I bought these to get amplified sound on the ranges as I can’t hear anything in surefires. I’ve been issued peltors now so i don’t need them. They are brand new never been used except to test. They come with brand new batteries in. I connected my phone to them. So you can listen to music or take calls with them which is great. They really do amplify low level noise to a high degree very similar to Peltors if not louder. Please look at the photos carefully, a lot of the features are listed on the box. Brand new never used.
