Probably preaching to the choir here, but headphone jacks are really a must, and USB-c adapters have their limits
Just randomly sharing my experience here. My sister told me a few weeks ago she was going to change for a new phone (a Motorola, she likes AOSP-like experience). I noticed that her new phone wouldn't get a jack.
"Yeah, I know, I hope I can make it work with a USB-adapter". She has nice headphones that she likes to use, so USB-C earplugs were not an option.
Fast forward to today, she told me the adapter she got starts to malfunction:
she has to twitch the jack in the adapter for the thing to work
when she plugs the adapter in, Google Assistant takes over and randomly starts skipping songs.
She's now considering getting wireless earbuds, but she's not a fan of having to recharge them to be able to use them, and is also cautious about the e-waste potential.
Of course it is possible, but it is an inefficient use of internal phone space. It adds another physical failure point. Increases risk of water entry. And adds construction/repair cost.
All for some thing few care about already and that number gets smaller everyday.
Sorry to be harshly pragmatic about it (I have a few niche hobbies myself) but it's time to let it go.
Google pixel 6 Pro with Google Buds Pro. Not really cheaped out but no aptx on the earbuds. I assumed low latency codec would be there when I bought a pro version of an earbud from a company that removes their headphone jack, but noooooooo.
Google buds aren't cheap but... They aren't really a prime example or wireless earbuds. Basically just the equivalent of the air pods. Decent sound, but a solid middle ground in terms of features and quality.
Take a look at some other options that do support aptx or at least Bluetooth LE Audio. Aim for BT 5.3 support, but BT 5.2 may be acceptable if you are happy with BT LE Audio latency.
I use the Sony WF-1000XMS with BT LE Audio on the Steamdeck and the latency is fine for most gaming. Latexy seems to be around 30-100ms at my best estimation (depending on the quality and complexity of the audio being transmitted).
But the WF-1000XMS don't support aptx. There are lots of devices that do though. I'd recommend looking for aptx-ll specifically, but aptx-hd is also a massive improvement.
As a side note, the reason I use WF-1000XMS is for the excellent ANC (I'm autistic), so I am not recommending them as gaming earbuds, but just as an example of quality earbuds that work for me.
That's not true. It depends on the codecs both devices use. But regardless, I mostly listen to podcasts and my hearing is by far the limiting factor in audio quality.
There is no "mp3 quality", as that can vastly vary depending on bitrate. And what is HD quality music supposed to be? I bet you couldn't reliably differentiate high quality mp3, CD audio and completely uncompressed wav in a series of blind tests.
