These are the Hunter version with a little added amplification. I've never used them even though I've had them for a while. My ear canals are too small. They don't fit unless I force them. Ouch!! I have everything in tact in the box as it was sent from the Long Range Hunting store. Two sets of plugs, the units, extra batteries, instructions etc. It was purchased from Long Range Hunting store. I'm selling for $185.00 and I'll mail them free.
