Sennheiser in-ear sport headphones 
2008-07-22
I love these sport headphones; once they are in, they don't move; very secure and the sound clarity is very good; the color is great too!! Great features and easy to fit. I'm very happy with this product.
Great for workouts 2008-07-21
I purchased these headphones specifically to use while working out. They did take a little getting used to at first, to get the right fit, but now they only take a few seconds to put in. I'm very happy with the sound quality and the way they stay in my ears even during rigorous activity. I really like the fact that they don't fall out of even move when I'm wiping my face with a towel. They do tend to hurt my ears after wearing them for over an hour, so I wouldn't recommend wearing them for very long periods of time. I do think these headphones will fit everyone differently, as people's ear shapes can vary. I have all of the smallest attachments on and they are still a little bit too big for me.
To address a few complaints that I have seen in other reviews:
1) The lengthy and 'twisty' cord - I use them with my iPod shuffle and find it very easy to leave the cord wrapped up (similar to the picture) and clip it into the iPod's clip.
2) The different lengths of the left and right headphone cord - This is by design. The right cord should be wrapped around over the left shoulder and behind the neck. This is so you only have one cord hanging in front of you.
I've been using these headphones everyday for a month now and overall I am very happy with them.
good sound bad cord 
2008-07-21
I bought this to replace one of their earphone sets I really liked. This has good sound, but the cord is to long and it is coiled. Every time I take it out to put it on I have to spend time to unravel all the knots. The previous style of earphones worked really well, but they don't sell it anymore. They should go back to the styles that work.
pretty much perfect

this is the 6th set of earbuds i've purchased for the ipod.
finally, buds that stay put in my ears! this is the design that ALL earbuds should adopt. put them in the ear and rotate the extra little nub so it wedges into the ear shell, and you won't have to repeatedly jam the buds back into your ears.
i thought i was the only one having trouble with traditional buds constantly falling out of my ears, eroding the ipod experience. i've since discovered that most everyone has the same problem. apple shud be ashamed to be shipping such badly designed buds. these really are the answer.
Very good for the price 2008-07-17
These twist-to-fit in-ear headphones didn't need the twist part for me. With the enclose foam covers they wedged in perfectly and I found them to be very comfortable and they stay in place on walks or working around the house without having to constantly push them back in.
The cord is a bit long but I hang the wires down my back so that doesn't bother me.
The sound quality is not the best but for the $15 price tag you can't go wrong.
The last thing was the description seemed to indicate there was a volume control but mine didn't have that. Otherwise, it looks pretty much like the picture.
MX 75, Great Headphones, Sennheiser delivers again. 2008-07-26
Great price.
Great audio quality.
Outstanding design, secure fit and lightweight.
I love the green color.
Excellent accessories included.
Sennheiser delivers again, I personally own another set from this maker, the HD515's, they put everything from their high end units into this small package, waterproof and extremely rugged.
Great for rougher than normal listening experiences.
The best headphones for running 2008-07-25
If you are a runner who likes to run with an iPOD or other MP3 player, these headphones are great. I tried normal ear pods and this type of heaphone was always falling out of my ears during my workouts. Over-the-head models were uncomfortable. The Sennheiser MX75 Sport heaphones have a unique locking system which keeps them in my ears even during long marathon training runs...plus they sound great. I recommend these to all fellow runners.
Fu***ng Spectacular Headphones.!.!.! 2008-07-25
Can't say much more about these headphones. If you need a pair for the gym that WONT get ruined by a little sweat.. (Sony) then these are it. Fits all ear types with the additional rubber pieces. Buy these. Very loud, relatively inexpensive...and they do the job correctly. I can't even manage to get the ear buds DAMP, let alone wet... and i sweat a lot when i workout.
Great snug fit! 2008-07-24
I've never been able to wear earbuds. They just don't stay in my ears. These fit perfectly! Volume control comes in handy too. The behind the head cord keeps cord out of my way. Sounds pretty nice. Very happy with. These are my favorite.
The worst! 
2008-07-22
Sennheiser MX55VC Twist-To-Fit In-Ear Stereo Headphones w/ Volume Control
Expensive --- VERY expensive for such a shoddy product.
Sound quality --- Dreadful! Either all bass or all treble --- no mid-range at all.
Cords --- all twisted up like a corkscrew --- very annoying. Earpiece cords are uneven lengths --- even more annoying, especially since it sets the in-line volume control off to one side, making access more difficult.
Ear buds --- The so-called "twist-to-fit" is a joke. I played around with them for a half-hour and couldn't get a better fit, no matter how much I tried.
Carrying case --- Pathetic! You have to put this together yourself and it is ugly beyond belief.
In short, the worst headphones I've ever owned. I will NEVER buy Sennheimer products again and will actively campaign against them to friends and acquaintances who might be considering a new pair of buds.
Amazon only allows posting with a One Star minimum, but I actually rate these ZERO STARS!
