Summary: I bought this to connect an Apple Airport Express and TV to the same stereo (save time and hassle swapping out cables). It does the job but it is worth noting that, because of the lack of integrated amp, the signal will be quieter than via a direct connection. For the price though this is a great product.
Summary: To be fair I didn't use it that much, but the build quality is great and works perfectly. The sound is attenuated a bit when more headphones are in use, but that is expected, but other than that is handy enough to share music on a train/flight with somebody or simply for improvise a conference call :-)
Summary: First of all I feel it is important dispel some of the criticisms of this item from my own experience. I have tested this with 3 sets of headphone and 2 outputs. As other reviewers point out without any sound boosting element to the product sound loss is inevitable and such an item would be significantly more expensive if it did have sound boosting facilities.
