Went out today, only did 30 minute stints but found them to be very good.
Found they blocked out a lot of wind noise and I felt I was able to enjoy/concentate on the ride more, I got the impression I was riding faster than normal due to less distractions.
They take maybe 5/10 minutes to get use to them being in place due to the a bit of silicon pushed in your ear, I do get a bit of ringing in my ears, due to all the gigs I went to as a youngster but that is not a problem.
I did not feel shut out from the outside world or unaware of what was going on around me, more of being focused whilst riding the bike and enjoying it more.
I know the cost me £64 (bought at Donington), but I would recommend them to anyone who suffers from a "noisy helmet" (suites you sir).
When I try them on a long motorway ride I'll the add my comments to this thread.
