I was using in ear ipod make earfones which I thought gave a really good sound. Recently I trashed them so instead of just buying another set I decided to do some homework on an alternative set. I live in the uk so finding good headsets is an issue, otherwise its going to be purchasing online. I decided to go either for sony mdr-ex90lp or sennheiser 300's. After weighing up the pro's and con's I opted for the sony model. WoW !!!! Im kicking myself at thinking the sound quality I was getting from the ipod model was good.
