Help replacing my Denon ACH360

[nikolarun]

Hi All,
First post here , so be gentle

My Denon ACH360 are about to give up the ghost so I'm in the market for a pair of IEs.
Short list is :

Soundmagic E10 - £35 + £12 for buds
Denon ACH360 - £26 ( just a replacement )
Denon ACH710 - £80
Sennheiser IE6 - £80
Shure SE215 - £70
Beyerdynamic DTX 101 - £65
Phonak 012 Perfect Bass - £80-90

I use a Cowon S9 and most of my music is in FLAC format.
I mostly listen on the tube, so good sound insulation is important.
Music is Hard Rock, Heavy Metal, Soul, R'n'B depending on my mood.

I am prepared to spend up to £80,but cheaper will do

Regards
Nick
