So you don't HAVE to listen to LL Cool J while wearing these, but we're just sayin'. Maybe use these Spock-ear earbuds to jam to some Vulcan lute or take a call. Or perhaps their inspiration will help you tap into some of that Vulcan cool when you're on the phone with your cable company (if you still have one of those... ours brings us the Interwebs). They come with 3 sizes of silicone eartips, and you can use them for 4-5 hours on a single charge (depending on the volume). We're going to wear ours when we go running, because watching people do a double-take is fun.

These are going to be big among the cosplayers, that’s for sure.

That said, for $40, I don’t expect them to be that great.
