Mobile phones with reportedly great headphone jack SQ

I think others will agree that, audiophile hogwash apart, reliable information on which current models really have great SQ (decent volumes, great sound stage, etc.) is pretty scarce, to say the least.

So much so that, all could learn about two specific models I still own (Xiaomi Mi A1 and Moto X) was from hearsay, mostly.

So I was wondering if we could hear from other models' onwners (backed up perhaps, by what's in their specsheets) how great their headphone jack sound quality actually is.

At the very least, I think such reports might help us HA members choose their next phone, who knows?

The closest I would be able to report was already reported on this forum, the Lightning to 3.5mm headphone adapter, which is basically a USB DAC/ADC with a proprietary connection, specifically for iPhones without a headphone jack.

Well, that adapter is one way to ensure consistent headphone experience across devices. I can't say the same about other vendors' adapters for, say, USB-C, since some phones/adapters are designed to pass through a signal directly from the port, instead of acting as a DAC/ADC on the USB interface.

The only other interface, which I actually use more often than the adapter, would be the AirPods, and those aren't easily measured, and quality is measurably lossy, due to the AAC compression, but unlikely to be audibly perceptible to most users.

Almost all Qualcomm devices will use the same integrated DAC/amp, so they'll be very similar aside from software differences like how high the volume goes.  Output is a solid 15-16 effective bits if I remember correctly.  Good enough that you'll be limited by something else.

That I didn't know. Thanks!

Would you say that "something else" also entails OS updates, as these guys here at this Xiaomi forum seemed to conclude?

No, I don't think those are likely to matter unless Qualcomm changes their audio driver.

It sounds to me like they're asking about some kind of DSP effect in the included software.  I don't usually use that sort of thing so I can't comment.

Check out the reviews at gsmarena.com, they provide measurements of the audio output of the cellphones they test, and they test a lot.

Great stuff. Though I'd stumbled upon them previously, it didn't take much heed of how their tests seem to be carried out in a objective and professionally done manner.

I'm also impressed (but not surprised) with the Xiaomi M1 A1's figures in particular - which perfectly match the SQ I've been getting from this phone, coupled with the Sennheiser HD580 headphones directly connected to it: powerful and detailed sound!

Thanks for directing me to that.

It's indeed hard to find a phone which introduces audible defects into audio output.
It either has enough max output power or hasn't.
Keep calm and opusenc --bitrate 128

My Galaxy S9 sounds damn good, I know that much.
