The WF-1000XM4 is fine long as you don't update the firmware to 2.0.0.
Got mine as a refurbished unit couple months ago, came with 2.0.0 by default and it ended up almost nuking the battery after two months lol. I ended up having to get the battery replaced, plus downgrading to 1.3.3 and it's been smooth sailing ever since thankfully.
My issue has been the right earbud getting capped at ~10% volume - left is fine, right is almost inaudible. Luckily didn't have the battery issues others had with 2.0.0
