JBL Reflect Mini Bluetooth in-Ear Sport Headphones, Black https://www.amazon.com/dp/B015XA2XDI/ref=cm_sw_r_cp_api_i_WL1mCbB036TW2

Now... I’ve had mine for a few years and the reviews were not so bad on Amazon when I got them.

I own two pairs. One I leave at work and one I leave around the house.

They’ve been awesome. Stay in position. Last for a week (using 1-2 hours a day depending on workout). Have solid noise protection. I doubt they’re rated, but they provide noise protection that is slightly worse than a disposable foam ear plug.

My biggest hassle is juggling the connection between my phone and my watch. You just have to hold the power button when you turn it on and then select it in whichever device you are using that day (if both devices are on and next to each other, it will connect to the previously used device).
