Looking for suggestions on portable bluetooth speaker with usb or sd card slot for input. I'm getting this for someone in a remote place where the phone reception is not great. My last option is to use mobile via bluetooth but would be great if I can get a decent one with usb or sd card slot. Price wise I want some entry to mid range which is not a crap.
Whats your budget? You might find that a better option is to actually buy just a decent set of speakers (Edifier R1855DB etc depending on your budget, currently $220 at Amazon)
And then pick yourself up a basic media player, or make something from a raspberry pi etc
