These 'phones throw out an amazing amount of bass, so much so that in order to get Rock; G n' R, Metallica, House of Pain to the level I like it, I had to change the EQ on my iPod Classic to the Piano setting!?! But for Dance music and Electronica; Faithless, Fear Factory, Paul Oakenfold they just keep on pushing like nothing I've heard. The sound from these headphones is so pure, you just have to switch to some Bob Dylan or Fleetwood Mac to be sure. Being the owner of some very expensive hi-fi, if I knew all it would take to get this kind of sound was an iPod and these headphones I would have switched a long time ago. They are extremely comfortable too. I had them on for around 5 hours at the time of writing this and at times I couldn't even feel I was wearing them. I've always been a Sennheiser fan and this latest purchase just confirms my belief in their technologies. The only gripe I have, and its a bit of a non-complaint really is the cord is very long. I plan on using them with an iPod for the most part but they are no doubt designed for sitting down at home or DJs who need a lot of movement. But, I believe a shorter cord is available so as I say, it really isn't a problem. Do yourself a favour, you won't look back.

These headphones are really good value for your money, and I would definately advise anyone who is looking for a pair of headphones with in £20-£30 should look here. It has really good noise cancellation, even my own speech was very muffled when wearing them, and you can listen with privacy as no one is going to be able to hear what your listening to. The bass is good- better than the original ipod earphones which I thought were perfectly good. In fact most instruments were much clearer. They have a long cord too, so if you need to plug them in round the back of your computer it will reach without you having to bend your back awkwardly to listen to music for short cable headphones. I also listen to a wide variety of music ranging from classical to ballads to RnB all the way to pop and rock and they produce good sound for all genres in my opinion.
