TaoTronics® Portable Bluetooth 4.0 Speaker, Micro SD Card Slot, Enhanced Bass Boost, Buit in Mic, USB PC Speaker, 8 Hours Playtime (TT-SK01 Black)
Pros: Small, Loud, Micro-SD, Sound quality is amazing, Price<br /><br />Cons: Not that great range, Bluetooth pairing is not reliable (I have to turn my phone's bluetooth off every time I want to use it after turning the speaker off)<br /><br />If this were $10-15 dollars more my rating wouldn't be as good, but for the price I don't mind having to constantly pair the device.
