I got this product because it was on sale. I didn't expect it to be as well built as it is. It says 20 hours of listening time so I expected maybe 10. It is pretty darn close to 20. I usually go a few days between charging. I use them for my 40 minute walk to and from work as well as throughout the day. They stay synced to my phone all day long and hold a charge quite well.

This is a great headset. I’ve had two others in the past and the battery power on this one is amazing. The only problem I have is it does not warn you when the battery is low, it says “Please recharge now” then it’s off. I would recommend it to a friend and funny enough one of my friends recommended it to me.

Besides hearing the wind outside if you're on the phone, these are sturdy and worth the money.
