The prices vary depending on quality and purpose. For example, for hunting you might want amplification (my daughter-in-law says it's somewhere in the range of $500-700 depending on manufacturer).
She made me a pair of custom plugs with passive filters that I wear under my muffs (plug filters are changeable for different purposes, like shooting, music, or solid for max protection - these are around $225 or so, prices vary). Keep in mind that in-the-ear plug, even custom molded, will not offer anywhere near the protection of over-the-head muffs for indoor shooting (ideal is a combo of the 2). For hunters a good pair of custom-fit electronic plugs might be helpful. Please PM me for her name and tel # if you'd like more info.
