I ended up settling on the Comply TSX 100 medium fit as I really like the Comply and find them comfortable for
long listening sessions.
I have to say I think the Shure 846 far superior to my Sennheiser IE 800, which have disappointed me from the start.
I still love the Final Audio Design FI BA SS though.
Now another question if I may. If there anywhere in the UK that supplies alternative cables for the Shure 846.
Toxic Cables do not mention the Shure range on their site , unless I missed it.
