Designed with help from adidas, the Sennheiser PMX 680i is a set of headphones geared toward use with the iPod and iPhone. The integrated remote allows you to control tracks. There is also an omni-directional microphone integrated into this headset, which allows you to handle phone calls. As far as the fit of these headphones goes, the ergonomic neckband keeps them securely on your head, even during an intense workout. The around-the-head design of these headphones is what differentiates them from the identically priced MX 680i (which are in-ear) and OMX 680i (which are around-the-ear) models. In case you are working out outdoors, these headphones are water resistant, in addition to being sweat resistant.
