Dunno if this has been done before but here goes anyway.
I find the little foam earplugs uncomfortable after a time and fancied some of those custom fitted jobs. How f*%$ing much? Right, what about diy ones? Little kit, enough to make one pair, about a tenner. What if I balls it up? Did some research and bought some silicone putty from eblag. Got enought to make a set for me and a set for both my son and daughter, and I have enough left to make two or three more pairs. The cost of this, about £6! Bargain. For the record they are the most comfortable ear plugs I have ever had.
Took about 5 minutes and was a piece of cake to do. Highly recommended.
Cheers all, Neil
