If you've ever seen a DJ on stage, you've no doubt seen them do that thing where the listen to only one side of their headphones to cue up a song. Numark just cut its Red Wave headphones in half to make this fun headphone stick specifically designed for this purpose.
The $US70 Numark Redphone has a single 50mm driver you can use to cue up jams on stage. It also has an ergonomic curved design so you can hold it to your shoulder like a telephone. Get it? Redphone. Like Batman. DJ to the rescue. [Numark via MusicRadar]
