The biggest problem I had with mine, before I sold it was,.. with the walkers game ear in one ear, I lost my since of direction of sound. In other words, which ever ear I made bionic with the product, it would hear things that my other ear couldn't, and onceI lost the ability to hear things in stereo, I lost the ability to determine which direction a sound was coming from. Drove me nuts being able to hear something and not knowing where the sound was coming from!
I have since bought the head phones and I wear them when I'm rifle hunting. Mostly for hearing protection, but it's nice to be able to carry on a conversation, in between shots, without shouting. Mostly while shooting prairie dogs, and while calling coyotes!
