Wow, that's a first. Who would have thought? People rarely pay attention to this matter. Not the most appetizing subject, but makes total sense. And it most likely will improve your auditory reception. Thanks for the tip.
Thirty dollar upgrade worth thousands
Helpful $30 suggestion - clean your ears! I purchased a otoscope (the instrument for visualizing your ear canal and eardrum) from Amazon for $20, called the original Doctor Mom. Plus $5 in Debrox ear drops (most recommended way of cleaning) at the pharmacy. Even though I though my hearing was fine, my wife could easily see that I had wax buildup. Clearing this out might just save you 20K in equipment chasing for better sound.
