It's just about tricking senses to make your living more pleasant. Same way you do with comfy chair or woven clothes or warming up air around you beyond what's needed for survival of taking warm bath or wearing sunglasses, or tinted glasses. Better tech just gives you more comfort.

I would argue that buying an ergonomic chair goes way beyond tricking your senses. There are actual mechanical forces that support your body weight in ways more conscious of your anatomic needs; e.g. the chair is simply better, no trickery needed.

Wearing sunglasses could be seen as either way. You are definitively dimming the raw luminous stimuli that reaches your eyes, but you could argue that your are not dullying your senses but just filtering a part of the spectrum with low signal-to-noise ratio, so your senses are enhanced as a result. Technology can be seen as an extension of human capacity. That's what tools are all about.

This thing in the ear, it does not give you beyond human capacities, neither helps you recover regular capacities you lost by whatever circumpstances. This just let you pay for the privilege of not having to develop your capacities to begin with.
