What's the output impedence?
Ken Rockwell has measured at 3.18. Slightly disappointing but still lower than Pono and AK240.
Just got a response from Ken Rockwell asking him to review the iPhone 6s (Plus):
"My 6s+ arrived Friday.
I’m working on it.
Best part is you can play directly from it to an AirPort Express, and feed that to the DAC or your choice, so the phone itself doesn’t matter
Thanks!

Isn't that number for the previous iPhone 6 plus rather than the iPhone 6S plus?
The iPad Air 2 has an output impedance below 1 ohm so I will be very disappointed if the 3 ohm is correct.
You guys are right. A friend had emailed me about it. Seems we both mistook it for the S model. Good to know he has one and measurements are coming soon. I'm pretty sure it's over 1 but hopefully it's under 3.

New review on iPhone 6s sound quality. Mainly better bass respond and better clarity....hell, the iPhone 6 was plenty of clarity and solution, bass was in the warmer side....and this one has even more clarity and bass respond ? Wow....iPhone 6S plus or LG V10 ?
Also another more in depth audio performance measurements and all the phone techs

He said it frequency respond is FLAT....even better than some dedicated Audiophile DAPs....
Low impedance load is perfectly fine!
Harmonic ...just like a tube amplifier ?
Sound quality better than some outboard DAC ?
Enjoy it
Holy crap that was insulting.
Called AppleCare-
Supervisor apparently said that because you can't hear it with the included Apple earphones, which are made for the iPhone, naturally, that the engineers couldn't do anything about this "issue" and that this is an "issue" that would need to be taken up with the earphone manufacturer...
Wait, really? So, the 'Made for iPhone' certification process is also meaningless? That's just a stupid response.
I ended up returning my 6S on Friday (not just because of the buzzing). I really doubt at this point that Apple is going to openly acknowledge an issue that's only a problem for a tiny minority of users. Maybe they will introduce some revision quietly in the future. But I can't imagine them telling any particular user: "you can swap this phone for this one that works fine", since they would have to offer that for every user. Similar to the TSMC / Samsung case.
Could this buzzing be caused by the chipset? It's a fact that the Samsung chipset drains more battery and heats more. Maybe iPhone 6s' with Samsung chipset make a buzzing sound whereas 6s' with TMSC chipset do not?
