Input:
Pros:
-They do what they claim.  I can hear every word of people around me, but when the gunfire starts they shut off and my hearing is protected.
-They fold for compact storage

Cons:
-They are extremely hard to take apart to get at the batteries.  This wouldn't be too bad except....
-You have to remove the batteries before you put them in storage or they will corrode, so every time you use them you need to open them all up again.
-It's easy for the knob to get hit and have them powered on draining the battery.  No LED telling you they are on.

Options:
A: very positive
B: positive
C: neutral
D: negative
E: very negative
Answer: B: positive
