Our take on the Sennheiser/adidas® PMX 680

by Kristen Schaub

You won't have to worry about your headphones falling out during a tough workout with the PMX 680s. Designed by Sennheiser and adidas, they feature a rugged headband with an ergonomic behind-the-neck design that keeps the earbuds securely in place for running, lifting, and more. Kevlar® reinforced cabling plus a sweat- and water-resistant design ensure long-term durability. High-quality Sennheiser drivers and construction guarantee outstanding, high-energy sound.

The PMX 680s come with a built-in volume control that makes it easy adjust the sound without having to fumble with your player. If you wear your music player in an armband while exercising, the headphone's attached short cable is the perfect length to avoid getting tangled. If you need more cord length to put your player on a belt clip or in a pocket, just plug in the included extension cable and you're all set. A handy clothing clip helps keep the cord out of your way.

Great for running

Written By BryanD, West Chester, PA on Thursday, April 18, 2013

Crutchfield Customer Review (What's this?)

other earbuds kept falling out of my ears the second I started to sweat. These sit comfortably and don't move while running or sweating.

Pros:

Very light, comfortable, don't move while sweating.

Good equipment

Written By Dan, Ridgecrest, CA on Friday, February 03, 2012

Crutchfield Customer Review (What's this?)

These headphones work exactly as advertised. I use them with an arm band without the volume control. Go jogging about 7 miles and they stay in place the whole time. Very comfortable.

Pros:

Comfortable, stay put, good sound.

Cons:

Would prefer a different color (black), but not that important.

great with arm band

Written By Susan, MA on Monday, January 30, 2012

I have used these headphones for a couple of years with an armband. I used it with the short cord and they are quite comfortable. They are not in the ear so not at all noise cancelling.The ear piece sits sideways in the ear which never bothered me until i pressed it with my hands and realized what it should sound like. I recently got an iphone so tried to use these with the extender cord instead of the arm band. There are problems with the control hanging so it swings uncomfortably and I cannot seem to clip it unless i do so at an awkward place on my side/stomach as it doesn't reach my waist. Would be fine if you keep you phone/ipod in a pocket or on the arm but i found the cord to be a hindrance with the control location (if kept ahead on a workout machine).

Pros:

comfortable, flexible, washable, can opt to use a short cord

Cons:

could fit closer to ear to block more outside noise, volume control is at an awkward distance so it hangs and swings when moving

Crutchfield Customer Review (What's this?)

Great headphones. When laying a flat bench, you may want to tilt them a bit so
that they do not pop out of your ears. Highly recommend them.

Very nice

Written By Shane G, Marlton, NJ on Tuesday, January 04, 2011

Crutchfield Customer Review (What's this?)

Got these in today and the sound quality is great. I have a big head and these were still plenty big. In fact, it would be nice to have it fit a little more snug in the back. Very comfortable nonetheless. I'll give these a shot skiing this weekend.
