Earbud style headphones let you enjoy your music without the distraction of what's going on around you. But for safety's sake sometimes hearing distractions, like a honking horn, isn't a bad thing. So the earHeros use a compact design that doesn't completely block your ears.
Each tiny speaker sits inside your ear canal, using a small wire extending into your outer ear to keep them in place. And because they're not crammed in there like a cork, other sounds can still be heard. The earHeros supposedly sound as good as a regular pair of earbuds, but also allow you to still hear conversations when they're being worn, or even talk on a phone.
They're particularly ideal for those who like to ride a bike and enjoy their music without being hit by a car. But the $150 earHero's subtle design means you can probably also get away with wearing them during boring college lectures, or long meetings with your boss about how you're always distracted.
