I actually ordered a few of these for myself and as Christmas gifts back when they were on sale last time. Overall, I’m pretty happy with them. They were a little smaller than I expected, but that’s not a bad thing. They paired with my smartphone quickly and easily, and they have pretty decent sound as well. It has a rechargeable battery that can last up to 8 hours on a full charge. It also has a built in microphone to accept hands-free calls, but I have yet to try that feature out.
