Through the recommendation of a colleague I bought this speaker for our notebook. Have now seen at Amazon, that You are the identical speakers also of Music? Which are all made in China anyway (it is well) and everyone does just his own stamp on it ... MicroSD I have not tried? In full Gass music or full volume of the speakers DVD jumps wildly, that is certainly not optimal soo? I bought it mainly to improve sound reproduction for my notebook. All in all a good value for money! Purchase is definitely recommended ...
