A lot of earphone and headphone manufacturers tend to tout their noise-isolation or noise-cancellation feature as one of its selling point, and while those features are great for listening to music uninterrupted by the outside world, they can be dangerous when walking on the street as they could prevent sounds of cars and other potential dangers. To combat that problem, audiologist Matt Murphy has since come up with the earHero, a pair of earphones that goes directly into the wearer's ear canal that's small enough to fit, but not big enough that it blocks the canal's width, thus allowing outside sounds to come through.
Ubergizmo, earHero earphones will go directly into your ear canal
