Stubby, on the PRO 9's I got myself a pair of these about a year ago having not got on with having something in my ear canal such as plugs nor did I get on with the ear defender style of protection. I ve used these in the field and at clay shoots and find they do the job perfectly. Very light, sit just in the entrance to the ear canal and they fold up nicely into an old glasses case to protect them, Amazingly simple! Why pay more?
