In your Bluetooth pairing list (I don't know what its called or look like in an Android but assume the basics are the same pretty much) do you get up Only WH-1000XM3 or do you get also LE_WH-1000XM3? From my understanding the latter one is for hand free (speaking on the phone) and the first for MUSIC (playback), I got from waging full out war initially, with devices, drivers and the WH-1000XM3 before taming the beast in it. The first can take calls but does it badly but plays music best, the second (LE_) plays music horribly bad like through a phone but since I got both of them visible and simultaneously active at the same time, my calls seems better or at least no one is complaining like before saying I sounded like I was in a different room than the headphones. Another thing I noticed was that, obviously, was when batteries got lower the quality went out the same window that the microphones jumped out of. But other than that it seems that they also work better when they are for the location and sound environment optimized through the Sony app, which i assume you have installed and updated. That app does not necessarily have to be activated just because the headphones are connected, sometimes you need to actually Press the "Activate/Connect" button, and Then it optimizes the headphones silent mode and I assume also the microphones...
Now remember that I'm really an Idiot when it comes to the WH-1000XM3, everyone more or less is, or layman of laymen I guess would be more diplomatic referring to others.😁.. So no Idiotproof guarantee comes with my advices unfortunately... Its late so ill throw in a story, just for the Hell of it, so to speak would be quite fitting... It is told and whispered in the echoing halls of Sony R&D section that only a very select few had full knowledge and wisdom about All the ins and out of these headphones, but they All apparently disappeared mysteriously the same day as the launch...which is probably why the X4's have so..., lets say.., "Conservative advancement" from the X3's. Anyways....(urr..shivering😥..) Actually, since that day, or apparently rather, if the box the device come in, is held in the right light, at the right angle, on Black Fridays, before opening the box for the first time the text "Lasciate ogne speranza, voi ch'intrate", most frequently translated as "Abandon all hope, ye who enter here"... "and enjoy the Sound of it", could be added for good measure appears in flaming letters..😭. I know for certain that its also written in a very famous book from mideavel times.😨 Not sure its true though, about the team and the box an' so....😎 It does seem to have a mind of its own though....🤔...🙄
