Just thought I'd pass this on. I use a video ipod which can store zillions of calls & songs & video , combined with these pocket-sized folding speakers which are great in the field for luring on foreign trips, luring whilst ringing etc. Speakers run on AA's , batteries last for ages and are just so compact. And at this price give them a go. Apparently compatible with most MP3's.

Please note: I only recommend these for responsible use in the field if being used for luring
