The first Beats by Dr. Dre headphones hit back in March to plenty of fanfare around the web.  Building on that success, Monster has announced Beats by Dr. Dre Tour In-Ear Headphones.  The Dre Tour earbuds feature 24k gold contacts for clear connectivity, a low-mass, wide bandwidth driver for a healthy bass response, a tangle-free cable and that little b dre logo.  Naturally, as earbuds they provide plenty of isolation to keep your ears on the tunes, not the worldly distractions around you.
