Actually the iPhone 7 comes with EarPods with Lightning Connector (in place of 3.6mm jsack).  This is according to the Apple Store listing of what's in the box. 

 

That will solve several of the issues listed below.  I guess Apple did put a little thought into this for the benefit of the consumer.

Kevin, thanks for checking in. They must have Bluetooth receivers in each earbud, but only use one channel for each--a waste of silicon if you are buying discrete Bluetooth chips but they might be finding some economical methods by doing their own silicon. Also at $159 a set they've got some margin wiggle to make the duplication worthwhile. Thanks for sharing Kevin.

I asked an Apple representative last week at the Apple event and was told Apple does not use NFMI technology. It appears that Apple uses its custom designed W1 processor to connect the audio solely through BT protocols. I've asked Apple for more details and will update EETimes if I get clarification.

 Probably best if Samsung doesn't do that seeing how you can use your "old" headphones with the iphone7, they include a 3.5mm to lightning connector with the phone.

Yes, we have heard the same rumor--that Apple is not using NFMI, but some proprietary way to eliminate the wire between the two earbuds. The wire is necessary for Bluetooth earbuds because Bluetooth streams a stereo signal to its receiver, one channel of which is stripped off  in one earbud and sent over to the other. The easiest way is a wire, but near field magnetic induction (NFMI) eliminates that wire and has been proven reliable by decades of experience with hearing aids. The only other way to do it, that I know of, is to use an analog RF signal, which may well be what Apple is doing. We won't know until the teardowns on the 16th (or perhaps even later if Apple has gone to the trouble of disguising the chips it is using and they have to be cut open by ChipWorks or such). In any case, NXP is hoping to capitalize on Apple's use of wireless earbuds to sell its NFMI SoCs, since that is the easiest solution for OEMs (which is what this story is all about). Does anybody in the know want to anonymously reveal the answer ahead of the tear-downs in EE Times?

I understand that the NXP chip doesn't use 2.4Hgz between the ears, but the iphone implementation and surely most implementations of wireless headphones will be using 2.4Ghz bluetooth to get the signal to 1-earpiece. So is this really appreciably less "slow cooking". The only mentioned exception is if the source device is within 39 inches.

If Samsung had any sense they'd use this as a point of differentiation.  "AND you can still use your old headphones!"  Sure, they wouldn't sell any new headphones, but if they sold 1 more phone that's probably the same as selling 5 sets of headphones?

"The biggest complaint I hear personally, is not that the earbuds are too expensive, but that the earphone jack has a lot of other uses--for instance allowing retailers to run credit cards in mid-air. Sure there's a dongle, but you can use that in mid air with only two hands!"

Another use: us pro-audio guys use apps on our iPhones for PA system checkout and analysis, as well as for walk-in/walk-out and break music. (Well, I use my old iPod Classic for break music, because I need the phone for when the tour manager calls/texts me.)

I suppose this will be moot once mixing console manufacturers start putting Bluetooth receivers in their products.

"This will only result in them losing more market share to the Android devices, so they're shooting themselves in the foot."

Except that the Android market is completely follow-the-leader and Samsung will remove the 1/8" jack from the next Galaxy model, and then the lower-tier makers will do likewise.
