Portable speakers SHARKK

micro SD, Bluetooth, 6h, Silver Okay, so I am absolutely amazed at this little speaker! It has great sound, connects to bluetooth Ipod/Ipad quickly, plugs into my ipod without bluetooth, and even works well with a micro SD card. The buttons are pretty small, but once I got used to them I had no problem using them correctly. I love that I can put a micro SD card in it and it is even more portable. I had a bit of difficulty getting the SD card in, as one must push the card all the way in until it clicks in place. I had to use a pen point to get it to release the card. Now that I know that, it's no problem at all! I charged the battery via USB when It arrived, and have been playing it now for at least 6 hours without needing to recharge. The battery life seems impressive, and I'll keep using it until I notice the battery dropping off. I like, too, that it has one cord which works to charge via USB, and also connects to the auxiliary device (ipod without bluetooth. ) so I only need to carry one cord. It even comes with a bag for carrying. I have spent up to 70 dollars for portable speakers, and this one sounds just as good, and has more capabilities.
