesn't have to be loud enough to play at a kegger, and the fidelity doesn't have to be equivalent to high end home stereo stuff. Remember, birds don't have real big brains. But obvoiusly, it has to be better than those little speakers that come in those musical or speaking greeting cards.
