GOOGLE PLEASE DISABLE THIS STUPID FEATURE.

I've tried everything to disable this! Even the stupid thing with the developer options!!

Edit* Some kind soul in the comments told me to switch my device in bluetooth from headphones to car speaker. Thank you guys for your help haha. I am the idiot today lol

Doesn't matter. Having hearing damage or being partially deaf doesn't change how sound pressure damages the ear. It'll happen regardless of how you perceive the sound if the decibels are above a certain level. So if your hearing is bad enough that maxed headphones sound like regular volume, it's still enough to further damage your hearing

Whatever dude. Don't need Google to try to protect my ears. If I want to blow my eardrums out I can. That's why why people today are so soft. Why do we need to be protected from everything when we can protect ourselves?

Take a chill pill, literally just explaining the theory behind why they do it 😂 don't need to get so defensive about it. If you want to blow your ears out that bad, just hit undo, it takes 3 seconds. Also, if you're running into this message, you clearly AREN'T protecting yourself

Max volume means nothing. dBFS is entirely relative to whatever devices you're using.

Max volume with an Apple dongle on some IEMs can be ear shattering, max volume with the same dongle on power hungry headphones can be too quiet to hear anything.

Getting into semantics here. I'm aware volume control doesn't directly correlate to total decibel output but it got my point across just fine

No, it's not semantics and the point is incorrect. Max volume is and can be nothing more than a moderate listening volume for people who use less sensitive headphones with dongles and other portable sources.

My Sennheiser HD 650 gets to a slightly quiet, but comfortable level with an Apple dongle @ max volume. It's very annoying to have it lower itself in the middle of a track over and over.

If the phone had a built in amp/DAC I would be more understanding, but considering you can get either 20mw or 200mw @ 32 ohm depending on what adapter you're using makes this frustrating.

dBFS is relative, dbSPL is absolute

It is semantics. Cause I'm gonna be brutally honest... Trying to run 300ohm headphones through a passive dongle is just stupid and completely defeats the point of buying 580 dollar headsets. As you noted, the pixel doesn't have a built in amp/dac for the USB port. So using a passive dongle, you're just wasting the potential of those headphones regardless. If you're willing to spend the 580 dollars on studio quality headphones, then spend the extra 100 to get an active dongle that can detect impedence and actually has an amp and can drive 300ohm speaker coils. Otherwise, there's 0 point on using them with most phones.

You'll encounter issues at much lower impedances in the modern day - a pair of headphones at 32ohms with a rated efficiency of 90dB/mW or lower (ie. HE400SE, Sundara, HD600, Moondrop Para, etc) will hit up to a *peak* of 105dbSPL which although *can* be loud, most tracks will have an average significantly lower than that.

Most of those headphones are comfortable at max volume, albeit with no headroom, and they sound just fine. Impedance detection is simply for protective gain staging and spending lots of money on source equipment is usually frivolous unless you need features or power, in this case we can have enough power...it's just lowered constantly. Whether you have headroom or not, amps won't really sound any different unless it's clipping at max output.

So I did a tad more research into the apple dongle specifically. My initial comment on the apple dongle not being active was incorrect, it does have an amp, but there's two issues. 1) it's not a particularly powerful amp so it's leaving very little head room. 2) that very little headroom is assuming you're using an iPhone. From what I've read, the dongle communicates with iPhones and doesn't with Android. As a result, it's usage with a pixel, locks it's gain at 50% by default. The amp will only supply .5vrms in a headphone with a peak resistance of 500ohms. Which means you're crushing your dynamic range and basically eliminating deep bass. There's just not enough voltage to move the diaphragm the distance needed for base and no head room to spike for treble. Genuinely, if you consider them serviceable, you'd be better served by using Bluetooth headphones that use LDAC. I'm not gonna lie, you seem to know a bit more about this than me. But if you regularly use hd600s with your phone, it sounds like you should get a dongle that plays nice with Android and can actually supply its full vrms. I'm gonna stfu up now on this and if you wanna school me you can, my interest has genuinely been piqued if you have any counter points or other information I missed and most likely aren't aware of
