I'm looking for new Bluetooth earbud to use in my office and while riding. I'd like something waterproof - but I've never had an issue with 'non-waterproof' earbuds. For reference, here are examples I currently have and use:

Savor M1100 | Plantronics - I've had it for years and like it, but the battery life is getting very short.

Marque 2 M165 | Plantronics - this is my newer one but the mic is cutting out and it has weak connectivity.

Here are my requirements:
I do not want stereo earbuds
It must have the ear-loop option to secure it
I don't want anything completely covers the ear (no noise isolation).

Anybody have a recommendation that's better than the linked options?
