What do you think of around the neck ones vs earbuds? Wireless is good to get the cell phone away from the body. https://wavtubes.com/ looks like the best we have.

Have you studied the work of Dr. Olle Johansson on nnEMF? He has some interesting thoughts that even very weak signals can be very damaging. Johansson's thesis is that the body — particularly the skin and immune system — responds to nnEMF through real, measurable, non-thermal biological mechanisms, primarily mediated through mast cell activation, histamine release, altered neuropeptide expression, and immune dysregulation. These effects occur at levels well below what current standards consider dangerous, because current standards are calibrated only to heating effects and are therefore fundamentally unfit for purpose. He goes further than just critiquing regulatory limits — he argues that measurable cellular disruption occurs at exposures orders of magnitude below what we currently consider safe. Even electromagnetic fields at levels of only 1/100,000th (10⁻⁵) of what we are regularly exposed to from mobiles are found to disturb the complex electrical operations taking place at cellular levels, and to cause damage to DNA, proteins, neurons and oxidation processes. In short, Johansson's position on field strength is that the question isn't "is it strong enough to heat tissue?" — it's "is it strong enough to disturb biology that evolved in an environment 10¹⁵–10¹⁸ times quieter?" And by that measure, virtually every modern wireless technology qualifies as a significant biological stressor. TL;DR: Putting Bluetooth, WiFi, or 5G tech in your ears or on your body is madness.
