question about the m6 speakers.

First of all. doesn't it connect the meizu through a headphone jack and/or the usb port or whatever? so will it work for the m3,m8, ipod, and other mp3 players? Also it either uses batteries or you can charge it to a wall right. I saw this speaker at tj maxx for 8 bucks that uses a headphone jack and doesn't even use batteries. it takes the power from the mp3 player directly. and i was gonna buy it but i was thinking maybe i should just buy the one for the meizu.
