The sound is great, the bass is not overwhelming, mids sound clear and the highs are crisp.
Marco Polo
I have used these no less than 4 days a week for running, working out at the gym, and blocking noise at work and they are STILL GOING STRONG AFTER 2 YEARS!!
LFuller
So why did I give it 4 stars when this problem has happened so many times (and why do I keep buying them)?

Verified Purchase
I will start with saying that I love headphone/earbuds, and I am on a life-long quest to find great sound. Actualy, sometimes I feel it is more like an addiction (like buying a new set of cans at 2:30 in the morning because I cant sleep). It is not realistic to say that these little buds are the Be all End all of pristine and perfect sound quality that people spend beacoup bucks trying to find. Not everyone is crazy like me and willing to spend $400-$800 on a set of buds or cans that will bring ever so slightly supperior sound quality. So unless you are me and have a need to stick anything that claims to be high quality in or on your ears, and you are just looking for a fantastic sound at an unbelieveable price - GET THESE!!! (But a strong word of caution - buy only from authorized retailers. I suggest chooseing ships and sold from Amazon as they are an authorized retailer and honor the 2 YEAR warranty!)

A little backround on my references of comparison: As far as earbuds are concerned, I own the Monster Turbines Pro (gold), Ultimate Ears Triple Fi 10s, Monster Jamz, Maximo iMetal w/ mic, Etymotic Research MC5, and of course the Klipsch Image S4. I'm not going to bother with much comparison of the Turbine Golds or the Ultimate Ears, suffice it to say they are slightly better sound, better Isolation, better asthetics, better accessories and hundreds of dollars more. Lets also toss out (litteraly) the Maximos, they are terrible but have a good mic. I gave them to my wife who could care less about sound quality but loves the cloth wrap on the cable. This leaves us with the Monster Jamz, the Etymotic MC5, and the darlings of cnet and therfore the internet - the mighty Klipsch S4.

The cliff's notes: I gave these 3 stars because they are very much all-or-nothing in my mind. What I mean is that they are great headphones (4-5 stars) unless you are using them to run (1 star). I use them for running -- making them useless -- but they'd be great for others. And now I will elaborate for those that care.

For runners -- terrible. As most active people know, we have a tendency to sweat. After 1/2-3/4 of a mile, the earbuds become wet (I assume) and sound deteriorates to a horrendous level. The audio level will go from crystal clear to crackly and broken in no time. Furthermore, the asymmetrical cord is a horrendous idea. It sounds great up until a point where you're running against even a slight headwind. This forces the cord to constantly blow over your shoulder, often ripping out your earbud. And while on the topic, the "tacky" rubber that the cord is made of tends to get wound up and twisted onto itself which can be downright infuriating at times -- especially a few miles into a nice run.

For everyone else -- when they are working, they sound superb. I think you'd be hard pressed to find a higher quality product for the price. The mids are great, highs are clear, and bass in punchy. These restored my faith in earbud technology; that you could get enough drive out of something so small (I'm a bit of an audiophile). The different sized ear tips are a huge plus and, when you use the correct size, they are extremely comfortable. Also, they can reduce environmental noise by a huge margin.

So there you have it. If you want to run with these -- ever -- skip them. If you are looking for a new set for the train, plane, or walking about town, these are great. Simple as that.

I've used Sennheiser earphones for many years now, mainly because of the great quality of their products. That's also why I turned to these CX 300 MK-II, when my Apple in-ear phones decided to call it a life after some 5 months of use. These are half the price of the Apple ones, and the sound quality is better by no small margin. They are very comfortable to wear, even after hours of use. They come with a selection of small, medium, and large interchangeable fittings, allowing one to find the ones best fitting your ear size. They also come with a small satchel in which you can carry them. This little bag, however, is nothing to shout about. I never use it, finding it nigh on useless.

Highly recommendable. Very good sound for a small asking price.

these were my first pair of higher quality headphones ever. I bought them about 4 years ago. I paid $50 for them. After hearing how awesome the sound was, I thought to myself "if these were only $50, I wonder how great the sound would be if I spent $150 or $300." And so I did....I bought the Sennheiser 595's (GREAT cans), I got the Monster Turbines, I got the Shur SLC2, I got the Sennheiser PX200's, and I got two other kinds of sennheiser earbuds which I ended up giving away to my girlfriend and brother. Don't get me wrong, all of these new headphones I experimented with were great. But I can honestly say that these are STILL my favorite all-around headphones. Matter of fact I am bumping some Radiohead in them right now. They are awesome for all kinds of music - incredibly balanced bass, superior sound quality, awesome noise reduction, everything you could possibly want. hip hop, classic rock, soul, jazz, blues, electronic are the styles of music I listen to most - great for all.

I will say that you may want an alternative pair for the gym, as they are not perfect for running cuz of the cord. Other than that tho, I have used and abused the hell out of these things. I have stuffed them into so many pockets, duffle bags, computer bags, drawers, leave them in the car in the summer. You named it, I've done it with them and they are still perfect. hopefully you will all be as lucky as me and get a pair that lasts for a very long time.

I just wanted to come on here and share that thought, as it just dawned on me while I was listening to some music how much I really do love these things, and how I still somehow always grab for these 7 times out of 10, even when I have an entire collection of great headphones to choose from. It could also be a comfort thing I suppose....they are easily the best fitting headphones I own.

that is all.
