What are the chances the coil whine goes away?
Got a tip for us?

I just got another unit and both have coil whine.

What are the chances the coil whine goes away?
Not usually the case that it fixes itself.
Is the noise at all a function of the power supply being connected or not connected?
If it only occurs with the power supply connected, try it with a ground plug rather than the prongs directly attached to the power supply.
I am using it right now using the battery and haven’t plugged it in. I didn’t try it in store as both units are low but still noticeable. Both units sounded the same.

No adapters or anything being used.
This noise is fairly tied to design, with variations attributed to tolerances of suspect components (coils, capacitors, etc.). When I heard the sound in question on an Apple device for the first time, it didn't feel like the first time I've ever heard the sound.
Swapping is a hassle, and there's no assurance that the replacement hardware doesn't sound the same. However, an exchange for this reason does signal something to the manufacturer to investigate and improve upon. It's really up to you, and your sensitivity to the issue.
Do you think I'll get used to it? It is very low and slightly annoying probably because I am thinking about it.
I don't think you'll get used to it in a way that makes you not hear it. But like a lot of hardware these days, the MBP isn't the only device making this type of sound. If it's any consolation, I had a 2018 Mac mini that made this sound, and it was used for audio tasks. I replaced it recently only for upping the SSD and not for an audio issue.
On both units it does it even when booting up. I don't have it setup with any external devices. I think I'm gonna keep it since it is really low.
Documented the issue with a service agent online and scheduled a Genius Bar reservation for this Thursday. Here's another recording of the noise. Again, rename .pdf to .m4a to listen. At 00:01, the power button is pressed and starts booting. Then at 00:26, I'm logging-in to the machine. The noises appear both with adapter connected and on battery power.

Just turned Wi-Fi off, then shutdown. After power on, I could still hear the noises during boot-up. It's also not connected to any external devices, and haven't yet imported any data from my 2013 MBP. It's running with a test account with all updates applied, and nothing else configured.

Disappointing to even see the words 'coil whine' in 2019 for a $2200+ machine in an aluminum enclosure. I had a PC laptop do that and back it went.
I have tinnitus as well and I could still hear it. Good luck OP.

Some have said they hear this mostly when heavy SSD access is underway.
This is really unfortunate. Could it be an Intel issue? I don't blame Apple entirely as there are similar issues with ThinkPads, Dells, etc. But the Late-2013 MBP I've had for 6+ years has no coil whine at all.
Something happened along the way. But what?[automerge]1574042863[/automerge]
Tried both battery power and adapter with no difference and no external devices connected. With regard to checking the machine before leaving, I opened the box at the Apple Store and performed a visual inspection with an employee present to make sure there were no imperfections and that it could boot to the desktop. But listening to coil whine at the store will be hard because of how noisy the store is, which is why I'm bringing along a recording they can listen to. I suppose they can always take the machine to their back rooms and listen there.

Very interesting. I downloaded Cinebench R20 and while dragging it from the disk image to the Applications folder, it made a steady whining noise during copy and stopped after completion. The same thing happened while making a duplicate copy of iMovie, a 2.8GB app. It could very well be storage-related.
I can't say where I hear anything even remotely resembling Coil Whine in the OP's audio clip (even using headphones), either. Though I can clearly hear it in this (non-Mac) video...

...and if I heard something like that coming out of my brandie-new MBP it'd be heading back to Apple for replacement.
I guess you hear this kind of noise, if you do, its just the ssd noise so nothing wrong with your mac
But depends of your level of your noise, if its more than this, then you can replace it. You should not hear this when you normal work, you should hear this in a very quiet room/when you put your ear next to the speaker where the ssd is placed

Hi milhous,
The noise I hear in your second audio file resembles that found in fokmik's YT link (above) and this MBP-specific video...

I called Apple. Follow these steps. Basically non existent now.
1. Safe Mode: Shut down —> Power —> Shift
2. Reset System Management Controller: Shut down —> Power —> Shift + control + option + power
3. Reset RAM: Shut down —> Power —> Control + option + P + R

...perhaps you can give this a try and report back here for those of us following this?!
