Babypod was conceived after a study by Institut Marquès demonstrated that fetuses can hear and react to sounds at 16 weeks. It's still up for debate whether babies in utero actually benefit from listening to your smartphone playlist, though Babypod claims its device "stimulates the vocalization of babies before birth through music and encourages their neural development." It may also encourage grooving and shaking, though that's just a guess.

Around Christmas, singer Soraya Arnelas performed for an audience of pregnant women using Babypods. There's no word on whether she sang "Baby, it's Cold Outside."
