I have bought the Logitech speakers nearly 2 month ago. and I should recommend it to all of you audio lovers. please if u really want a speaker that is made for value for money and it is full of special feature like clear sound and absolutely neat design and very strong. the attachment is very good and I have no problem with them. they are working super smooth and totally compatible with anything which has usb and audio port. I know there are other brand and low cost speaker so many people will go to them but listen cheap and best are two different thing if u go for cheap u will loose best .trust me I have used other brand and they are crap. so sad my money got wasted thats why I have purchased new one and thanks god I choose logitech . just loved using them daily. dont think about other option since it will confuse you most . just get logitech
