5.0 out of 5 stars Great for working out. March 6, 2010

By C. Loporchio

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.

2.0 out of 5 stars Not a good replacement for MX75 April 14, 2011

By S. Pretti

The MX680s sound OK, but the volume control is a real deal killer. The clip on the volume control is worthless so the volume control ends up swinging around and eventually pulls the ear buds out of your ear. You can unplug the volume control, but that leaves you with a cord that is too short if you are wearing your player on your waist or in a pocket. So the headphones would be great without the volume control, but that option is not available. I'm looking for a new replacement now.

Sennheiser sent me these as a warranty replacement for my MX75s. I loved the MX75s, but they eventually corroded to the point where one ear bud wasn't working.

3.0 out of 5 stars Overpriced. March 25, 2010

By R. Ding

Pro: Flashy/sporty design. Lifetime warranty. Sweaty resistant.

Cons: Earfin is a bad take on Sennheiser's original "Twist-to-fit" system. Soundquality is quite terrible.

------------------

First of, these headphones look GOOD. The bright yellow and black color scheme is sexy. The build quality is quite good. Very nice attention to little details like the logo of "Sennheiser" on one side of the cable splitter and "Adiddas" on the other.

The MX 680 come with many accessories, different sizes of the earfins and the rubber around the earbuds. Foam socks. And the thick and rugged carrying case.

I own the MX75 (1st generation of Senn's sport line). I liked the original "twist to fit" system much better, because instead of a sharp "fin", they used round little wheels that roll much nicer against your ears and does not poke.

The earfins is very soft and at times does not offer enough stiffness to keep the buds in my ears. When they do, they hurt my ears after just a few minutes (and is distracting)

The cable system is quite bad. You may ditch the volume control and just connect to an armband. The problem is, the cable is not long enough when I move my arms running. But if I use the extender with volume control, it is very heavy and adds unwelcome tension to my ears.

Sennheiser does give you a clip that you can attach to the cable to keep it from dangling around. THat is totally useless to me because I work out in t-shirts (and I don't know anyone who does not) , there is absolutely no place for it to clip on.

SOUNDQUALITY - Okay, these headphones sound TINY and THIN. If you pushed them a bit into your ears they sound fantastic, but that is not feasible while lifting weights, on a bike, or running. So, if you leave them on like normal, they sound no better than stock earbuds that you get from buying any mp3 player.

There is literally no base thump. You can hear the beat, but there is no impact. One way to look at this is that music sounds extremely light, and will not become too involving or distracting from your workout. But without any low and mid-low end to balance out the frequencies, the highs just are shrieky. It will sound like your brain is being scraped.

Other companies offer headphones at much better values both above and below the price for the MX680, with better comfort and better soundquality. There is no reason to pay so much money for these to replace your stock buds. Except maybe for the looks, but then you should look to other products of the sports range.
