<\/a><\/p>\nWe found a pair of these previously announced<\/a> Sennheiser headphones here at CES and got a hands-on demo for you guys.<\/p>\n 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.<\/p>\n There are four models in the series.<\/a> All have a reported frequency response of 18Hz – 20kHz, maximum output of 120 dB (save the MX which peaks at 118 dB), and 16 \u2126’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.<\/p>\n 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.<\/p>\n<\/a>The difference in the models are in the design styles. The OMX are pictured above, and go over your ears. I wasn’t able to get a good fit with them, due to my glasses. The MX and CX in-ears are shown to the left, with only the CX actually going into your ear-canal. The “ear-fin” secures the earbuds against the inside of your ear. It works, but it’s not the most comfortable configuration. The PMX, below, is a neckband design, and in my opinion, the most secure fitting and comfortable of all four.<\/p>\n<\/a><\/p>\n
