Bottom line, these have not met my expectations. I watched lots of reviews and everyone seemed to make these out as the best thing to hearing protection/enhancement. I'm very disappointed in the audio quality of the sound enhancement. The GS Extreme 2.0s don't perform close to my 20+ year old Dillon over-the-ear electronic hearing protection, much less my 16+ year old Peltors. I didn't expect identical performance, but I have a very difficult time communicating with people on the range and would have thought there was enough improvement in electronics to have similar quality with my older hearing protection.
