Sennheiser MX 80 Sport II

The Sennheiser MX 80 Sport II are earbud-style earphones featuring Sennheiser's Basswind system that delivers a powerful bass response.  The earphones are sweat and water resistant and are washable under running water making it possible to use them during water activities.  The design of the earphones is both ergonomic for comfort and rugged for durability and they are very lightweight at only 6 grams.  They are optimized for most portable media devices and come with a cable clip and carrying pouch.  The difference between this model and Sennheiser's OMX 80 Sport II earphones are that these earphones fit in the ear like standard earbuds while the OMX 80 Sport II earphones have an earclip that goes over the ear to secure them in place.  This model is also completely different from the PMX 80 Sport II earphones with regards to the design and speaker system.
