Zero wireless earbuds died in 3–4 months — what should I buy next?

I got Zero K wireless earbuds 3–4 months ago (3000 PKR). They were fine at first, but now one side stopped working. Support just told me to wait.

My cheap wired handsfree (300–400 PKR) also last the same amount of time and sound okay. I expected the wireless ones to last at least a year.

What would you recommend — another wireless option in this range, or just go back to wired?
