it came quickly but the when it was delivered hard to get in to the package and the the jack was a 2.5 jack when i needed 3.5 jack, so no good to me as i had a ipod classic 160gb, its all in the details

 Nice sound quality and solid construction

I bought these for my Nokia 6220c which (irritatingly) comes with 2.5mm socket. The phone's music player software actually produces pretty good sound although I did eventually replace it with Oggplay for its FLAC support. The Nokia bundled headphones are not bad either but are not that loud and not sound isolating so basically you can forget listening on trains etc. The sound from the CX300 is lovely with the bonus that you can actually listen to it in a noisyish environment. I'm fairly careful with delicate things like headphones but so far no construction problems even though I have in fact given them the occasional hard tug by mistake. Very satisified.

 Moaning about the packaging??

Lol, I can understand why someone has moaned about the packaging as they are well packed and it takes a few minutes to get in but come on!! The earphones are absolutely fantastic brough me a set and then the girlfriend did too!! The bass reproduction and range of sound is awsome!! I have loads of earphones such as Philips ear gear and JVC Marshmallow and none of my others are anywhere near as good quality or as comfortable as these! Seriously im marking these on sound quality and comfort, not packaging.
