The plastic around the audio jack broke after only a few months of use. This could be due to earbuds being plugged into an iPhone 6+ which leave much room in my pocket, putting strain on the L-shaped jack when taking my phone in and out of my pocket. I rode the subway to work 5 days a week last year, and was constantly taking my phone in and out of my pocket to change the song which inevitably put stress on the jack. I'm living in South America at the moment, and it isn't recommended to keep your phone out on your lap or even in your hand while going place to place. As is such, the jack broke so I ended up having to tape things back in place, though the cable eventually got too twisted/frayed and now only one of the buds works, the other intermittently. The jack is not made of the highest quality/most sturdy plastic, but it shouldn't be a problem if you're cognizant of the issue. This issue is not nearly enough to put me off from these earbuds.
This brings me to the second issue. You have to take your phone in and out of your pocket constantly the change the song, to answer a call/text, etc. because there isn't a microphone or pause/play button. And because these headphones are wonderfully noise-isolating (which I'll get to in a minute), you have to either pull them out of your ears when someone starts talking to you or pause your music directly on your phone/mp3 player which can be inconvenient if placed in your pocket or bag. This issue doesn't nearly ruin these earbuds for me.
The third issue is that of having two different cable lengths between the earbuds. This supposedly helps prevent tangling, but I haven't noticed it to help at all. All this does is make the headphone tug on your ears unevenly when you inevitably have to take them out to talk to someone (because there's no pause/play button). I resorted to wrapping the longer cable around the back of my neck, or else the slack from the longer cable would annoyingly hang in front of me and unevenly distribute the tugging weight between my ears. Still, this issue doesn't turn me off from these earbuds.
Before I get to the pros I'll note that the problems with the jack and the tangling could have been avoided if I took a little better care of these earbuds. I got these earbuds mostly for commuting and to toss around without worry, unlike a few other pairs of earbuds and over-ear headphones that I use at home, on airplanes, etc.
For the money, the sound quality is unbelievable. Sharp highs, clear mids, and deep, booming bass that I've rarely found in any earbuds at any price level. This versatility came as a very pleasant surprise to me. Like my more expensive over-ear headphones, I found myself discovering new layers to some of my favorite songs which is always awesome. This has to do with both the clarity of the earbuds, as well as their excellent noise isolation characteristics. To reiterate, sound quality on these earbuds is truly out of their league.
Noise isolation is excellent as I mentioned. The earbuds come with three different size rubber inserts. Whichever size is good for you (the large ones for me), they fit snuggly and comfortably in your ear. The few times I've taken a long bus ride and didn't want to take my over-ears with me, these stayed comfortable in my ears and kept my ride quiet the entire time. They never fell out, needed to be adjusted or needed a break from due to discomfort. Unlike comparable earbuds, you don't have to jam these ones in your ears, sacrificing your listening comfort, just to reap the benefits of their noise isolation. As they are noise-isolating, not noise-canceling, they don't require batteries or charging which keeps them light and as far as I'm concerned and puts them at no disadvantage to noise-canceling options when it comes to blocking out surrounding noise.
Minimalistic design. The headphones are completely black except for small chrome rings and the hardly noticeable Senheiser logo on the back of the earbuds. You could argue that their design is boring, or maybe even cheap (it just says CX300II where a microphone should be) but to me they're perfectly subtle and understated. If you're looking for blingy earbuds, look elsewhere. The swagger of these headphones comes out in the areas where they truly excel, in the aforementioned sound quality and noise isolation. Seems like these earbuds were engineered with their performance in mind before anything else, and that's okay with me.
If you take care of these earbuds, can look past some slight design flaws, I promise you will be very VERY happy. These headphones seem to be unrivaled at this price range or even the next level up when it comes to their strong points. Sound quality, comfort (after some adjustment) and noise isolation are the most important things to me, and let's be honest...headphones don't break themselves and you can certainly be more careful with them than I was. Having learned my lesson, I'm ordering another pair without hesitation. Now that you're informed, you should too!
Sound quality is excellent for the price, and while Sennheiser says the headphones offer powerful, bass-driven stereo sound it’s not as overwhelmingly bassy as that might sound. Given the weighty sound of the CX300’s they’re well suited to rock and dance, but they impart a warmth that is also good with jazz. But that’s not to say they’re not detailed as they unearth parts of the music some other headphones can obscure. But most important of all, they make music fun.
Pros: Great Bass for electronic music an other genres
Cons: Tangle VERY VERY easily, takes about 1 minute to untangle, after 1 and a half years the earbuds started to give out.
Update: bought this product in May 2014 and as of January 2016 the right earbud piece does not emit any sound. My guess is that the wire started to fray from the constant coiling.
Even after the update, these headphones are still B-23 approved.
