Thank you for the nice ear protectors! I have already put them to the test and they work great since my ears have become more sensitive over time and a product like this is like heaven sent. I did not mind the battery installation being a little difficult since maintenance of your equipment requires you to know how. It did come apart easy enough once you know where to install the thin flat screwdriver to separate the ring from the cup. I like it's ability to compact to take little room in a range bag by folding up like a ball.
