I've bought a pair recently and am really impressed with all the extras that came along with the earphones and the material quality.

These are extremely comfortable and I can even sleep with them as it was kind of an earplug.
Sound quality is pretty decent, however in my opinion these could be just a little touch louder. Maybe Sennheiser made them this way because they're in-ear and could damage ear drums, I don't know.

As I've seen on some reviews, there are the following "issues":
1 - You can really listen to your footsteps if your shoes have a hard sole.
2 - Every touch that you do on the cable is very loud, so, make sure the cable don't move a lot. Sennheiser inclueded and cable clip which helps in this case.
3 - When it's windy and you're walking against the wind you can hear it, but I only noticed it in really really quiet moments, hardly any music playing so this for me is not a problem.

These are the first in-ear phones that I've ever used so I don't know if these "issues" above are valid for every kind of phone like that or not.

Overall, I'm a very satisfied customer and would gladly recommend it.

I got these to replace the 'phones that came with my iPod Touch. I think the iPod earphones are too quiet, especially when watching video, which can have a very wide dynamic range. Watching video on an iPod in a noisy place can be frustrating, even if you've tried all the tricks to get the sound up.
So I bought these hoping they'd drown out the background noise, and even if they weren't actually louder, they might seem louder. In practice, not only do they seal out your fellow passengers on the train, they are also a lot louder than the iPod earphones to start with. so much louder that I nearly blew my head off when I first tried them! Top marks for loudness.
The next thing you notice is that there's masses more bass than the iPod earphones can manage. If anything, there's slightly too much, but I've never liked a bass heavy sound.
Perhaps as as result of all that bass, it seems to me that the treble is a bit subdued in comparison. But they sound pretty good overall. The sound is very 'tight' and 'robust' like a pair of good speakers - very clear too and detailed. If you travel by bus, you will notice a massive difference over your standard iPod 'phones. It's as though the bus is heavily soundproofed and all the passengers are whispering. It's almost surreal.
A major (but one-off) annoyance was the nuclear-bomb proof packaging. Before you buy, have a pair of goggles and a tool kit handy...
Inside the packaging (if you manage to get inside) you'll find three different sets of rubber plugs for different-sized ears. The ones already on were fine for me as it happened. There's an extension cable too, but the attached cable is long enough if you have your iPod in a jacket pocket.

I'm thinking of buying a pair of these to use with my Sony Ericsson W880i - why? Because it has a SPLIT cable - yes, everyone, Mr N. Hamilton, Mr D. Morris and the rest - you obviously haven't read the small print. These headphones have been designed for mobile phones and other such devices that use a manufacturers own bespoke connection cable that then has a 3.5mm jack socket at the end (because the devices themselves don't have their own 3.5mm jack socket). Sony Ericsson supplied a pair of 'in ear' headphones with my W880i (that were very short) to plug into their own connection cable. However, I replaced those with a pair of CX300s which greatly improved the sound but meant I had a total cable length that was far too long. Thus, these CX400s have been produced to replace existing short headphones supplied with these kinds of devices!!! Bottom line - buy the CX300s or CX500s if your device has a 3.5mm jack socket. If it doesn't and you have to use non standard cable to connect, then get these!!!

I have been using a pair of Sennheiser's CX300 phones for some time and have been blown away by them, so when I heard about the CX400's I thought I'd treat myself.

Oh dear, what a disappointment. These are not in the same class as the 300's - and cost more! The fabulous bass extension of my 300's has gone, and would seem to have been replaced by an over accentuated top end. The result: a pair of phones no better than 'run of the mill' phones from lesser manufacturers.

This type of headphone has to be carefully positioned in the ear canal for them to perform properly and a little practice is necessary to get the best from them. This was the case with my CX300's, but no amount of fiddling helps with these offerings. I did wonder if I had managed to get lumbered with a cheap copy but close inspection reveals an attention to detail and a quality of construction I doubt I'd find on a copy. It's possible though, I suppose.

My instinct is to say "try before you buy" but the packaging had to be destroyed in order to open it and I can't see any dealer going for that!

Sorry Sennheiser, if these are the real deal then you've shot yourselves in the foot. There is no way I can listen to these after the CX300's.
