I dont have gromets but do get ear infections and painful ears after surfing. I recommend 'Ear Putty' which I bought from Ebay, cant hear much once they're in so be sure to keep your eyes open when going for a wave, it's difficult to hear someone shout you off it should you inadvertantly drop in....except when DBB shouted 'SAR NO!!!!' when I was about to drop in on a longboarder at Saunton
Have heard of people using 'blue tac' (other wall tacking substances are available
) to good affect. Worth using ear plugs anyway, especially in cold water.
Im not sure of the deal with gromets so speak to your Pharmacist but my nurse recommended 'Ear Calm' over the counter of your chemist for when an outer ear infection first starts or fresh lemon juice as the bacteria dont like the acidty and will die off.
Please dont wear Speedo's, no matter what is in/out of fashion there will never be a bigger faux pas than the mans speedo!!
