I “simply” prefer a wired headset because I don’t need to recharge it. I use Bluetooth in some situations, but not for this. So if a headphone connector is really missing like in “all those other phones”, I will definitley not buy it. Or maybe they want you to buy a USB adapter for it?

I wouldn’t buy a phone without a 3.5mm jack either. I hope there is a jack fitted as without one it would rule FF4 out as a potential replacement for me. Not that I’m planning to replace my FF3 until it kicks the bucket… Well unless the FF4 is just so irresistable I have to have one then I’ll be in the queue for another 2 year payment plan!
Though I prefer bluetooth headphones, there is always a pair of wired headphones in my bag for when the bluetooth battery goes flat. I’ve done my time with phones that need headphone apapters. Just an extra breakable bit of kit to remember! Plus it adds to the carbon footprint of the phone.

Radio waves don’t damage your body. They can only heat you up, if they’re strong enough. And with strong I mean a high energy output, like a microwave. A microwave and Bluetooth have a thing in common, they both use the 2.4GHz frequency. Just like WiFi. But your phone and router don’t use a kilowatt of power. A higher frequency won’t make a difference either, such as 5GHz WiFi. It’s not ionizing radiation, so it can’t damage your cells and thus doesn’t trigger cancer.
You can buy an adapter for your 3.5mm headphones. The only reason that sucked with my Pixel phone was because my battery doesn’t last very long. So using the same connection for your audio and power is kinda problematic. But with a FP you can swap the battery.
2.4GHz is all around you, if you use Bluetooth or not. It uses the ISM band, a very common and popular used range of radio frequencies, for a very long time. There is no proof it causes damage to our health.
I’m not aware of your expertise but I worked on radar in the Royal Navy and whereas you are right in that heat develops, it happens even at very low levels, and can be uncomfortable and psychologically damaging once it’s noticed.
Further another oft unmentioned aspect is resonance, 2.4Ghz will resonate on any form around 12.5cm which can effect lobes and scull partitions, etc.
Whereas the impacts may not be obviously serious, over time they may also produce a numbing effect.
For example every object has a resonant frequency and acts as an antenna.
If all you hair is 1cm long you will pick up 30Gh a lot more than someone with hair of various lengths.
Whereas these may not be as damaging as the words of politicians and religious zealots to ignore them would imply a lack of awareness of physics both tradition and molecular.
I absolutly agree with you, if there is no headphone connector I will not buy the FP4.
