Summary: I bought these headphones 6 months ago after having a pair of Sony Fontopia's that split after more than 1.5 years of daily use. The sound quality is good, but the rubber has started to split around the ears exposing the wires. For the price, they're not bad.
Summary: I had an ipod classic 120gb for xmas and the supplied earphones are ok but I wanted something better so read as many reviews as I could and began my quest, I already own several headphones but have not been able to find any in ear ones that are comfortable and sound good.
Summary: These are great headphones, sound fantastic, but the wires are so frail, any dink or twist or bend in them and you loose a whole range of sound - they can take the vocal out of a song, or the bass, all by themselves. Would not recommend them to anyone who is not completely static, all the time.
Summary: After using these a bit more I thought I would update my orginal review. I have to say that they are massively dissapointing if you have used CX300s before. The sound is really hollow with heavy bass and high trebles but a compete lack of mid range.
Excerpt: I have just purchased the CX400s after my years of use from the older CX300 model. The difference is amazing... I listen to a lot of Classical, Chamber music on public transport on the way to work and these block about loads of background noise. But...
Pros: Great Sound Quality : Noise Isolating Properties .
Summary: I thought these were the dogs to begin with but I'm glad I waited until now to submit my review (some 4 months after I bought them) because the sound quality has now diminished to the extent that the music is only just audible at full blast.
Excerpt: These in-ear, noise-isolating headphones feel be a little strange when you first start using them - but don't let that put you off. Sony and Sennheiser have been offering this headphone technology for a few years now.
Summary: 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.
Summary: I bought two pairs of these for my daughters as replacements for their Ipod headphones. They were really pleased by them, comfortable and great sound with the ability to cut out external noise (great on the tube). So should be a 5 star rating. Unfortunately both sets packed up within about 2 months.
