Battery should last for more than an hour. I have a cheap ($25) Anker earbuds. They do the job

BUT the fit is no match for what I get from Shure (wired) 2xx or 5xx. So whereas the battery lasts for hours on end, I have to push on the buds inside my ear canal every 200M (running) with the Ankers vs never with Shure's foam tips and over the ear cable.

So if $150 is within your budget, you may want to consider Shure bluetooth earbuds
