I thought I would share this as it may be of help to some people on here.
I was looking into finding some better earplugs than the disposable foam ones I get from work and found most other options are quite expensive.
So after some searching I decided to try these.http://www.hearos.com/products/rock-n-roll I got them from a local music shop (tom lee) and am quite happy with them.
They are much more comfortable and let in a little more sound than the foam ones ,best of all they don't stick out and rub against my helmet speakers.
Cost about $8
