I have more than one pair of Pro Ears and they are excellent!
That said there are a few things to keep in mind:
1) They are FAR from cheap - Usually $220 to $250, but well worth it!
2) They are BIG. Not really comfortable for rifles, but near perfect for pistols.
3) (answer to add on) They respond so quickly to noise pulses and the
resultant lowering of sound levels, that they are SAFE to wear for indoor
ranges. Older types (I used Peltor for years) would respond to the noise
pulse and be opening back up as the echo would hit. Result? You would
have your ears ache after a minute or two, because the electronics in
the Peltor would have to open up completely before it could clamp down
again. Pro Ears does NOT have that problem. - - - Watch out for other
manufacturers (than Peltor) that have that problem. As I say, Pro Ears
DOES NOT.
4) If you decide to get Pro Ears, BE SURE you get the ones with at least
-30db NRR! They come in ratings of -26 to -33db. Pay the
small difference
for what you want/need.
Watch the demo (3:30 min) and you will see. I say from experience that
what he says (about the Pro Ears) is true.
