Input:
The 3M Peltor Tactical 6S was my first venture into electronic hearing protection.  I was either going to purchase the 3M model or the Howard Leight model for a similar price.  I honestly think I should've purchased the Howard Leights, although I haven't used them, I'm just kind of "blah" towards the 3M model.  As others have stated, installing/replacing the batteries is a major PITA.  Also, the knobs are very prominent and supposedly have a tendency to switch on when you're not using them.  I must note, this hasn't happened to me, but I can see how it would happen if you throw them in your range bag.  I see no purpose for the knob itself, the headphones are useless for me on all but highest setting.  It should be a simple on/off switch.  They also seem to run small.  I by no means have a "big head", but wearing glasses (as everyone should when shooting) I have to have the headband positioned very far forward and they are tight against my skull.  This can cause headaches if you are out on the range for more than a hour or so.  I still have them 3 stars because I've never used electronic hearing pro before and I love them compared to standard ear plugs or ear muffs.  I have significant hearing loss due to military service and I can't hear a damn thing with "normal" hearing protection.  So, donning these for the first time and being able to have some auditory situational awareness while shooting was awesome.  I will be purchasing a higher end model next time or an "in ear" type protection like the SportEar.  To summarize,they are worth the $50, but don't expect to impressed if you have experience with higher end electronic hearing protection.  Semper Fi.
