I just bought some of these Hearos expanding foam ear plugs (via Slate) to drown out the background noise at work, and simply put, they're heavenly.  As soon as one of my co-workers starts talking too close to my circle of self-imposed sensory deprivation, I just pop in these ear plugs and listen to what I would assume to be blood flowing through my brain.  But the best part is the 30 or so seconds it takes for the foam to fully expand, as all the various noises, bodily functions, and mind-numbingly stupid conversations disappear into thin air.  It's magical. #products
