Sennheiser has been rather active with their partner in crime Adidas, as they’ve yet again launched four new headsets from their Sennheiser-Adidas sports headset lineup. The four members from the Sennheiser boy band is the Sennheiser CX 680i (Kernel Type), MX 680i (Open Type), OMX 680i (Earring Type) and PMX 680i (Neck Band Type).

For obvious reasons, these headsets are compatible with Apple’s iPhone and provide strong and dynamic sound quality when listening music as well as clean voice quality when calling. What’s more, the Sennheiser Sports Headset 680i series also adopts the waterproof system that protects internal components from sweat and waterdrop. Even the cables are of durable materials to endure the tough environments that you might be in. Who knows if you jog your way to Mount Everest every morning?
