Style Name:Microphone
I train for two full marathons per year, and I sweated my way through two sets of ear buds in less than a year, so I was looking for replacements that were specifically designed for the rigors of serious running. I quickly found the Sennheiser/Addidas branded models online. I chose the MX680 "ear fin" models, as I did not want a behind-the-neck band flopping around while I run, and I did not want the isolation of a traditional sealed ear canal ear bud, since I prefer to hear cars before I am under them.

The MX680 is very close to perfect for this combination of criteria. The ear fins feel strange at first, mostly because it feels like they cannot possibly stay in place, but they do, and they are comfortable. They're so light I can hardly feel that they're there, and I can hear ambient noise, so the overall design works as advertised. And there are plenty of sizes of fins and ear cushions included to fit every size and shape. The MX680 does not produce the thunderous bass of expensive, tightly sealed ear buds, but overall sound quality is very good, including decent bass (much better, for example, than the tinny sound that results when sealed ear buds slip loose in the ear). And the open air sound is great for running outdoors.

I purchased the iPhone compatible MX680i, hoping that at least the mic would work for phone calls with my Motorola Droid. It doesn't. The remote partially works with the Droid, allowing me to pause or advance tracks, but volume and mic do not work. I knew I was taking a risk that this would turn out to be the case, but for others trying to choose between the MX680 and the MX680i, don't spend the extra money if you are not going to use it with an iPhone. The MX680i **will** work as ordinary headphones on any 1/8" stereo jack, though. In addition to dozens of miles of all weather outdoor running so far in the three weeks I have had these, I have also been happy using these on hotel treadmills and on my notebook computer when I did not want the isolation of my more expensive ear buds.

Style Name:Microphone
I've owned my pair for more than 3 months now and have been extremely satisfied with them.

Sweat-proofing: This was the major selling point for me as I have gone through half a dozen other Apple-chip-enabled earphones that I have sweated to death. After 3 months I feel like this pair will go the distance. The rubber controls and microphone (all in the same unit) appear to be well protected and robust. Don't take these for a swim, but feel free to wear them in a sweat box or during a particularly hot and passionate night.

Sound Quality: This attribute is not a high priority for me, but they sound good. Certainly acceptable for my gym-centered purposes.

Sound Isolation: These earphones are designed to leak outside sound in so that you can remain aware while running or cycling in them. Do not make the mistake of thinking they would be good to wear on an airplane or in your office. Your neighbor will hear what you're listening to pretty easily. If you're looking to keep your self help audiobook collection a secret, then look elsewhere.

Microphone: Audio from the microphone is great. I've used it a few times during conference calls for work and they produce as clear audio as my Scosche earbuds of much higher cost. Using these you can feel confident that you're calls to those 900 number businesses won't be wasted (or will be, if that's what you're in to).

Fit and Finish: The earphones come with many rubberized parts of various sizes so you'll be able to squeeze these things into your elfish or octogenarian ears. The arching rubber seen in the product picture above the earbud itself is made of a very soft/pliable material (there are 3 sizes of this and it is optional if you don't like it). The arch is meant to fit into the upper crevices of your ear to help retain the earbud in your ear hole. Mission accomplished through an rough trail running or aggressive actions between the sheets.

The remote itself: I'd take away half a star here if I could. The buttons are squishy and don't have a solid click or feedback to reinforce that it has been pushed. Additionally, the 3 buttons are molded into a single rubberized set of buttons, meaning there is no *physical* separation of the buttons. The combination of these two things (one-button-to-rule-them-all and no feedback) means that using the buttons while wearing gloves in the cold weather is a guessing game. This issue is not a problem when your hands are unprotected.

Plug: It looks like it could take more abuse than a pro in the Amsterdam red light district. Don't fear sticking it in and out of your iPhone/iPod.

Great for working out. March 6, 2010
Style Name:Standard|Amazon Verified Purchase
I have to admit that I was dubious of these when I first saw them. Ear fins do not seem like they would be comfortable, and I could see how it would be a problem. At first it was a little strange, but after using them for a while I do not even notice the fins anymore. The sound is good for ear buds that are only used to work out, and I actually use them just walking around. The bright yellow is a little intense for my tastes, but nobody really seems to notice unless I point it out. These work great for what they were intended for. The extension cable does not degrade the sound enough to matter at all, I actually did not notice any degradation, and since I do not own a iPod Shuffle, some of the reported problems with that system (which seem like a design flaw that that product more that this one) do not exist for me. Very happy with this purchase overall. It should be noted that those who are worried about different size ears should be able to find something close to their size in the pile of extras that come with this ear bud set.

The downside would be that they are not as high performing as some of the other Sennheiser audio listening devices. This is not all that surprising considering they are not designed for in depth listening but being active, and in that they excel. Even jumping around for four hours strait and slinging heavy boxes around does not move these out of place.

Bottom line: Highly recommend for working out, but if you want to sit and listen to music I would suggest a different model.

Firstly, I didn't like the color! After trying them on, they were okay, and stayed in my ear even when I shook my head around. Read more

Still it falls off once in a while and it's tricky to adjust. I jog with those and it's frustrating to find the sweet spot every run I do.
