At first I didn't feel comfortable pairing it with my other devices. I'm still a little annoyed about that. Secondly, charging was a fun chore - the instructions state that when plugged in, a red LED will appear and the LED will turn off when charging. When I plug mine in, the LED is FLASHING red and not charging. . I have to unplug and plug it back in for the LED to stay red. Then, when it's charging (I think), the LED doesn't go out, it changes to BLUE. Holding the power button for 6 seconds to pair actually turns off the headphones as the instructions say. There are 3 or 4 different types of beeps that you need to understand what they mean in order to use them. I was about to complain about the battery life but I don't know if I fully charged mine. We are currently assuming a good battery life. Once charged and paired the sound is good, the weight on my head is light and I use them with my iPhone, desktop, laptop and some things I got from Kindle. After pairing it works great. In comparison, I have a pair of running headphones that, when switched on, say "switch on, battery 6 hours" and "headphones connected".
