Replacing my Sennheiser CX300 II's.

Alright, well yesterday I (for the very first time) broke a set of eargear.

So I need to find a new set of IEM's, I would like to upgrade a little.

I was looking at the Shure SE115, SE215 or SE315.

Originally I was looking to spend about 150AUD, which would mean I'd have to go for the SE115 or SE215. However for 200 I can get the SE315's..

I would like some advice on which one to go for. Will these be a good improvement over the CX300's I had.. Is it worth going for the SE315's etc etc.

Also I was looking at ebay for these, and I was wondering if there was a chance that they're fake?

Thanks!

Other suggestions are welcome too.

Hey, I wanna decide between the SE215 and SE315, any suggestions?

105 or 180 aud.
