Uncle jaffa's review of how ear plugs worked for him. ( note that opinion, is based on how it worked for me )
Number 1.
Docs Pro plugs, comes in various sizes and has a between the ears leash, fitted well and no water entry.
Hearing diminished somewhat and when I was walking in, each footstep produced a loud drum beat in my ears, annoying. After a big paddle I could hear my carotid pulse , sort of OK.
The leash part was at times annoying as my surf hat chin strap and ear flaps kept catching the leash and tugging a plug out if I turned my head suddenly. No irritation of the ear canal.
Number 2
Speedo brand blue ear plugs, prevented water entry well, major hearing loss and reverberation if I spoke. The sticky out bits caught on my surf hat and made loud scrapping sounds if my hat moved, again carotid pulse and footstep noise. Slight irritation from the plucking of the stub end of the plug by the surf hat.
Number 3
The surf ear plugs. Great presentation and storage case, a bit of a performance to insert at first but each time was easier as I became more proficient in placing them.
No water penetration.
All the same sound issues (drumming and heartbeat )and were there but the overall hearing was better, the blue hook was good to hold in the ear but I felt like it was always about to fall out ( probably wouldn't because of the surf hat) but I kept readjusting it.
The fiddling with the plug also produced some feeling of ear canal soreness and slight inflammation ( in fairness this all could be due to first usage and possible not doing it right).
There is also my dislike of ear plugs overall fiddliness and for me just another thing to think about ( often forget to use them) and after wearing hearing aids all day, nothing in my ears feels great.
Thoughts on blue tack, ear putty, silicon balls etc., I wonder about ongoing cleanliness of the substance after a few insertions as the surface is folded and reworked so any stuff becomes part of the plug ( possible source of infection). All the plugs mentioned above can be cleaned by alcohol (Aquaear drops etc).
All plugs are miles better than having the operation to remove boney exostosis from you ear canals. Beside if you have the Op and don't plug the boney growths happen again.
