On top of that thin wires like this get more easily tangled.
Jesse A. Safir
This is the second pair I have, the first one lasted a few years - far longer than any earbuds I've ever owned.
E@gleyeZ
The sound is great, the bass is not overwhelming, mids sound clear and the highs are crisp.

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.

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.

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 had a pair of these for about a year and because of my misuse(yanked on it while it was still attached to my laptop) the wiring broke near the connection. Of course it was still under warrantly and they just sent me a completely new pair for free.

Maybe it's just my ears but I have yet to use a pair of headphones that are more comfortable than these. The way the right ear piece is longer than the left makes these headphones great for working out and the way the ear buds are designed they will not fall out unless yanked on.

The sound on these are amazing of course, It is Sennheiser after all.

During the time I had sent the Sennheisers for repair I decided I wanted to try another pair of headphones. Did some research and looked up some reviews and came across Klipsch IMAGE S4 In-Ear Enhanced Bass Noise-Isolating Headphones. I ordered a pair from amazon and the first day of use I already hated them. No matter what ear piece I used it just wouldn't fit right. They kept slipping out during physical activity. The sound was rather muffled compared to the Sennheisers and this is definitely just me but the feel of the wiring just wasn't satisfactory.

Anyways my new CX300 II are back and that is what I'm using atm. I'm going to sell the s4 headphones to one of my buddies for half the price. OH don't forget the CX300 II are cheaper than the S4s as well! By like $20-30!

I LOVE THESE HEADPHONES I HOPE YOU DO AS WELL!
