I have the CX300s by sennheiser and quite happy wiv them now they have been worn in but am tempted to go for one of the others in this range like the CX95s, CXL400s or the CX500s would I see a big difference or is it not worth it?

I've not heard those you mention, but I cant see them being a particularly big upgrade to be honest. If you genuinely want to step up in performance I'd go for some of the higher end earphones. I'd imagine something in the ~ £100 range would represent a fair step up.

I use the CX300s myself and at home, I use the HD600s (out of a much better rig) and the CX300s do not disgrace themselves even when compared with such heavyweight opposition, so I'd imagine upgrading to *slightly* better earphones is going to be a bit of waste really. The main drawback I find with the CX300s is getting a good seal, particularly when moving about.
