For me it’s the notification light you used to find on older phones, was particularly good to know if your phone was charged without picking it up
I used to have a similar problem - even if well reviewed, budget and midrange bluetooth earbuds would not last while budget-midrange wired earphones would last forever.
Think it’s just build quality for bluetooth buds. I got a set of Galaxy buds, 1st gen, roughly 3+ years and still running strong to this day. Was not cheap though.
