Man, this is an awful post. So i better let you know what really works purely from a non pimping point of view.
i have one of these
its half the price of the above stuff. i have had it a year and still going strong. Awesome bit of kit.
Don't bother with the ear pieces though (for all these things).
All you need is inner ear ear buds heaadphones (Ãƒâ€šÃ‚Â£5 on ebay) and then use blutack to secure them firmly in the ear. Followed by 2" by 2" piece of brown masking tape pieces to seal off the ear completely.
No surfers ear any more and clear sound as loud as u like to boot.
And yes, you can still hear people around you even with the music remaining on.
If you don't want the music on stop it and u still have good protection from surfers ear (not to be underestimated).
P.S. It took me a year to finally work out what works best by the way aquapacs included. Here's a link for the type of earphone that works best
