As replied under another comment :
I'll be honest... I bought a Poco F4 because the value for money it offered was amazing. Plus, I could unlock the bootloader and shift to a custom ROM whenever I wanted (literally as soon as I could lol. Hate MiUI).
This phone doesn't have a headphone jack, but I was willing to make the jump since my general use of headphones is not as much as earphones. My ears get sweaty or scratchy after more than an hour straight of earphones, and around the same for headphones.
As a result, my overall usage is limited. So, when I got my TWS (paid ₹2000 for an okay pair, no dual device pairing, okayish build quality for the case and an okayish connection. Sound was good tho.)
My situation meant I didn't really use them as much, although they go for almost 4hrs straight. And if I put them in the case, they go for weeks without needing a charge (case has a built-in battery of 1200mAh). So, whenever I think I need the case to charge I just set it up overnight. The only sad part is it doesn't have dual device pairing. I use my laptop and phone together and I'd kill for this feature, but my budget is thin atm.
I know it's not everybody's case, but this is my case. And while I miss the jack, I don't notice the lack of it. Audio quality is good enough for me. The wires were honestly the worst part of my wired experience anyway.
