Here is a little something to help all those whose New Year resolution was to begin making the commitment of going to the gym.  There are tons of people i know, including myself, that just can't deal with ear-buds.  Constantly having to worry about not moving your head in certain directions.  Trying to snatch them up before they hit the floor and stepping on them.  All sorts of crazy irritations that make us use and need headphones.  The Sennheiser CX 680 aims to solve that problem and also give you tons more.

The CX 680 are sweat-proof, water resistant (give them a rinse after workouts), noise-isolating, and Sanheiser say's can "block out up to 20 dB of gym noise".  I'm not sure about that until I give them a whirl at a gym but I can sure tell you that the "EarFin" which is a rubber fin shaped object that is attached to the earbud sure does the job and keep them in place. Also, come with a volume adjuster to control your tunes and a detachable extension cable that lets you position your MP3 player where you want it and not have to worry about having a very long cable dangling around.

With Kevlar reinforced cabling you are sure they will give you the durability you are looking for in a sport ear-buds.
