It is usable both RCA (red / white connectors) that audio jack, thanks to an ingenious reversible system. Note that the product is very small, which is a definite plus.
However attention to a few small cable, which does not bother me though, since everything is well suited for the setup I have. The (mighty) LED light operation is sometimes annoying (beware if you sleep in the same room as the box ...).
Used with a MacBook Pro, an iPhone 5 and 5C, and a iPad, still very simply!
