Review on Vislla Bluetooth Headphones Sports Wireless Earbuds TWS BT5.0 Stereo Deep Bass Waterproof Earphones Noise Canceling Headset with Battery Display Charging Case & Built-in Mic (Black) by Jennifer Washington

I know I'm writing this pretty early because I used them for the first time today. Let me tell you they did exactly what I wanted them to do. I trained with them (running and weightlifting) and they stayed on my ears the whole time. Something cool about them is that putting them in the case turns them off automatically and taking them out automatically turns them on, so you don't have to remember to turn them off and on every time you use them. They also automatically mate upon extraction, and let me tell you, this happens almost instantly. It took me a few seconds to take them both out of the case and then immediately look at my iPod, they were already paired and ready to use, it really was that fast. I highly recommend it. I don't know if there is a difference but I have blue ones. If anything bad happens I'll probably update the review, but so far they're amazing.
