Sennheiser CX 685 Adidas Sports In-Ear Headphones

Better Fins: An Improvement on the CX 680s - UPDATE
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...

Great headphones
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...

secure fit, just-OK sound quality
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...
