Have you tried to follow the train or sit with a friend in the back seat of the car and wish you could share music? Yes, you can just have an earpod in your ear each, but what if you prefer to wear a proper set of headphones for the long trip? This is where the mini jack splitter comes in.

With it, you can share your music with a friend, each of you with your own set of headphones! Or you can set your music to two sets of speakers. There are probably other useful options with those that we have not yet thought of.

The adapter is very simple: It has a mini jack end you put in your smartphone or computer, or whatever other device the music comes from, and then there's a splitter part with two mini jack inputs. This is where the two sets of headphones are inserted, and you're ready! It works right away.
