A while back we reported on a set of concept headphones that would allow users to plug into each other headphones and share the music. It is a pretty good idea, but the bad news is that it is only a concept device, which means we may never actually see it hit mass production. However, if sharing music with friends and loved ones is your thing, perhaps Kikkerland's branching headphone splitters might be right up your alley. Typically headphone splitters only allow splitting up to two ways, which could prove to be an awkward situation if there are three of you, which means one person could potentially be left out.
