Review on CUIZI Wireless Earbuds Bluetooth Headphones, 5.0 HD Stereo Sound Wireless Headset, Waterproof IPX7, Built-in Mic, Noise Canceling, Long Playtime, Charging Case by Heather Johnson

First of all, these are AMAZING things. When you receive the headphones, you need to charge the charger and the headphones. As soon as the light on the headphones goes out, they are being charged. As soon as the indicator on the charger goes out, it is fully charged. NOW I don't know how long the charge will last after a full charge, but I only used it for 2 hours. I WILL SAY THESE THINGS ARE DEFINITELY WATERPROOF. I'm throwing one in the paint because I thought I had an old headset with a cord and I just let go when I took it out and it fell in the paint. I rushed to wash them with just water and they still worked AMAZING.
