Do they exist? - Jogging/biking earphones that allow you to hear outside sounds?
We all know that shutting out noise with headphones is not safe if you are driving, jogging, biking or sitting with your sig other when she has something to say. But suppose you want to listen to music or an audiobook safely.
Is there any product that allows you to listen while still hearing the outside world? Something that is not unlike turning on a stereo in a room at a reasonable volume -- you hear the music but you also hear the room. But which won't be too disturbing to others near you.
One thought is headphones/earphones that hang just below the ear so they don't block sound. But all the ones I know about that can be adjusted that way, either don't stay in place or are really bad sound from even a short distance from the ear.
Anyone know of such a product?
