For those of you looking for some electronic muffs, here are some suggestions/brief reviews. Before I start, I ALWAYS wear plugs under the muffs as well. Needed? Maybe not, but it helps even more. Back in January I came across a killer deal and got 2 of the Peltor Tactical 6S muffs. My biggest complaint about the 6S has always the "audio managment". While they work as intended, the audio is not very loud, the batteries are a pain in the ass to change out, it takes 4 batteries (2 each side), it EATS batteries like no tomorrow, you have 2 volume controls (1 each side). However, BIG plus is the low profile which I really liked. Also, very good fit for smaller heads (fit my wife better than me). Price: ~$60-ish So I kept going back to the Howard Leight Impact Sport muffs and finally decided I will sell one of the 6S and pick up a set of the Impact Sport. While still "low" profile, they are definitely bigger than the 6S (see pix) and also are built a lot better (my opinion). However, vs the 6S they have couple things going for them: only 2 batteries under the black cover, a lot easier to change the batteries, 1 volume control, they can go pretty loud and the audio management is a lot better, fit seems to be a lot more comfortable for me, and another cool feature is the AUX jack which will allow you to hook up a ipod or whatever. Price: ~$50-ish Anyways, anyone looking for something in this department, my recommendation is the Impact Sports. Eventhough, for the money I do not think you can go wrong either way.
