Use these daily as a Range Safty Officer. Other walkers I have used indoors amplify the AC system blowers to a point u can't clearly hear a person talking. This Recon unit has a superior ability to no amplify thise sounds but still increase the volume of the spoken word. Happy with that. The major knock is the lack of ability to easily replace or upgrade the ear pads with gel. You have to cut the original pads off to do so and the plate they are mounted to is fixed, so u have to use pads the have self adhesive. That is what keeps the Recon from being 5 star.
