The sounds are a bit different, but I really like them and little ambient noise or wind issues. I talked to the owner, and they are empathizing quality of build. The switches {pairing, power} easily turned on maybe a little too easy was my only concern but with hundreds of hunts I have not had any failures. They pair up almost instantly and have a 50-hour run time on a single charge. We just returned from a UK 2-week hunt and they worked perfectly. They are not waterproof so when it rained just throw up the hood and keep swinging.
