The Sennheiser Adidas CX 680 Sports Headset is one of the first pair of workout headphones to utilize an ear fin technology to secure the earbuds during activity. This new technology combined with Sennheiser’s quality build of headphones makes these perfect for any one.
Sweat Resistant. While a lot of sports headphones claim to be sweat resistant, these stand up to just about any test.
Cable Length Options. Either use the shorter cable with an armband or switch to the longer cable with inline controls. Both work great.
Ear Fins. These are less intrusive than over ear hooks or having to jam the ear buds deep in your ear canal, and work better.
Ear Fins. We know we listed this as a pro, but the thing is most people aren’t used to this type of fit and end up finding it somewhat awkward. Though we still think they’re amazing.
If you’re tired of in-ear canal earbuds that make you feel like you have to spend 3 minutes jamming them into your ear just to get a great fit then the Sennheiser CX 680 may be the perfect fit for you. We really love the new ear fin technology that utilizes a soft silicone fin to rest just inside the ear. They pass just about every secure fit test we can think of.
In addition they are sweat resistant and noise isolating. While the noise isolation isn’t up to the standards of Ultimate Ears or Shure, they are pretty impressive for workout headphones, and it definitely makes a difference at the gym.
