Our take on the Sennheiser/adidas® MX 680

by Kristen Schaub

Sennheiser and adidas worked together to create these lightweight, sporty headphones to help your workouts go more smoothly. Sennheiser's high-quality drivers produce clear sound with high-energy bass, and are housed in moisture-resistant earbud casings. The exclusive "EarFin" design keeps the earbuds comfortably and securely in place just inside your ear, even during a hard workout.

The MX 680s come with a range of ear sleeves and EarFin adapters to help ensure a comfortable fit. A control dial built into the headphone cord lets you adjust the volume of your tunes without having to fumble with your player. And a cable clip keeps the cord out of your way, while the carrying pouch stores your earbuds until your next workout.

    Abominable

    Written By maryte, Austin, TX on Wednesday, May 16, 2012
    Crutchfield Customer Review (What's this?)
     
    These are horrifying. I got them to use with my iPod while working out in the gym (elliptical, recumbent, treadmill) and 1) I cannot fit them in my ears (regardless of the cushion size used) without them falling out and 2) they are so large and hard that they cause distressing pain - and this has nothing to do with the volume of the music I play! The sound is probably adequate, but I can't really tell because they fit so badly. Worst money I have ever spent on headphones.
    Pros:
    None that I'm aware of
    Cons:
    Poor fit, painful design

    Crutchfield Customer Review (What's this?)
     
    Good sound quality. The variable earpieces take some fiddling with to find the
    right combination. My only real complaint would be that the main cord is too
    short. The extension with the volume control is too heavy, it causes the
    earpieces to become dislodged during a run. The clips aren't of much use in
    this area. I had to unplug the extension and clip my iPod shuffle to my collar
    during a recent 5K. Would prefer a lighter extension maybe without the volume
    control. Really like the sweat resistance of the earpieces - that's been an
    issue with other ear-buds. Overall, I'm satisfied. Good value and with a spiffy
    yellow color too!
