Griffin Technology today announced SmartShare, a headphone/audio splitter designed with the iPod in mind. The accessory lets users share their music and videos with a friend. “Plug SmartShare into the mini-jack of any iPod, MP3, CD, portable DVD player or laptop computer and invite a friend to a party of two,” notes the announcement. “Since some partygoers like their music and soundtracks louder than others, Griffin has integrated a slim volume control slider into each of SmartShare’s output jacks.” The Griffin SmartShare is scheduled to begin shipping next month for US$19.99.
