Radians Pro-Amp™ Electronic Ear Muffs (NRR 23)joeJanuary 21, 2016I'm not an expert with NRR ear muffs, but I do know that the batteries in this model fit EXTREMELY tight, so much so that I was worried I was going to break the battery ports getting them in. One headset takes a total of 6 AA's, 3 on each side. The instructions also say to remove the batteries if the ear muffs won't be used for an extended period of time (I suspect the NRR slowly drains the batteries even if the volume knob is turned off). I love shooting, but I'm not so avid that I can leave my batteries in all the time. That means I *SHOULD* remove them every time I'm done shooting. That will inevitably result in a broken headset, so I'm just buying time until that day. But functionally, they work well.
