The hooks are adjustable to fit just about every ear and they stay in place when I go running and that is a plus for me.

I had previously owned the Sennheiser CX 680 Earfin Sports Earbuds. I wrote a lengthy review of these earbuds, which is the "Most Helpful" review of this product on Amazon.com. I used my CX 680s several times a week at the gym and they performed well; they had a good run (so to speak). After about two years the plastic piece that connected one of the earbuds to its wire came loose, but it was easily fixed with superglue. About six months later, however, the sound gave out in one earbud, forcing me to trash them.

In hindsight, and in light of my recent purchase of the CX 685s, I would give the CX 680s 3 stars. The thing that bothered me the most about them was that with a lot of movement and sweating (e.g., running) the earfins sometimes became squishy and dislodged from my ear, thereby causing the earbud to come out. This was annoying and kind of defeated the purpose of these types of earbuds. By comparison, I will say that the PMX 70s (also reviewed) stayed in much better than the CX 680s during exercise. The downside to them for me was that they were the neckband type and were not noise-isolating. Those things and the sound starting to cut out due to issue with the wiring within several months of use (I just sent them to Sennheiser hoping they will repair or replace them) forced me to look for new earbuds.

Again I spent many hours searching for and reading reviews about earbuds designed to be noise-isolating and stay in place during activities like running. I narrowed my search to

Just got these headphones and am very satisfied. A few years ago I bought some sennheiser headphones (twist to fit, orange. Model no longer being made) and was very happy with the sound quality and fit during workout. The wire recently wore out after 3 + years of 3-4 times/week usage. The sound quality was great and they fit very well, never slipped during a workout (moving and slipping during workout was my main complaint before buying them). I had bought the CX 680 recently but sent it back, as the earfins did not hold them securely in my ear(plastic not hard enough to keep them in ear w sweat and moving).
These headphones have excellent sound quality across all music, from oldies to led zeppelin to new R&B(great bass). They fit well in the ear and stay there, as the plastic is firmer. The 3 size adjustments are also nice. They are in-ear models, so have a slightly different feel from most others that have foam-like padding on the headphones that sits outside the ear canal. These almost feel like having small earplugs in, which can be good or bad depending on your needs. They definitely block out more outside noise, so you don't hear the music at the gym that you don't want to. However, if you plan on using them to workout with a partner(or anywhere you want to have conversation while working out), you may have to take them out to hear somebody else talk. My old ones I could just pause my music and keep the headphones in, but these block out much more sound. This may also be dangerous if you use them jogging in an urban environment where you can't hear cars or people yelling. These are also water proof so you can rinse w water after your workout to keep them from getting buildup.
Overall, I think they're a great buy. I am loyal to this brand after my previous purchase, and will hopefully get good use out of these.

Vine Customer Review of Free Product ( What's this? )
If you run, finding headphones with the ideal mix of fit and sound-quality is always challenging. Based on the product description for these, I was hoping for the best of both worlds. Unfortunately, it only delivered one half of the equation for me.

These are "in-ear" headphones, which means you need to insert the bud into your ear canal. The package contains 3 interchangeable tips, so you'll need to find the one that fits your ear canal the best. You need to slightly twist them into your ear canal to seal them. Then, there's a second component to holding them in-place. The earbud has a flexible tip on an adjustable extention that you must fit into the ridge of your ear, just above your ear canal. Let's just say -- figuring out how to get this work will require some trial-and-error, and perhaps a mirror. Eventually you'll have "Eureka!" moment and you'll realize they are securely in your ear.

Continuing on comfort...when I have these positioned correctly in my ear, they initially feel good. They stay secure during a 30-minute run on a treadmill. There is a included clip that you can attach to the cable, and then attach to your shirt, to keep the cable from banging around on your chest, which minimizes any vibration and tugging on the earbuds in your ears. When it comes to keeping these "in the ear", the design works incredible well.

However, I don't recommend wearing them for extended periods of time because -- at least for me -- they get extremely uncomfortable. Not only are they "in your ear", but the added flexible tip ends up pushing up against the ridge of your ear with a bit of pressure. After about two hours of use, I have to stop using them. This doesn't make them good for all-around, every day use.
