Best audio tweak ever, especially for the over 60s

What did he say? Could you repeat that.

You can’t hold a candle 🕯 to that! 🙄

There are over-the-counter products that use a gentle glycerin solution to thin earwax and let it run out.  Mostly sold for swimmer's ear, but can be repurposed here so you don't have to use Q-tips and risk eardrum damage.

There are also simple lavage pumps/syringes to facilitate the process.  Haven't tried one of those.

My best related tweak is wearing Eargasm attenuators during my subway commute in NYC. They even come in audiophile packaging for extra slam.

Get rid of all old newspapers, magazines, books. Even better hire a Feng Shui consultant to straighten out your living space. Feel better. Hear better.
