It always amazes me that people will spend thousands on a Blaser and more thousands on the best Swarovski scope but when it comes to your ears a few hundred quid is too much!
I see hundreds of people a year with hearing loss or tinnitus because of noise damage. Once it's gone its gone. Buy the best you can afford. Speak to experts in the field (audiologists) and get fitted ear pieces for stalking/game shooting. Buy the Deffenders with the best sound attenuation for the range/clays if it doesn't state it find out from the manufacture, they have to state it. On range days also wear sponge ear plugs then put the defenders on.
This is not a dig at the OP and I am sorry if they think it is, it is rather a wake up call to everyone who shoots without some form of ear protection.
