Used to occasionally use the disposable ones at the airport... I'm susceptible to ear infections any way, but unless you're a monk, constantly taking them in/out and putting down somewhere can only lead to picking up bugs etc... Was told it didn't matter if you used a hundred pairs a day, but replace with new each time.
Number of people you see bumbling around on the road with headphones in is frightening.
Blocking off one of your key senses on the road strikes me as daft tbh 
It's not blocking it off though, removing wind noise but allowing other sounds to remain. Such as engine/cars, as just 15 minutes on a motorway can damage you hearing.
Have you actually tried riding a motorbike, with no ear plugs at 70mph? 
Bit of reading for non-bikers without actual experience or get why they are needed: http://www.hearingtestlabs.com/motorcycle.htm
No, nor do I ever intend to 
That said, I doubt you've stood on an apron with four RB211s a full chat next to you... 
I contributed as a user of the disposable defenders, but obviously not being a biker makes me a second class person apparently
have to say that I'm with Aaron on this... to misquote George Orwell, "Four wheels, good. Two wheels, baaad."
Always so sodding difficult to have a conversation with you

So you have no
actual experience of what we are talking about here, using ear plugs occasionally at airport and on a bike daily are a tad different. I never stated 'second class person', where did that come from? WTF?

Similar to tyre threads, you often don't like people giving opinions with zero experience of the situation and product.

Four wheels good for London commute? No.
Two wheels bad for London commute? No.
35 mins and always parking available vs 55-90mins and no parking past 08:30. Go figure
