I'm no expert, but from friends that use this sort of "true wireless" earbuds, the problem my friends and I have with these are size. Size is probably the worst thing about these kinds of headphones, just on the basis that they're usually small, and as such, are easier to lose. Have it too big, or have something hanging out, and it looks a bit stupid imo, like Apple Airpods. If you want something "wireless" I'd suggest dealing with those Bluetooth earbuds which have one wire that goes around your neck, they even have the added convenience of just hanging it on your neck with the earbuds out. If you have the funds, buy a Bose pair, and if you're on a budget, my personal recommendation is The Coulax Sport Bluetooth earphones, not a top brand name, but I'm satisfied with it's use, as well as the CVC 6.0 passive noise cancellation. I do realize that these are sport headphones I'm talking about, but I'd suggest you see them as more sport-usable. These headphones focus on comfort and light weight while staying in your ear, and if one earbud falls out, you don't panic, perfect for sport use along with how most are sweat resistant, but also great overall use. I use my Coulax just for wireless listening on my laptop or phone, say for a video or a call as well.
TL;DR: Don't look at "smallest" as good, as these types of headphones do have major convenience and QOL problems.
