The idea behind the design of these headphones is great as they are almost invisible and can make you look like a member of the secret service. They are called earHero and you can include them in the category of open-ear headphones.
I personally don’t like stuff in my ears, so I prefer over-ear headphones, but I like these because they are lightweight so small that probably you can’t feel them.
The earHero earhones are designed by an audiologist and feature the standard 3.5mm audio jack to connect to your phone. They don’t produce special audio effects but you can hear the world around you while listening to the music anywhere you want.
You can buy these from ThinkGeek.com for $149.99.
