Do not buy this product! Sound is good; HOWEVER, half the voice prompts are not English. Voice commands are not recognised in English. The AUX does not work. The sound WILL be roughly 2.5seconds behind any video your watching. You CANNOT connect to more than one iDevice at the same time. You CANNOT stream radio (Radio1/1xtra) via WiFi whilst connected through Bluetooth as it continuously makes the WiFi drop out. The instruction booklet is pointless, half the sequences it instructs you to do are the reverse of what you actually need to do, and in some modes it says volume controls don't work - they actually do, and vise-versa. You cannot charge the device whilst using it or you get very bad distortion. This speaker is not a good purchase - unless you highly dislike the person you are getting it from. Have been through a few different mini/Bluetooth speakers, and this is the worse one I've ever seen... DO NOT BUY THIS PRODUCT!!
