If you're going to make fitness-friendly tech, teaming up with an athletic company is a good way to go. At least Sennheiser thinks so. The headphone manufacturer elected to work with Adidas when updating its sport line of earphones.
The line includes four new models--the MX 680, the CX 680, the OMX 680, and the PMX 680--ranging in design and price. For more details on each, check out the slide show, but the most compelling info is the fact that the headphones are super sweat and water resistant. Expect to see them on the virtual marketplace later this month.
