How do you know when you get a call?  Does the headset vibrate at all?  I have the LG Tone Pro 750 and like it.  This is more geared toward exercise.  I am looking for something like this.  

Asked by: gminator
Thanks for your question. Our UA JBL Flex lets you know that you've got a call by playing your ringtone on the earphones. It doesn't vibrate at all and is rated IPX5+ Sweatproof which makes it resistant to sweat and moisture. If you have more questions, please contact us so we can help you. https://bit.ly/2zwFkYM

I purchased my first pair a little over a month ago. Within the first 2 weeks they stopped charging, luckily I was able to exchange this pair in store. No big deal, things happen. Fast forward 3 more weeks and pair #2 stopped charging. Any thoughts?

I'm beyond frustrated. Nearly every time I pause what I am listening to I have trouble reconnecting. It connects fine in the morning when I first turn it on. Then most other times I have to turn it off, then turn it back on 2x to pair up and start again
