forcing you by including wired headphones in the box and wired headphone adapters in the box and not even having the bluetooth headphones available at release date? That kind of forcing?
long-term exposure to EM radiation cannot be good, no matter how much low-power it is.
You realise that wires radiate E/M as well, right? And that light is 'electromagnetic waves'? and that radiant heat is too?
Yes, Apple has included those wired headphones, too. But don't forget that the focus henceforth is on "wireless" headphones, about which I wrote my concerns.
You can ignore the facts and go on and just "trust" these companies, or you can read for yourself and realize that not every new technology is inherently good for your health.
The power in the signal between the phone and the nearby base-station/cell-tower is going to be orders of magnitude larger than between the phone and any bluetooth headset.
I don't think anyone is arguing that using bluetooth headphones is 'good for your health', just that it's 'not bad for your health'. I'm not aware of any mainstream studies that have shown adverse effects from exposure to 'normal' levels of radio waves of the type produced by consumer products. I am open to being proven wrong though!
I often listen to audio on my iPhone through wired headphones as I'm going to sleep (either relaxing ambient sounds, or podcasts).
When I do this, I put the iPhone on Airplane Mode to disable all radio transmissions. I also keep any other radio transmitting devices well clear of the bed (this is commonly recommended for people who have impaired sleep, which I do).
On any occasion when I neglect to enable Airplane Mode before falling asleep, I awake feeling significantly less refreshed in the morning (or even awake in the early hours of the morning feeling terrible).
Given this, the prospect of having to switch to Bluetooth headphones while I sleep is at least somewhat unappealing. Bluetooth may not be as powerful and disruptive to brain waves as cellphone transmissions, but when sleep is already impaired, you want to avoid anything at all that will make it any harder than it already is.
So, I'll be sticking with wired headphones and keeping all transmissions turned off when I sleep.

Studies of these kinds of effects are notoriously hard to do accurately, as they usually study a random sample of "average" people, but don't/can't take into account increased sensitivities of people who fall outside the norm due to illness or other factors.
Anecdotal evidence is often sneered at by those who pride themselves on being only persuaded by "data" and "evidence". But those of us who fall outside the populations represented by the samples usually included in mainstream studies learn the hard way that anecdotal evidence is the only way for us to figure out what is good or bad for our day-to-day wellbeing.
BTW, it is completely ridiculous to think the Sun is more dangerous than manmade wireless devices.
Plus, how come there weren't reports of people (self)diagnosed with "hyper-sensitivity" to EM waves, before the "wireless age"? By your claim, billions of people who lived before us must have been felt similar effects on their body, but as far as I know, they were fine.
Omnidirectional antenna on the other hand, transmits information in all directions (kind of like a sphere around the antenna). The transmitted power per surface is identical at a certain distance, and for the same input power, power density of an omnidirectional antenna is less than that of a directional one.
Complete omnidirectional antenna doesn't exist in practice, but sources like the Sun and wireless modems (some of them) come close to this definition. BTS towers on the other hand, make use of directivity methods to further cover the area, which is why you see something called SAR (Specific Absorption Rate) on your smartphone's box. In layman's term, SAR measures how much EM power your body-flesh absorbs because of your phone, and as you might guess, the less SAR, the better.
Please see my comment below; sneering about this topic isn't helpful or fair.
