Review on Enhanced Portable Bluetooth Stereo Speaker with Dual 5W Drivers, FM Radio, Handsfree Speakerphone, 🔊 Micro SD Card & USB & AUX Slots for Smart Phone, MP3, iPad, Tablet & More by Darius Early

Have fun with this little speaker. Wear it wherever we sit and want some music. It's nice that this requires a USB drive, although getting the speaker to recognize the drive is a little tricky. Four stars because the voice prompt is very annoying every time you turn it on. After I posted the four star review above, the seller contacted me and offered to send me an updated firmware that would remove the annoying ads. He immediately sent the new firmware. A little fiddling got the correct firmware and updated the speaker. This works very well now. Excellent supplier support.
