Dear Colleagues,

I am preparing study on the using of social public information on territorial behavior and distribution of birds. I would like to broadcast songs of forests and farmland birds . I am very interested in opinions of more experiences colleagues about the kind of device used in playback experiments. In my study I would like to use mp3 player (I think about Creative ZEN X-Fi3) connected via bluetooth with a portable speaker (I m not quite sure which to choose...). Do you have idea which producer/ model is the best (for example which portable speaker works long on batteries) , have the idea about price-quality ratio and which set of products would you recommend for using in field conditions.

I will be grateful for any suggestion.

All the best

Piotr
