Sennheiser Adidas PMX 680 'neckband' headphones have a nifty vertical transducer speaker system and secure headband fit that won't fall out or come loose during your most active get-after-it workouts. Further, the PMX 680 headphone has an easy-fit neckband design suitable for nearly any head size -- a wonderful but rare plus in this category. The PMX 680 excellent ergonomics ensure long-term comfort without sacrificing wearing stability or impacting sound quality as you actively move about. A volume adjuster keeps you in handy control of your tunes and a (detachable) extension cable allows positioning your player wherever you need it. The tough Kevlar-reinforced cabling guarantees durability and flexibility where most other sport headphones simply can't function properly -- like here in our extra-cold Montana temperatures.

The Sennheiser adidas PMX 680 is amongst HeadRoom's biggest-selling exercise headphones, thanks in part to a terrific accessories fit-kit making the PMX680 a complete user-ready package. The Sennheiser packaging box includes extra sets of replaceable earpads, a useful travel/storage pouch along with a handy cable shirt clip for minimizing cord slack when you're moving.

Great for a while, beginning to die out like all others
Posted by ADEP from Boston, MA on 2012-05-30

Recommend Product: No
Pros: Sound, Fit, stays in place
Cons: Durability, comfort, Volume control

I was excited when I first got these. I thought: Finally, I'll have a pair of headphones that will last. 10 months later, I'm back to the place I've been to many times before, shopping online for a pair of headphones that will last over a year. Don't get me wrong, these were great for a while, but I definitely overlooked some flaws in hopes that these headphones would last forever.

First is the stupidly placed volume control that when removed leaves you with a one foot cord that can only be plugged into an arm strap. When trying to workout with this you have to clip it awkwardly onto the neck of your shirt if you don't want it flopping around.

Second, is the comfort of the earpiece. The yellow rubber around the ears fell off after about two weeks and now I can't wear the headphones for more than a couple hours without my ear throbbing.

Lastly, and most importantly is the quality. After 10 months they have begun shorting out. At this point I will gladly pay hundreds of dollars for headphones with some sort of long term guarantee. For now, I sit and dream of the day when I can own headphones for more than a year without them quitting on me.

Any suggestions of headphones that are more durable are welcome

Good but not great.

Recommend Product: No
Pros: Behind head Decent sound
Cons: not sturdy, uncomfortable

I bought these to fit below my climbing helmet for long approaches with large loads (they do this but a little uncomfortable particularly under a hood), I had been running the old PX200 and really loved there sound. For some reason these just don't come close to the sound of the PX200 (sorry no numbers, just subjective feelings). Lets get to my real issue. Look at the Picture of these. See the yellow ear-buds, these have two bands of unglued rubber built in that rotate on them selves and at worst rub off into your ear. I have had to rebuild this rubber bit on the "buds" more and more as they get older.They still work but are only 10 months old. OK enough bad. The sound is "OK" and they do sit behind your neck. Possibly there best function is the controller on the one sided cord. I fell for these, but will get a better sounding headphone that is not intended for sports next time. I think the "sports" category is asking for a downgrade that looks cool.
