Just FYI the XM4s are significantly lighter and smaller. I could never get the 3s to stay in my ear, they were just too heavy… the new ones are much better. You need to jiggle a bit to get the fit snug but once they are in, they stay and the fit is comfortable. Still not as easy a fit as AirPods but the sound benefits are worth it for me.
Could you jog with the XM4s and have them stay in?

my gut says probably not, or at the very least I wouldn’t want to wonder if they might fall out. I’ve never tried because when I’m running I don’t care about audio quality so I use the Airpods which are lighter, less noticeable. But I can say I’ve walked around with the XM4s for the last two weeks, i walk fast, and they’ve never fallen out.
 
I find that odd. I've had the WF-1000XM3's 3x in 2019/2020 as I kept switching back and forth with the Air Pods Pro (difference in music quality and ambient quality range vs convenience and size) and didn't have any issue other than realising I could not pair 2+ devices and allow easy switching - which I think is fixed in the XM4's (mark IV).

Considering Ericsson created the Bluetooth technology, Sony's partnership with Ericsson at that time made Sony the 1st manufacturer of a bluetooth headset and that was shipping under the SonyEricsson brand, so I'm suprised. Did you update the firmware of those? Recall Apple had firmware issues for months on the AirPods Pro for many people. Nobody gave up on those. But each to their own.

Yes, updated the firmware. There’s quite a lot iOS users having issues with these since iOS 14.

Ultimately, LDAC users are likely to spend a fair bit of time listening to the 330kbps version. Unfortunately, the available resolution and 18kHz cut-off frequency are objectively inferior to CD quality, Qualcomm’s aptX, and SBC.

Many documentation states Qualcomm’s AptX is JUNK by comparison and you’re playing with numbers fudging out of thin are about a 18khz cut-off frequency lol.
 
Check out the Bowers & Wilkins pi7 instead. Best sound quality yet in the wireless earbuds range.

Just got mine and I must be doing something wrong. because phone call volume is insanely low, at full vol I can't hear the person on the other end and they can't hear me.

I cannot tell the diff between noise cancelling on and off.

The certainly do have impressive bass but they do not have mind blowing audio. Mids and highs pay the price.

Pairing isn't well managed

I've never owned a pair, but that sounds like they're not properly fitted in your ears. Or are faulty, or have some config setting limiting volume?
