Update 1/6/20: So far they have continued to perform great for running. They've easily survived a couple of rain runs and still haven't fallen out of my ear while running. Upgrading my 4 stars to 5 stars as they exceeded my $30 expectations. Original Review: I have to say that I like this form factor without the cable connecting the headphones. They connect and disconnect easily and quickly when placed back on the charger. I haven't seen a way to unplug them or turn them off when disconnected from the charger. I haven't tested how waterproof they are, but they seem to seal well enough to work in the rain. They are quite light and do not fall out of your ears when running. I'll have to test their battery life before I can say if they're worth the $30 price tag, but that doesn't seem unusual given the form factor and water resistance.
