Better than E10's for under £50?

Hi all

After leaving my Beyerdynamic DTX101ie on a plane  and losing my Soundmagic E10's in the last month  I am after a couple of pairs of in ears for use with iPhone (office) and iPod (travel).  Both the above pairs were excellent and difficult to tell apart really; perhaps with the Beyers having a slight edge sound and build quality wise but there really is a hair's breadth betwen them.

So I am after a couple of new pairs and am tempted to either go for the same combo again or simply invest in 2 sets of the E10's.  I have seen the SoundMagic E10M with remote but they are £15 more and not sure they are worth the extra?  I have also looked at the usual hight st fare from Dixons and remain extremely underwhelmed.

Before I do is there anything else out there worth a listen at this price point?  Music mainly rock.

Thanks in advance.
