Hands-on Sennheiser/Adidas 680 sports headphones
We found a pair of these previously announced Sennheiser headphones here at CES and got a hands-on demo for you guys.
The short version: They have a rugged, solid feel and great sound quality. A bit pricey, but if you are an avid outdoorsman, you won’t go wrong with these.
There are four models in the series. All have a reported frequency response of 18Hz – 20kHz, maximum output of 120 dB (save the MX which peaks at 118 dB), and 16 Ω’s of impedance. The kevlar-reinforced cable is a bit short, which cuts down on the amount of bounce while you’re running. You can add a cable extension if you want, which also gives you an in-line remote with volume control and a shirt clip. The headphones can supposedly withstand temperatures of up to (or down to, in this case) -10 degrees Centigrade. Unfortunately, no one at CES was showcasing a super walk-in freezer, so I wasn’t able to give these headphones a proper test. Nor was there a sauna company, so their sweat-proof claim is untested as well.
The audio quality across all four is great all around. If you jog often, and utilize your media player while you do so, these headphones are a good investment. Provided you have the 80 to 120 bucks for them.
