Sennheiser MX 680

Sennheiser MX 680 Sports Earbud Headphone

Sennheiser MX 680 Sports is an in-canal earphone pair, which means better bass response and a more secure fit than earbuds. Innovative design features help the earpieces stay in place during intense workouts while waterproof materials say you can sweat on the earphones or even rinse them off.

Design

The sporty black earpieces stand in stark contrast to the neon-yellow Kevlar cable and earpads on the lightweight Sennheiser MX 680. The earpieces, along with the cable, are constructed from a highly durable material, which is resistant to both water and perspiration. A flexible rubber fin juts upward, away from the earpiece like a small horn providing a secure fit. The two earpieces’ cables become one inside a tiny piece of rubbery plastic that features the Sennheiser logo on one side and the Adidas logo on the other. Further down the approximately 2-foot-long cable, there’s an in-line volume control, which is much easier to access and operate than the physical volume buttons on most players or the on-screen slide on an iPod touch.

SENNHEISER/ADIDAS PERFORMANCE

Engineered on legendary Sennheiser/Adidas Performance, the Sennheiser MX680 sports headphones deliver the best of both worlds, producing energizing, high-output that keeps you running. Get great audio feedback of your workout with the Sennheiser MX680 and the Adidas miCoach. These headphones are also compatible with iPhone and all iPods/MP3 players with a 1/8″ (3.5mm) plug.

Conclusion

The Sennheiser/Adidas MX 680i Sports Earbuds are ideal for running/exercising/working out. They produce a much better listening experience than the stock earbuds Apple includes with their iDevices. The 680i-series are durable, water/sweat-resistant, and give you a much richer base and upper-end sound quality.
