      I am a big Sennheiser fan so when they teamed up with Adidas I knew these headphones would be a winner! I was SO right. The sound quality is remarkable. Not only do you hear crisp highs but you also hear a good low end too. That was not what I was expecting. During my workouts the PMX680's stayed in place while doing my aerobic workout on the treadmill, the elliptical, the bike and the recombant bike and the stepper. No problem with needing to adjust them. The volume control on the wire is a must and I'm glad its there. I've used behind-the-neck headphones in the past but these are by far the best I've ever had.

      Why did Sennheiser Make those Hedaphone?

      I have owned 4 pair of Sennheiser behind the head headphone. 1 Sennheiser PMX70, 3 Sennheiser PMX80 and now this pair Sennheiser PMX680 and I have used the PMX680 for a few months now.

      The reason why I have had so many headphones is because the cord connecting to the phone jack keeps breaking. Very annoying however I really do enjoy the sound quality so I keep buying them. I also need to state that I always keep my mp3 player/iPhone in my pocket. So for that reason this can contribute to the short life span of my headphones. I just needed to state that!

      The flaws on the PMX680 are as followed...
      1. The Headphones are slightly heavier than the previous models PMX70/80.

      2. To get the best sound quality when wearing the headphones you need to have the headphones in a up position. Think of having the headphones resting on you neck, that would be the down position. You need to have them way up to hear the sound better. conclusion... they were designed a bit strange?

      3 How do they compare to the previously models? Not too sure... the sound is definitely different, however it almost sounds like better treble and not base? If you move the headphones to a higher position then I would say yes they do sound... crisper and I can hear the base, but the headphones never stay in that position.

      4. The speakers are a tad bit bigger. The rubber piece feels much much more comfortable compared to the previous models, however if you have small ears like me then the PMX680 do tend to feel bigger.

      5. The volume control is a bit heavy, cumbersome, annoying. I'll explain. If I decided to jog, not run across the street. The volume controller starts bouncing up and down on my chest/"a bit heavy". The position which the headband needs to be in to get better sound which is up, starts slowing bouncing down due to the weight of the volume controller"cumbersome". By the time I am on the other side of the street, I am"ANNOYED!!!"

      6. Like the previous models headphones, the cord by the phonejack is loose/broken again!

      7.If you are a jogger I would think that these headphones would be your worst nightmare with the volume controller constantly bouncing around unless you hold it in your hand. I am not a jogger however I am a ballroom dance and I find that the weight of the headphones and the constant pull from the volume controller to be EXTREMELY ANNOYING to the point where I don't even use them anymore to dance with.

      8. Conclusion. I think these are the WORST design headphones I have every bought. Sorry Sennheiser, I really like you guys however the PMX680 do BLOW! And this is my 5 pair of behind the neck headphones, I DO HAVE EXPERIENCE WEARING AND USING SENNHEISER HEADPHONES THROUGH THE YEARS!

      Sennheiser, please drop that annoying volume controller and go back to the PMX70/80 design.

      I now need a new pair of headphones. I'm on my way to another website to find a pair of PMX80 because they are better in my experience.

      Hope this helps and sorry for the long review/rant!

                  Not bad sound but a bit bass heavy. However, not at the expense of mids and treble. Fit is ok but not great. Angle of earbuds is off a bit imo, but everyone's head will be different. I use them without the cord extension that includes volume control. Cord is long enough to reach my android when it's on an armband.

                      These are so good I ordered a 2nd pair. I keep one with my EOS C300 because the monitor output requires a low impedance headset. These are perfect for checking sound on-the-run. The other pair is for hiking. They're super-comfortable, have plenty of volume, stay in place and are sweat-proof. As I write, it's difficult resisting a third pair.

                        This is my second pair of these headphones. The first lasted 2 1/2 years and they developed a short. I replaced them with the same model because of the sound quality, comfort and volume control. I didn't want the newer model that has a microphone, as these I use solely for running. These held up well, some of the screws got rusty after 2 years of sweat, but that's a minor blemish. Very comfortable and they hold my glasses in place so they don't slip or bounce around. The only reason they don't get 5 stars is the volume control part gave out after a year, but that part is detachable.

                                I use these headphones mostly for running and find them to be very comfortable (cord aside) with decent sound. I'd give them a 4 or 5 star rating if it weren't for cord design. The shorter cord would be nice if I wore my music player on my arm, but I don't so I have to use the extension with the obnoxious volume control. Given the location of the control I can see no good reason for it to be there. As is I have it wrapped in tape to avoid accidentally adjusting the volume while running. I've always run with my headphones cord under my shirt so the bouncing isn't a problem for me as it is for others. My suggestion would be to keep the extension concept, but either completely remove the volume control module from this product or at least make it removable by the user.The three star review would be lowered further if the price were higher, but for the $[$]I paid I'm more happy than not so three stars it is.

                                      I've owned a pair for nearly a year and just bought another pair for my wife. Perfect for running. These do not move unlike isolation headphones. Sound is very good compared to expensive pair of Monster iSport Livestrong headphones. Bass a bit weaker and treble a bit brighter, but overall very good. highly recommend at current sales price.

                                      If you're looking for sweat-proof headphones strictly for running, then you've come to the right place. If you need headphones that you can use in and out of the gym, then I advise to keep looking. Sound wise, they're good, extremely loud with satisfactory bass and treble. Out of the gym, I truly found these headphones awkward and uncomfortable. You can't lay on your back with them-or side for that matter. It also interferes with anything behind your head. For instance, if you're sitting in a chair or wearing a hoodie or jacket, the band always snags something and it's quite irritating actually. Also, Sennheiser used to be known for making high-end products, but the plastic used for these headphones/volume switch is so embarrassingly low-quality that I'm questioning ever buying anything from them again. Overall, I'm not a huge fan of these headphones, they're good for running, but otherwise I feel like a cat wearing mittens-I don't know what to do, how do i move, somethings not right, help. Oh yeah, and if you do buy them, make sure you get them on sale. I could never justify buying these for anything more than $25 bucks...especially with that cheap plastic, yikes, what were they thinking with that one. Hope that helps. Thanks.

                                      I purchased these headphones for working out. Overall the sound quality is decent and much better than your average in the ear headphones. The bass is particularly good while the table and higher sounds could be a bit more prominent. The fit ion my head is good but did take some getting used to for me especially when weight training. The plastic band around the back of the head can be uncomfortable when laying down to do exercises. The volume control is handy at times but is a bit large and weighs a lot. Overall I would only recommend these headphones for runners and upright exercises.

                                              I bought this as a replacement as my daughter damaged my first one. I love it because it fits nicely in my ear and around the back of my head. I walk a lot to exercise and it is light enough to wear and does't fall off easily… it also provide good sound as I play music through my iPhone. The microphone picks up my voice clearly too if I have to pick up a call with little noise pickup from the surrounding.

                                                  These headphones work great for running. They stay in place, don't bounce out, and don't hurt my ears. The wire is out of the way too when plugged into my pho e in my pocket.

                                                        Used this for almost a week every morning for my short daily running. I used to wear $15 light headphone for running but it broke within a year and was looking for something that last longer. Although this headphone stays on head very well, it gave me ear/head ache couple time. Sounds clear but there is no bass at all. I love bass sound especially when I'm running so it is quite a bummer for me. If it continues to give me a headache I am thinking of returning it. As for extension, I am not planning on using them even if I decide to keep it.
