I had my first surf last night using these
surfears.com/Having never used plugs it was a weird experience. But after continually having blocked ears and a few infections I thought it was time. At the beginning I felt a bit off balance due to the weird sound. I could hear everything but it felt off. Reminded me of how a gopro captures the water sound loudly when paddling etc.
I kept chopping and changing with them in/out throughout the session etc. I will give it another session before I decide on them though.
They could be an option for you.
