I am looking for a set of good headphones for £100 - £150 that are very good with movies and games but are durable. The akg k550 are now £99 is that a good choice for my average size head due to fit and seal issues from other users. I was also looking into the shure se 840. This is portable but is it  suitable for movies? what's there sound-stage in case I use them for gaming as well? I am worried that the akg k550 will not fit my head so the shures seem like the best bet. Also the senheiser hd 558 will need an amp to run off  my i pod 4th gen and  I don't want to buy an amp yet because don't have the money. Any other suggestions are welcome
