Griffin Technology today announced the Griffin EarJams, which snap on to an iPod’s existing earbud-style headphones to increase the bass output, volume level and comfort. The company says a sonic enhancing cone extends the sound directly into the ear and is protected and made comfortable by slip-on soft ear pads. Three sizes of removable pads are included for an individual fit. In addition, the package includes a small canvas carrying case. The new Griffin EarJams will be shown next week at Apple Expo Paris and will ship in September for US$19.99.
